Detailed Description

A literal parser that processes input literals for arguments that change properties on a target object.

Constructor & Destructor Documentation

Joutsen.ArgumentsParsing.TargetPropertyParser< ValueType >.TargetPropertyParser	(	ArgumentReader< ValueType >	reader,
		String	name,
		bool	isRequired,
		ValueType	defaultValue,
		string	propertyName,
		bool	isFlag = `false`
	)

Creates a new instance of the parser.

Parameters

reader	the reader that extracts the argument literals from the input
name	the name of the argument that is processed by the parser
isRequired	true, if the argument is mandatory and needs to be present in the input, false otherwise
defaultValue	the value that is used to change the property in the target object if the argument is optional and was not found in the input
propertyName	the name of the property that the parser modifies
isFlag	determines if the parser is processing a flag or an argument which can have additional values

virtual ParseResult Joutsen.ArgumentsParsing.TargetPropertyParser< ValueType >.Parse	(	ArgumentsIterator	args,
		object	target,
		string	name = `null`
	)

virtual

Parses the relevant argument in the list and modifies the target object with it.

Parameters

args	the list of input strings that need to be parsed
target	the receiver of the parsed values
name	an optional name of the argument that is being parsed. This is usually only used for arguments that are identified by their name.

Returns: the modified target object and the arguments that still need to be parsed as a PareseResult instance.

void Joutsen.ArgumentsParsing.TargetPropertyParser< ValueType >.Reset ( )

Clears the parsers state if any in order to prepare it for a new run.

object Joutsen.ArgumentsParsing.TargetPropertyParser< ValueType >.SetDefaultValue	(	object	target,
		string	name = `null`
	)

Sets the default value of the argument to a target object.

Parameters

target	the receiver of the default value
name	an optional name of this argument. This is usually only used for arguments that are identified by their name.

Remarks: This method is used for optional arguments which were not parsed because of a value in the input list. Implementations should raise an exception if the argument is mandatory or return the unmodified target object if they do not offer a default value.
