Detailed Description

A singleton that can be used to observe the available libraries in the system.

Note

This singleton doesn't control the libraries lifetime, it just make smart references to them that will be automatically removed when a library goes out of scope (or been destroyed). Actually it works like an observer of known libraries.

This class is based on pimpl idiom.

Member Function Documentation

void te::common::LibraryManager::add	(	const std::string &	id,
		const LibraryPtr &	l
	)
throw	(
	)

It adds a new Library to be managed.

This implementaion will keep the library in the manager while there is at least someone pointing to it. As soon as no one keeps a reference to it the manager will be communicated and the library will not be available anymore.

Parameters

id	An identifier used to search for the library in successive lookups.
l	The library to be managed.

Definition at line 69 of file LibraryManager.cpp.

te::common::LibraryPtr te::common::LibraryManager::find	(	const std::string &	name	)
throw	(
	)

Returns a null pointer if a library doesnt't exist.

Parameters

name	The library name.

Returns

A pointer to an already loaded library or null.

Definition at line 74 of file LibraryManager.cpp.

static LibraryManager & te::common::Singleton< LibraryManager >::getInstance ( )

It returns a reference to the singleton instance.

Returns

A reference to the singleton instance.
