Method Details

mask

@FinalDefault default long mask()

Description copied from interface: PagingChunkSource

This mask is applied to OrderedKeys which are passed into ChunkSource.getChunk(ChunkSource.GetContext, OrderedKeys) and ChunkSource.fillChunk(ChunkSource.FillContext, WritableChunk, OrderedKeys). This allows the PagingChunkSources to be cached, and reused even if they are properly relocated in key space.

Specified by:

mask in interface PagingChunkSource<ATTR extends Attributes.Any>

Returns:

the mask for this page, which must be a bitmask representing the some number of lower order bits of a long.

firstRowOffset

@FinalDefault default long firstRowOffset()

Specified by:

firstRowOffset in interface Page<ATTR extends Attributes.Any>

Returns:

the first row of this page, after applying the PagingChunkSource.mask(), which refers to the first row of this page.
