ChunkGenerator()

ChunkGenerator::ChunkGenerator ( Addr  _startAddr, Addr  totalSize, Addr  _chunkSize  )

inline

Constructor.

Parameters

_startAddr	The starting address of the region.
totalSize	The total size of the region.
_chunkSize	The size/alignment of chunks into which the region should be decomposed.

complete()

Addr ChunkGenerator::complete ( ) const

inline

Number of bytes we have already chunked up.

done()

bool ChunkGenerator::done ( ) const

inline

Are we done? That is, did the last call to next() advance past the end of the region?

Returns

True if yes, false if more to go.

last()

bool ChunkGenerator::last ( ) const

inline

Is this the last chunk?

Returns

True if yes, false if more to go.

next()

bool ChunkGenerator::next ( )

inline

Advance generator to next chunk.

Returns

True if successful, false if unsuccessful (because we were at the last chunk).

setNext()

void ChunkGenerator::setNext ( Addr  next )

inline

Grow this chunk to cover additional bytes which are already handled.

Parameters

next	The first byte of the next chunk.
