Detailed Description

The ArgumentOccurrence struct holds argument values for an occurrence of an argument.

Definition at line 194 of file argumentparser.h.

Constructor & Destructor Documentation

◆ ArgumentOccurrence() [1/2]

CppUtilities::ArgumentOccurrence::ArgumentOccurrence ( std::size_t index )

inline

Constructs an argument occurrence for the specified index.

Definition at line 241 of file argumentparser.h.

◆ ArgumentOccurrence() [2/2]

CppUtilities::ArgumentOccurrence::ArgumentOccurrence	(	std::size_t	index,
		const std::vector< Argument * >	parentPath,
		Argument *	parent )

inline

Constructs an argument occurrence.

Parameters

index	Specifies the index.
parentPath	Specifies the path of parent.
parent	Specifies the parent which might be nullptr for top-level occurrences.

The path of the new occurrence is built from the specified parentPath and parent.

Definition at line 254 of file argumentparser.h.

Member Function Documentation

◆ convertValues()

template<typename... RemainingTargetTypes>

std::tuple< RemainingTargetTypes... > CppUtilities::ArgumentOccurrence::convertValues ( ) const

Converts the present values to the specified target types.

There must be as many values present as types are specified.

Exceptions

Throws ArgumentUtilities::Failure when the number of present values is not sufficient or a conversion error occurs.

Remarks: Still experimental. Might be removed/adjusted in next minor release.

Member Data Documentation

◆ index

std::size_t CppUtilities::ArgumentOccurrence::index

The index of the occurrence.

This is not necessarily the index in the argv array.

Definition at line 201 of file argumentparser.h.

◆ path

std::vector<Argument *> CppUtilities::ArgumentOccurrence::path

The "path" of the occurrence (the parent elements which have been specified before).

Remarks: Empty for top-level occurrences.

Definition at line 212 of file argumentparser.h.

◆ values

std::vector<const char *> CppUtilities::ArgumentOccurrence::values

The parameter values which have been specified after the occurrence of the argument.

Definition at line 206 of file argumentparser.h.
