Detailed Description

Class Repository is a wrapper on a std::map that holds Instanciators accessed by string keys.

It creates the default std::map when constructed, new algorithm can be inserted at runtime, and destroys the it at the end of its lifetime.

Member Function Documentation

void halftoner::HalftonerFactory::Repository::add (  const char *    name, const Instanciator *    instanciator )  throw (std::invalid_argument)

Adds a new algorithm at runtime. Parameters: name  the name of the new algorithm, it must be unique. instanciator  the object creating new instance of the algorithm. Exceptions: std::invalid_argument  if an algorithm with the same name has already been added. Definition at line 140 of file HalftonerFactory.cxx. Referenced by halftoner::HalftonerFactory::addHalftoner().

const Instanciator * halftoner::HalftonerFactory::Repository::get (  const char *    key )  throw ()

Returns the requested Instanciator. Parameters: key  the key attached to the algorithm. Returns : an Instanciator capable of instanciating a new algorithm object, 0 if the key does not map.

std::map< const char *, const Instanciator * > & halftoner::HalftonerFactory::Repository::getMap (    )  throw () [private]

Gets the map. Returns : the underlying map. Definition at line 130 of file HalftonerFactory.cxx.
