Detailed Description

This interface represents a stream source.

This can be implemented by the application to implement faster loading of data. Basically the idea is to have some kind of 'id' that represents a buffer for a mesh. This implementation of this interface can try to load the buffer given that id.

Member Function Documentation

virtual bool iStreamSource::QueryBuffer	(	const char *	id,
		iStreamDataCallback *	callback
	)			[pure virtual]

Load a buffer given an id.

This will fire the callback as soon as the buffer is ready. Note that some implementations that don't support asynchronious loading may call the callback immediatelly from within this function.

Returns:

false if we can't find the buffer (early error). The error should be placed on the reporter.

virtual bool iStreamSource::SaveBuffer	(	const char *	id,
		iDataBuffer *	buffer
	)			[pure virtual]

Save a buffer with some id.

Returns false if the buffer couldn't be saved for some reason. The error should be reported on the reporter by this function.
