int StarBlockFactory::freeAll ( )

inline

Frees all StarBlocks that are in the cache.

Returns

The number of StarBlocks freed

int StarBlockFactory::freeUnused

(

)

Frees all StarBlocks that are not used in this draw cycle.

Returns

The number of StarBlocks freed

StarBlock * StarBlockFactory::getBlock

(

)

Return a StarBlock available for use.

This method first checks if there are any cached StarBlocks that are not in use. If such a StarBlock is found, it returns the same for use. Else it freshly allocates a StarBlock and returns the same. It also moves the StarBlock to the front, marking it as the most recently used. If the StarBlock had a parent StarBlockList, this method detaches the StarBlock from the StarBlockList

Returns

A StarBlock that is available for use

Definition at line 49 of file starblockfactory.cpp.

int StarBlockFactory::getBlockCount ( )

inline

Returns the number of StarBlocks currently produced.

Returns

Number of StarBlocks currently allocated

bool StarBlockFactory::markFirst

(

StarBlock *

block

)

Mark a StarBlock as most recently used and sync its drawID with the current drawID.

bool StarBlockFactory::markNext	(	StarBlock *	after,
		StarBlock *	block
	)

Rank a given StarBlock after another given StarBlock in the LRU list and sync its drawID with the current drawID.

Parameters

after	The block after which 'block' should be put
block	The block to mark for use

Returns

true on success, false on failure
