Member Function Documentation

DataBlock::generation_type Core::DataBlockManager::get_generation_count

(

)

Get the most recent generation number NOTE: Needed by the project manager when storing the project updates to disk. As within a aproject for provenance and session reasons we cannot use an older generation. The last used number needs to be stored.

DataBlock::generation_type Core::DataBlockManager::increase_generation

(

DataBlock::generation_type

old_generation

)

Generate a new generation number for a datablock. This function is called through the DataBlock class whenever the data in a datablock is changed.

void Core::DataBlockManager::register_datablock	(	DataBlockHandle	data_block,
		DataBlock::generation_type	generation = -1
	)

This function needs to be called by the various datablock factories. So we can look up in this DataBlock manager whether a datablock has already been loaded (needed for the mask data)

void Core::DataBlockManager::set_generation_count

(

DataBlock::generation_type

generation

)

Set the current count in the generation counter NOTE: This is needed when loading an existing project, as each project has its own generation count.
