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

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.

Parameters

numUniqueIOs

The number of unique IO operations to keep the chunks around for.

Definition at line 42 of file BoxcarCachingAlgorithm.cpp.

Isis::BoxcarCachingAlgorithm::~BoxcarCachingAlgorithm ( )

virtual

Frees the memory allocated by this caching algorithm.

Member Function Documentation

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
