Method Details

mask

public final long mask()

Description copied from interface: PagingChunkSource

This mask is applied to RowSequences which are passed into DefaultChunkSource.getChunk(io.deephaven.engine.table.ChunkSource.GetContext, io.deephaven.engine.rowset.RowSequence), ChunkSource.fillChunk(io.deephaven.engine.table.ChunkSource.FillContext, io.deephaven.chunk.WritableChunk<? super ATTR>, io.deephaven.engine.rowset.RowSequence), and PagingChunkSource.fillChunkAppend(FillContext, WritableChunk, RowSequence.Iterator) . This allows PagingChunkSources to be cached and reused even if they are properly relocated in key space.

Specified by:

mask in interface PagingChunkSource<ATTR extends Any>

Returns:

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

invalidate

public void invalidate()

Description copied from interface: ColumnRegion

Invalidate the region -- any further reads that cannot be completed consistently and correctly will fail.

Specified by:

invalidate in interface ColumnRegion<ATTR extends Any>

throwIfInvalidated

protected final void throwIfInvalidated()
