Detailed Description

The namespace for utility constructs.

Bug:

FIXME: utility::limits should be removed, or std::numeric_limits should not be used/specialized.

Function Documentation

std::ostream & operator<< (  std::ostream &  o, std::pair< U, V >  p )

To display a single pair It assumes that each element of the pair is printable (i.e. the operator << is defined on it) Definition at line 56 of file couple_letter.hxx.

escaper< T > make_escaper (  const T &  w  )

Build an escaper. See also: escaper, setesc, getesc(), iomanip. Author: Thomas Claveirole <thomas.claveirole@lrde.epita.fr> Definition at line 77 of file escaper.hxx. Referenced by DumpVisitor::constant(), vcsn::op_rout(), and std::operator<<().

std::set< char > & getesc (  std::ostream &  ostr  )  [inline]

Retrieve the escaped characters set of a stream. See also: escaper, setesc, iomanip. Author: Thomas Claveirole <thomas.claveirole@lrde.epita.fr> Definition at line 111 of file escaper.hxx. References escaped(), and vcsn::tools::usual_escaped_characters(). Referenced by escaper::operator()().

void pword_delete (  std::ios_base::event  ev, std::ios_base &  io, int  idx )

Delete memory associated with a stream upon its destruction. Some manipulators allocate memory and use the internal extensible array to store pointers to the allocated zone. Upon the stream's destruction, the memory must be freed to avoid memory leaks. This function is a generic callback that will perform such a destruction. idx is used as an index in the internal extensible array to an element of type T*. When an erase_event is received, the element idx refers to in the stream is deleted. Parameters: T  Type of the pointed element. ev IO event. io Related stream. idx Index in the internal extensible array of a pointer to delete. See also: iomanip Author: Thomas Claveirole <thomas.claveirole@lrde.epita.fr> Definition at line 57 of file iomanip.hxx.
