-\label{sec:org5c8f3ee}
+\label{sec:orged5584a}
 7Units splits its code into three main packages:

-Units are internally represented by the abstract class \texttt{Unit}.

The dimension is calculated from the base unit when needed; the variable is just a cache.  It has two constructors: a package-private one used to make \texttt{BaseUnit} instances, and a protected one used to make general units (for other subclasses of \texttt{Unit}).  All unit classes are immutable.

 Units also have two conversion functions - one which converts from a value expressed in this unit to its base unit, and another which converts from a value expressed in the base unit to this unit.  In \texttt{Unit}, they are defined as two abstract methods.  This allows you to convert from any unit to any other (as long as they have the same base, i.e. you aren't converting metres to pounds).  To convert from A to B, first convert from A to its base, then convert from the base to B.

 \item[{USCustomary}] A static utility class with instances of common units in the US Customary system (not to be confused with the British Imperial system; it has the same unit names but the values of a few units are different).
 \end{description}
 \subsection{Prefixes}
-\label{sec:org1bd7050}
+\label{sec:org40fa3a0}
 A \texttt{UnitPrefix} is a simple object that can multiply a \texttt{LinearUnit} by a value.  It can calculate a new name for the unit by combining its name and the unit's name (symbols are done similarly).  It can do multiplication, division and exponentation with a number, as well as multiplication and division with another prefix; all of these work by changing the prefix's multiplier.
 \subsection{The Unit Database}
-\label{sec:orgc8dc0e4}
+\label{sec:org0a33326}
 The \texttt{UnitDatabase} class stores all of the unit, prefix and dimension data used by this program.  It is not a representation of an actual database, just a class that stores lots of data.
 
 Units are stored using a custom \texttt{Map} implementation (\texttt{PrefixedUnitMap}) which maps unit names to units.  It is backed by two maps: one for units (without prefixes) and one for prefixes.  It is programmed to include prefixes (so if units includes "metre" and prefixes includes "kilo", this map will include "kilometre", mapping it to a unit representing a kilometre).  It is immutable, but you can modify the underlying maps, which is reflected in the \texttt{PrefixedUnitMap}.  Other than that, it is a normal map implementation.
 
 Prefixes and dimensions are stored in normal maps.
 \subsubsection{Parsing Expressions}
-\label{sec:orgb7ee1da}
-Each \texttt{UnitDatabase} instance has four \hyperref[sec:orgd351c2f]{ExpressionParser} instances associated with it, for four types of expressions: unit, unit value, prefix and dimension.  They are mostly similar, with operators corresponding to each operation of the corresponding class (\texttt{LinearUnit}, \texttt{LinearUnitValue}, \texttt{UnitPrefix}, \texttt{ObjectProduct<BaseDimension>}).  Unit and unit value expressions use linear units; nonlinear units can be used with a special syntax (like "degC(20)") and are immediately converted to a linear unit representing their base (Kelvin in this case) before operating.

 There are two types of data files: unit and dimension.
 
 Unit files contain data about units and prefixes.  Each line contains the name of a unit or prefix (prefixes end in a dash, units don't) followed by an expression which defines it, separated by one or more space characters (this behaviour is defined by the static regular expression \texttt{NAME\_EXPRESSION}).  Unit files are parsed line by line, each line being run through the \texttt{addUnitOrPrefixFromLine} method, which splits a line into name and expression, determines whether it's a unit or a prefix, and parses the expression.  Because all units are defined by others, base units need to be defined with a special expression "!"; \textbf{these units should be added to the database before parsing the file}.

 The \texttt{View} is the part of the frontend code that directly interacts with the user.  It handles input and output, but does not do any processing.  Processing is handled by the presenter and the backend code.
 
 The \texttt{View} is an interface, not a single class, so that I can easily create multiple views without having to rewrite any processing code.  This allows me to easily prototype changes to the GUI without messing with existing code.

