Profiler & gpucalc::Profiler::getSingleton

(

)

[static]

Override standard Singleton retrieval.

Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

Reimplemented from gpucalc::Singleton< T >.

void gpucalc::Object::getSpecificParameter	(	const std::string &	ParameterName,
		void *	ParameterValue
	)			[inline, inherited]

Method for obtaining some specific parameters, such as texture specific params, and so on.

Parameters:

	ParameterName	- name of parameter, usually it similar to specific method of some object (for example, GLTextureID)
	ParameterValue	- contain value of named parameter, it must be allocated and have sufficient size.

Todo:

Think for better realization.

bool gpucalc::Object::isLocked

(

)

const [inline, inherited]

returns state of object.

If object is locked then we cannot change some state of it, because object is used in computation. If object is unlocked then we can change some state of it, object is not in computation.
