Member Function Documentation

Add()

virtual void libCZI::ISubBlockCacheOperation::Add ( int  subblock_index, std::shared_ptr< IBitmapData >  pBitmap  )

pure virtual

Adds the specified bitmap for the specified subblock_index to the cache. If the subblock is already in the cache, then it is overwritten.

Parameters

subblock_index	The subblock index to add.
pBitmap	The bitmap.

Get()

virtual std::shared_ptr<IBitmapData> libCZI::ISubBlockCacheOperation::Get ( int  subblock_index )

pure virtual

Gets the bitmap for the specified subblock-index. If the subblock is not in the cache, then a nullptr is returned.

Parameters

subblock_index

The subblock index to get.

Returns

If the subblock is in the cache, then a std::shared_ptr<libCZI::IBitmapData> is returned. Otherwise a nullptr is returned.
