Detailed Description

This algorithm is designed for applications that jump around between a couple of spots in the cube with a difficult to predict pattern but always the same places in the cube.

This was designed for ProcessMosaic which jumps between band 1 and band n in the possible patterns (where A is a line on band 1 and B is a line on band N): A,A or A,B,A or A,B,B,A

Constructor & Destructor Documentation

◆ BoxcarCachingAlgorithm()

Isis::BoxcarCachingAlgorithm::BoxcarCachingAlgorithm ( )

Construct a new BoxcarCachingAlgorithm.

The last numUniqueIOs will be kept in the cache, while the other chunks in the cache will all be tossed.

◆ ~BoxcarCachingAlgorithm()

Isis::BoxcarCachingAlgorithm::~BoxcarCachingAlgorithm ( )

virtual

Frees the memory allocated by this caching algorithm.

Member Function Documentation

◆ recommendChunksToFree()

CubeCachingAlgorithm::CacheResult Isis::BoxcarCachingAlgorithm::recommendChunksToFree	(	QList< RawCubeChunk * >	allocated,
		QList< RawCubeChunk * >	justUsed,
		const Buffer &	justRequested )

virtual

Please see the class description for how this algorithm works.

Parameters

allocated	All of the allocated cube chunks
justUsed	The cube chunks used in the last I/O
justRequested	The buffer passed into the last I/O

Returns: The chunks that should be removed from memory

Implements Isis::CubeCachingAlgorithm.