 The \texttt{Presenter} is an intermediary between the \texttt{View} and the backend code.  It accepts the user's input and passes it to the backend, then accepts the backend's output and passes it to the frontend for user viewing.  Its main functions do not have arguments or return values; instead it takes input from and provides output to the \texttt{View} via its public methods.
 \subsubsection{Rules}

+\label{sec:org29011d5}
 The \texttt{Presenter} has a set of function-object rules that determine some of its behaviours.  Each corresponds to a setting in the \texttt{View}, but they can be set to other values via the \texttt{Presenter}'s setters (although nonstandard rules cannot be saved and loaded):

-\label{sec:orgc3e831c}
+\label{sec:org9c5f1fc}
 An \texttt{ObjectProduct} represents a "product" of elements of some type.  The units system uses them to represent coherent units as a product of base units, and dimensions as a product of base dimensions.
 
 Internally, it is represented using a map mapping objects to their exponents in the product.  For example, the unit "kg m\textsuperscript{2} / s\textsuperscript{2}" (i.e. a Joule) would be represented with a map like \texttt{[kg: 1, m: 2, s: -2]}.
 \subsection{ExpressionParser}
-\label{sec:orgd351c2f}
+\label{sec:org7f49fac}
 The \texttt{ExpressionParser} class is used to parse the unit, prefix and dimension expressions that are used throughout 7Units.  An expression is something like "(2 m + 30 J / N) * 8 s)".  Each instance represents a type of expression, containing a way to obtain values (such as numbers or units) from the text and operations that can be done on these values (such as addition, subtraction or multiplication).  Each operation also has a priority, which controls the order of operations (i.e. multiplication gets a higher priority than addition).
 
 \texttt{ExpressionParser} has a parameterized type \texttt{T}, which represents the type of the value used in the expression.  The expression parser currently only supports one type of value per expression; in the expressions used by 7Units numbers are treated as a kind of unit or prefix.  Operators are represented by internal types; the system distinguishes between unary operators (those that take a single value, like negation) and binary operators (those that take 2 values, like +, -, * or /).

 After evaluating the last token, there should be one value left in the stack - the answer.  If there isn't, the original expression was malformed.
 \end{enumerate}
 \subsection{Math Classes}
-\label{sec:orgdadbc0d}
+\label{sec:org48c9af9}
 There are two simple math classes in 7Units:
 \begin{description}
 \item[{\texttt{UncertainDouble}}] Like a \texttt{double}, but with an uncertainty (e.g. \(2.0 \pm 0.4\)).  The operations are like those of the regular Double, only they also calculate the uncertainty of the final value.  They also have "exact" versions to help interoperation between \texttt{double} and \texttt{UncertainDouble}.  It is used by the converter's Scientific Precision setting.
 \item[{\texttt{DecimalComparison}}] A static utility class that contains a few alternate equals() methods for \texttt{double} and \texttt{UncertainDouble}.  These methods allow a slight (configurable) difference between values to still be considered equal, to fight roundoff error.
 \end{description}
 \subsection{Collection Classes}
-\label{sec:org7421746}
+\label{sec:org9065607}
 The \texttt{ConditionalExistenceCollections} class contains wrapper implementations of \texttt{Collection}, \texttt{Iterator}, \texttt{Map} and \texttt{Set}.  These implementations ignore elements that do not pass a certain condition - if an element fails the condition, \texttt{contains} will return false, the iterator will skip past it, it won't be counted in \texttt{size}, etc. even if it exists in the original collection.  Effectively, any element of the original collection that fails the test does not exist.

Units listed in the exceptions file (\texttt{src/main/resources/metric\_exceptions.txt}) will be shown on both sides.  This is a way to reduce the number of options you must search through if you only convert one way.  The expressions tab is unaffected.
 \item[{Show Duplicates in "Convert Units"}] If unchecked, any unit that has multiple names will only have one included in the Convert Units lists.  The selected name will be the longest; if there are multiple longest names one is selected arbitrarily.  You will still be able to use these alternate names in the expressions tab.

 Brackets can be used to manipulate the order of operations, and nonlinear units like Celsius and Fahrenheit cannot be used in expressions.  You can use a value in a nonlinear unit by putting brackets after it - for example, degC(12) represents the value 12 \textdegree{} C
 \subsection{Other Expressions}

 There are also a simplified version of expressions for prefixes and dimensions.  Only multiplication, division and exponentation are supported.  Currently, exponentation is not supported for dimensions, but that may be fixed in the future.

