CharLookup< T > Class Template Reference

#include <genesis/utils/tools/char_lookup.hpp>

Detailed Description

template<typename T>
class genesis::utils::CharLookup< T >

Simple lookup table providing a value lookup for each ASCII char (0-127).

The class provides a fast mapping from each char to the provided template parameter type.

Constructor & Destructor Documentation

CharLookup() [1/5]

CharLookup ( )

inline

Constructor that sets all values to the default value of the template parameter type.

Definition at line 74 of file char_lookup.hpp.

CharLookup() [2/5]

CharLookup ( T const &  init_all )

inlineexplicit

Constructor that sets all values to a given one.

Definition at line 81 of file char_lookup.hpp.

CharLookup() [3/5]

CharLookup ( std::initializer_list< T >  init )

inlineexplicit

Constructor that takes an initializer list of the template type.

The given list needs to have as many entries as the lookup table itself (see ArraySize), otherwise it throws.

Member Function Documentation

all_equal_to()

bool all_equal_to ( T  comp_value ) const

inline

Return whether all chars compare equal to a given value.

Definition at line 242 of file char_lookup.hpp.

get()

T get ( char  c ) const

inline

Return the lookup status for a given char.

Definition at line 218 of file char_lookup.hpp.

get_chars_equal_to()

std::string get_chars_equal_to ( T  comp_value ) const

inline

Return a std::string containg all chars which have lookup status equal to a given value.

Definition at line 228 of file char_lookup.hpp.

operator=() [1/2]

CharLookup& operator= ( CharLookup< T > &&  )

default

operator=() [2/2]

CharLookup& operator= ( CharLookup< T > const &  )

default

operator[]()

T operator[] ( char  c ) const

inline

Return the lookup status for a given char.

We only provide the const getter version of this operator in order to avoid accidentally setting the value. Use one of the set...() functions explicitily for this.

inline

Set the lookup status for a given char.

Definition at line 126 of file char_lookup.hpp.

set_char_upper_lower()

set_range()

void set_range ( char  first, char  last, T  value  )
