explicit ctype (size_t refs=0);
ctype constructor
Constructs a ctype facet object.
Calls the constructor of its base class locale::facet.
Parameters
- refs
- 0 (zero) if the object has to be automatically destroyed when the last locale containing that facet is destroyed, or 1 (one) if it will be explicitly deleted.
size_t is an unsigned integral type.
Specialization for ctype<char>
The ctype class is specialized for the char type. This specialization has a different constructor with additional parameters:
| |
explicit ctype ( const mask* tab = 0, bool del = false, size_t refs = 0 );
|
The additional parameters in this specialization represent:
- tab
- Pointer to an array containing a table with the classification of each of the characters in the character set (as if returned by the array version of ctype::is). Or zero, if the classic table (a predefined table) is to be used.
ctype::mask is a bitmask member type.
- del
- If true, the destructor will automatically delete the table passed as first argument, so that the program needs not to care about the facet's lifetime.