 7Units is a program that can convert between units.  This document details the internal design of 7Units, intended to be used by current and future developers.

 \subsection{Packages of 7Units}
-\label{sec:orged5584a}
+\label{sec:org8a6985b}
 7Units splits its code into three main packages:
 \begin{description}
-\item[{\texttt{sevenUnits.unit}}] The \hyperref[sec:orgf969629]{unit system}
+\item[{\texttt{sevenUnits.unit}}] The \hyperref[sec:org76c2c26]{unit system}
 \item[{\texttt{sevenUnits.utils}}] Extra classes that aid the unit system.

+\item[{\texttt{sevenUnitsGUI}}] The \hyperref[sec:orgbb1d346]{front end} code
 \end{description}
 \texttt{sevenUnits.unit} depends on \texttt{sevenUnits.utils}, while \texttt{sevenUnitsGUI} depends on both \texttt{sevenUnits} packages.  There is only one class that isn't in any of these packages, \texttt{sevenUnits.VersionInfo}.

-Dimensions represent what a unit is measuring, such as length, time, or energy.  Dimensions are represented as an \hyperref[sec:org9c5f1fc]{ObjectProduct}<BaseDimension>, where \texttt{BaseDimension} is a very simple class (its only properties are a name and a symbol) which represents the dimension of a base unit; these base dimensions can be multiplied to create all other Dimensions.

 Units also have two conversion functions - one which converts from a value expressed in this unit to its base unit, and another which converts from a value expressed in the base unit to this unit.  In \texttt{Unit}, they are defined as two abstract methods.  This allows you to convert from any unit to any other (as long as they have the same base, i.e. you aren't converting metres to pounds).  To convert from A to B, first convert from A to its base, then convert from the base to B.

 \subsection{Prefixes}
-\label{sec:org40fa3a0}
+\label{sec:org1504786}
 A \texttt{UnitPrefix} is a simple object that can multiply a \texttt{LinearUnit} by a value.  It can calculate a new name for the unit by combining its name and the unit's name (symbols are done similarly).  It can do multiplication, division and exponentation with a number, as well as multiplication and division with another prefix; all of these work by changing the prefix's multiplier.
 \subsection{The Unit Database}
-\label{sec:org0a33326}
+\label{sec:org1a286b2}
 The \texttt{UnitDatabase} class stores all of the unit, prefix and dimension data used by this program.  It is not a representation of an actual database, just a class that stores lots of data.
 
 Units are stored using a custom \texttt{Map} implementation (\texttt{PrefixedUnitMap}) which maps unit names to units.  It is backed by two maps: one for units (without prefixes) and one for prefixes.  It is programmed to include prefixes (so if units includes "metre" and prefixes includes "kilo", this map will include "kilometre", mapping it to a unit representing a kilometre).  It is immutable, but you can modify the underlying maps, which is reflected in the \texttt{PrefixedUnitMap}.  Other than that, it is a normal map implementation.
 
 Prefixes and dimensions are stored in normal maps.
 \subsubsection{Parsing Expressions}

Unit and unit value expressions use linear units; nonlinear units can be used with a special syntax (like "degC(20)") and are immediately converted to a linear unit representing their base (Kelvin in this case) before operating.

Each line contains the name of a unit or prefix (prefixes end in a dash, units don't) followed by an expression which defines it, separated by one or more space characters (this behaviour is defined by the static regular expression \texttt{NAME\_EXPRESSION}).  Unit files are parsed line by line, each line being run through the \texttt{addUnitOrPrefixFromLine} method, which splits a line into name and expression, determines whether it's a unit or a prefix, and parses the expression.  Because all units are defined by others, base units need to be defined with a special expression "!"; \textbf{these units should be added to the database before parsing the file}.

 \section{Front-End Design}
-\label{sec:org431a987}
+\label{sec:orgbb1d346}
 The front-end of 7Units is based on an MVP model.  There are two major frontend classes, the \textbf{View} and the \textbf{Presenter}.
 \subsection{The View}
-\label{sec:org5460ab6}
+\label{sec:orgae93ac0}
 The \texttt{View} is the part of the frontend code that directly interacts with the user.  It handles input and output, but does not do any processing.  Processing is handled by the presenter and the backend code.
 
