Method Details

pageWrap

public static <ATTR extends Attributes.Any> ShortChunkPage<ATTR> pageWrap(long beginRow, short[] data, int offset, int capacity, long mask)

pageWrap

public static <ATTR extends Attributes.Any> ShortChunkPage<ATTR> pageWrap(long beginRow, short[] data, long mask)

getNativeType

public Class<Short> getNativeType()

Specified by:

getNativeType in interface ChunkSource<ATTR extends Attributes.Any>

fillChunkAppend

public final void fillChunkAppend(@NotNull ChunkSource.FillContext context, @NotNull WritableChunk<? super ATTR> destination, @NotNull OrderedKeys orderedKeys)

Description copied from interface: Page.WithDefaults

Appends the values referenced by orderKeys onto destination. orderKeys are assumed to be entirely contained on this Page.

Specified by:

fillChunkAppend in interface Page.WithDefaults<ATTR extends Attributes.Any>

firstRowOffset

public final 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.

mask

public final 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.
