Detailed Description
template<class T>
class eq::util::ObjectManager< T >
A facility class to manage OpenGL objects across shared contexts.
The object manager implements object sharing in the same way as OpenGL. During creation, a shared object manager may be given, causing the two (or more) object managers to allocate objects from the same namespace. The last object manager will delete all data allocated on the host. OpenGL objects have to be explictly deleted using deleteAll() to ensure an OpenGL context is still current during destruction.
For each type of OpenGL object supported the following methods are available:
- supportsObject: Check if the necessary OpenGL version or extension is present
- getObject: Lookup an existing object, may return 0
- newObject: Allocate new object, returns false if key exists
- obtainObject: Lookup or allocate an object for the given key
- deleteObject: Delete the object of the given key and all associated OpenGL data
