Constructor & Destructor Documentation

CE_RampCache::CE_RampCache

(

exint

size

)

Initialize the pool with specified maximum size.

CE_RampCache::~CE_RampCache

Member Function Documentation

void CE_RampCache::cacheRamp	(	cl::Buffer	buffer,
		UT_SharedPtr< UT_Ramp >	ramp,
		int	tuplesize,
		int	rampsize
	)

Adds to the cache.

void CE_RampCache::clear

(

)

Empty the memory pool of all held buffers.

exint CE_RampCache::freeMemory

(

exint

amount

)

Attempts to release the requested amount of memory back to the system. Returns the amount actually freed.

void CE_RampCache::getUsage	(	exint &	total,
		exint &	not_in_use
	)		const

Query the current usage; total is the total amount of memory held by the pool, not_in_use is the amount that can be freed immediately on demand.

cl::Buffer CE_RampCache::lookupRamp	(	UT_SharedPtr< UT_Ramp >	ramp,
		int	tuplesize,
		int	rampsize
	)

Returns empty buffer if not in cache. This buffer remains owned by the cache; insofar as calling CE_Context::releaseBuffer.