 The \texttt{View} is an interface, not a single class, so that I can easily create multiple views without having to rewrite any processing code.  This allows me to easily prototype changes to the GUI without messing with existing code.

 \subsection{The Presenter}
-\label{sec:org4f735c1}
+\label{sec:org76432e4}
 The \texttt{Presenter} is an intermediary between the \texttt{View} and the backend code.  It accepts the user's input and passes it to the backend, then accepts the backend's output and passes it to the frontend for user viewing.  Its main functions do not have arguments or return values; instead it takes input from and provides output to the \texttt{View} via its public methods.
 \subsubsection{Rules}
-\label{sec:org29011d5}
+\label{sec:org5218ce5}
 The \texttt{Presenter} has a set of function-object rules that determine some of its behaviours.  Each corresponds to a setting in the \texttt{View}, but they can be set to other values via the \texttt{Presenter}'s setters (although nonstandard rules cannot be saved and loaded):

 \section{Utility Classes}
-\label{sec:org9889589}
+\label{sec:org59e5f0c}
 7Units has a few general "utility" classes.  They aren't directly related to units, but are used in the units system.
 \subsection{ObjectProduct}
-\label{sec:org9c5f1fc}
+\label{sec:org07580ff}
 An \texttt{ObjectProduct} represents a "product" of elements of some type.  The units system uses them to represent coherent units as a product of base units, and dimensions as a product of base dimensions.
 
 Internally, it is represented using a map mapping objects to their exponents in the product.  For example, the unit "kg m\textsuperscript{2} / s\textsuperscript{2}" (i.e. a Joule) would be represented with a map like \texttt{[kg: 1, m: 2, s: -2]}.
 \subsection{ExpressionParser}
-\label{sec:org7f49fac}
+\label{sec:orgb075c07}
 The \texttt{ExpressionParser} class is used to parse the unit, prefix and dimension expressions that are used throughout 7Units.  An expression is something like "(2 m + 30 J / N) * 8 s)".  Each instance represents a type of expression, containing a way to obtain values (such as numbers or units) from the text and operations that can be done on these values (such as addition, subtraction or multiplication).  Each operation also has a priority, which controls the order of operations (i.e. multiplication gets a higher priority than addition).
 
 \texttt{ExpressionParser} has a parameterized type \texttt{T}, which represents the type of the value used in the expression.  The expression parser currently only supports one type of value per expression; in the expressions used by 7Units numbers are treated as a kind of unit or prefix.  Operators are represented by internal types; the system distinguishes between unary operators (those that take a single value, like negation) and binary operators (those that take 2 values, like +, -, * or /).

 After evaluating the last token, there should be one value left in the stack - the answer.  If there isn't, the original expression was malformed.

 \subsection{Math Classes}
-\label{sec:org48c9af9}
+\label{sec:org1e73788}
 There are two simple math classes in 7Units:
 \begin{description}
 \item[{\texttt{UncertainDouble}}] Like a \texttt{double}, but with an uncertainty (e.g. \(2.0 \pm 0.4\)).  The operations are like those of the regular Double, only they also calculate the uncertainty of the final value.  They also have "exact" versions to help interoperation between \texttt{double} and \texttt{UncertainDouble}.  It is used by the converter's Scientific Precision setting.
 \item[{\texttt{DecimalComparison}}] A static utility class that contains a few alternate equals() methods for \texttt{double} and \texttt{UncertainDouble}.  These methods allow a slight (configurable) difference between values to still be considered equal, to fight roundoff error.
 \end{description}
 \subsection{Collection Classes}
-\label{sec:org9065607}
+\label{sec:org02e007a}
 The \texttt{ConditionalExistenceCollections} class contains wrapper implementations of \texttt{Collection}, \texttt{Iterator}, \texttt{Map} and \texttt{Set}.  These implementations ignore elements that do not pass a certain condition - if an element fails the condition, \texttt{contains} will return false, the iterator will skip past it, it won't be counted in \texttt{size}, etc. even if it exists in the original collection.  Effectively, any element of the original collection that fails the test does not exist.
