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.

Member Enumeration Documentation

OutputStyle

enum Patterns::PatternBase::OutputStyle

inherited

List of possible description output formats.

Capitalization chosen for similarity to ParameterHandler::OutputStyle.

Enumerator
Machine	Simple text suitable for machine parsing in the static public member functions for all of the built in inheriting classes. Preferably human readable, but machine parsing is more critical.
Text	Easily human readable plain text format suitable for plain text documentation.
LaTeX	Easily human readable LaTeX format suitable for printing in manuals.

Constructor & Destructor Documentation

List() [1/2]

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.

List() [2/2]

Patterns::List::List

(

const List &

other

)

Copy constructor.

Member Function Documentation

get_separator()

const std::string & Patterns::List::get_separator

(

)

const

Return the internally stored separator.

Definition at line 677 of file patterns.cc.

get_base_pattern()

const PatternBase & Patterns::List::get_base_pattern

(

)

const

Return the internally stored base pattern.

Definition at line 685 of file patterns.cc.

match()

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

overridevirtual

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 693 of file patterns.cc.

description()

std::string Patterns::List::description ( const OutputStyle style = Machine ) const

overridevirtual

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

Implements Patterns::PatternBase.

Definition at line 713 of file patterns.cc.

clone()

std::unique_ptr< PatternBase > Patterns::List::clone ( ) const

overridevirtual

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 757 of file patterns.cc.

create()

std::unique_ptr< List > Patterns::List::create ( const std::string & description )

static

Create a 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 774 of file patterns.cc.

memory_consumption()

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

overridevirtual

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

Reimplemented from Patterns::PatternBase.

Definition at line 765 of file patterns.cc.

Member Data Documentation

max_int_value

const unsigned int Patterns::List::max_int_value

static

Initial value:

=
    std::numeric_limits<unsigned int>::max()

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 456 of file patterns.h.

pattern

std::unique_ptr<PatternBase> Patterns::List::pattern

private

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

Definition at line 544 of file patterns.h.

min_elements

const unsigned int Patterns::List::min_elements

private

Minimum number of elements the list must have.

Definition at line 549 of file patterns.h.

max_elements

const unsigned int Patterns::List::max_elements

private

Maximum number of elements the list must have.

Definition at line 554 of file patterns.h.

separator

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

private

Separator between elements of the list.

Definition at line 559 of file patterns.h.

description_init

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

staticprivate

Initial part of description
