Detailed Description

This pattern matches a list of values separated by commas (or another string), each of which have to match a pattern given to the constructor. With two additional parameters, the number of elements this list has to have can be specified. If none is specified, the list may have zero or more entries.

Constructor & Destructor Documentation

List()

Patterns::List::List	(	const PatternBase &	base_pattern,
		const unsigned int	min_elements = 0,
		const unsigned int	max_elements = max_int_value,
		const std::string &	separator = ","
	)

Constructor. Take the given parameter as the specification of valid elements of the list.

The three other arguments can be used to denote minimal and maximal allowable lengths of the list, and the string that is used as a separator between elements of the list.

Definition at line 435 of file parameter_handler.cc.

~List()

Patterns::List::~List ( )

virtual

Destructor.

Definition at line 453 of file parameter_handler.cc.

Member Function Documentation

match()

bool Patterns::List::match ( const std::string &  test_string ) const

virtual

Return true if the string is a comma-separated list of strings each of which match the pattern given to the constructor.

Implements Patterns::PatternBase.

Definition at line 461 of file parameter_handler.cc.

description()

std::string Patterns::List::description ( ) const

virtual

Return a description of the pattern that valid strings are expected to match.

Implements Patterns::PatternBase.

Definition at line 506 of file parameter_handler.cc.

clone()

PatternBase * Patterns::List::clone ( ) const

virtual

Return a copy of the present object, which is newly allocated on the heap. Ownership of that object is transferred to the caller of this function.

Implements Patterns::PatternBase.

Definition at line 524 of file parameter_handler.cc.

create()

List * Patterns::List::create ( const std::string &  description )

static

Creates new object if the start of description matches description_init. Ownership of that object is transferred to the caller of this function.

Definition at line 540 of file parameter_handler.cc.

memory_consumption()

std::size_t Patterns::List::memory_consumption ( ) const

virtual

Determine an estimate for the memory consumption (in bytes) of this object.

Reimplemented from Patterns::PatternBase.

Definition at line 531 of file parameter_handler.cc.

Member Data Documentation

max_int_value

const unsigned int Patterns::List::max_int_value = std::numeric_limits<unsigned int>::max()

static

Maximal integer value. If the numeric_limits class is available use this information to obtain the extremal values, otherwise set it so that this class understands that all values are allowed.

Definition at line 376 of file parameter_handler.h.

pattern

PatternBase* Patterns::List::pattern

private

Copy of the pattern that each element of the list has to satisfy.

Definition at line 445 of file parameter_handler.h.

min_elements

const unsigned int Patterns::List::min_elements

private

Minimum number of elements the list must have.

Definition at line 450 of file parameter_handler.h.

max_elements

const unsigned int Patterns::List::max_elements

private

Maximum number of elements the list must have.

Definition at line 455 of file parameter_handler.h.

separator

const std::string Patterns::List::separator

private

Separator between elements of the list.

Definition at line 460 of file parameter_handler.h.

description_init

const char * Patterns::List::description_init = "[List"

staticprivate

Initial part of description
