Detailed Description

This pattern matches a list of comma-separated values each of which denotes a pair of key and value. Both key and value have to match a pattern given to the constructor. For each entry of the map, parameters have to be entered in the form key: value. In other words, a map is described in the form key1: value1, key2: value2, key3: value3, .... Two constructor arguments allow to choose a delimiter between pairs other than the comma, and a delimiter between key and value other than colon.

With two additional parameters, the number of elements this list has to have can be specified. If none is specified, the map may have zero or more entries.

Constructor & Destructor Documentation

Map() [1/2]

Patterns::Map::Map	(	const PatternBase &	key_pattern,
		const PatternBase &	value_pattern,
		const unsigned int	min_elements = 0,
		const unsigned int	max_elements = max_int_value,
		const std::string &	separator = ",",
		const std::string &	key_value_separator = ":"
	)

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

The four other arguments can be used to denote minimal and maximal allowable lengths of the list as well as the separators used to delimit pairs of the map and the symbol used to separate keys and values.

Member Function Documentation

match()

bool Patterns::Map::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 861 of file patterns.cc.

description()

std::string Patterns::Map::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 891 of file patterns.cc.

clone()

std::unique_ptr< PatternBase > Patterns::Map::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 941 of file patterns.cc.

create()

std::unique_ptr< Map > Patterns::Map::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 965 of file patterns.cc.

memory_consumption()

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

overridevirtual

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

Reimplemented from Patterns::PatternBase.

Definition at line 953 of file patterns.cc.

get_key_pattern()

const PatternBase & Patterns::Map::get_key_pattern

(

)

const

Return a reference to the key pattern.

Definition at line 1020 of file patterns.cc.

get_value_pattern()

const PatternBase & Patterns::Map::get_value_pattern

(

)

const

Return a reference to the value pattern.

Definition at line 1028 of file patterns.cc.

get_separator()

const std::string & Patterns::Map::get_separator

(

)

const

Return the separator of the map entries.

Definition at line 1036 of file patterns.cc.

get_key_value_separator()

const std::string & Patterns::Map::get_key_value_separator

(

)

const

Return the key-value separator.

Definition at line 1043 of file patterns.cc.

Member Data Documentation

max_int_value

const unsigned int Patterns::Map::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 591 of file patterns.h.

key_pattern

std::unique_ptr<PatternBase> Patterns::Map::key_pattern

private

Copy of the patterns that each key and each value of the map has to satisfy.

Definition at line 693 of file patterns.h.

min_elements

const unsigned int Patterns::Map::min_elements

private

Minimum number of elements the list must have.

Definition at line 699 of file patterns.h.

max_elements

const unsigned int Patterns::Map::max_elements

private

Maximum number of elements the list must have.

Definition at line 704 of file patterns.h.

separator

const std::string Patterns::Map::separator

private

Separator between elements of the list.

Definition at line 709 of file patterns.h.

key_value_separator

const std::string Patterns::Map::key_value_separator

private

Separator between keys and values.

Definition at line 715 of file patterns.h.

description_init

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

staticprivate

Initial part of description
