Method Details

getInt

public int getInt(long rowKey)

Description copied from interface: ColumnRegionInt

Get a single int from this region.

Specified by:

getInt in interface ColumnRegionInt<ATTR extends Any>

Parameters:

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

Returns:

The int value at the specified element row key

getPageContaining

@NotNull
public final @NotNull ChunkHolderPageInt<ATTR> getPageContaining(@Nullable
 @Nullable ChunkSource.FillContext fillContext,
 long rowKey)

Specified by:

getPageContaining in interface PageStore<ATTR extends Any,ATTR extends Any,ChunkHolderPageInt<ATTR extends Any>>

Parameters:

fillContext - The fill context to use; may be null if the calling code does not have a fill context

rowKey - The row key to get the page for

Returns:

The page containing rowKey, after applying PagingChunkSource.mask().
