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() [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 680 of file patterns.cc.

get_base_pattern()

const PatternBase & Patterns::List::get_base_pattern

(

)

const

Return the internally stored base pattern.

Definition at line 688 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 696 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 716 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 760 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 777 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 768 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.
