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 delimeter 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

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.

Definition at line 797 of file patterns.cc.

Patterns::Map::Map ( const Map other)

Copy constructor.

Member Function Documentation

bool Patterns::Map::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 837 of file patterns.cc.

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

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

Implements Patterns::PatternBase.

Definition at line 866 of file patterns.cc.

std::unique_ptr< PatternBase > Patterns::Map::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 918 of file patterns.cc.

std::unique_ptr< Map > Patterns::Map::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 938 of file patterns.cc.

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

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

Reimplemented from Patterns::PatternBase.

Definition at line 927 of file patterns.cc.

const PatternBase & Patterns::Map::get_key_pattern ( ) const

Return a reference to the key pattern.

Definition at line 985 of file patterns.cc.

const PatternBase & Patterns::Map::get_value_pattern ( ) const

Return a reference to the value pattern.

Definition at line 992 of file patterns.cc.

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

Return the separator of the map entries.

Definition at line 999 of file patterns.cc.

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

Return the key-value separator.

Definition at line 1005 of file patterns.cc.

Member Data Documentation

const unsigned int Patterns::Map::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 555 of file patterns.h.

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 647 of file patterns.h.

const unsigned int Patterns::Map::min_elements
private

Minimum number of elements the list must have.

Definition at line 653 of file patterns.h.

const unsigned int Patterns::Map::max_elements
private

Maximum number of elements the list must have.

Definition at line 658 of file patterns.h.

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

Separator between elements of the list.

Definition at line 663 of file patterns.h.

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

Separator between keys and values.

Definition at line 669 of file patterns.h.

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

Initial part of description
