Method Details

getDouble

double getDouble(long elementIndex)

Get a single double from this region.

Parameters:

elementIndex - Element row key in the table's address space

Returns:

The double value at the specified element row key

getDouble

default double getDouble(@NotNull
 @NotNull ChunkSource.FillContext context,
 long elementIndex)

Get a single double from this region.

Parameters:

context - A PagingContextHolder to enable resource caching where suitable, with current region index pointing to this region

elementIndex - Element row key in the table's address space

Returns:

The double value at the specified element row key

getChunkType

@FinalDefault
default ChunkType getChunkType()

Description copied from interface: ChunkSource

Specified by:

getChunkType in interface ChunkSource<ATTR extends Any>

Returns:

The ChunkType
