 @NotNull
 @NotNull AppendOnlyRegionAccessor<ATTR> accessor)

Method Details

getObject

public T getObject(long rowKey)

Description copied from interface: ColumnRegionObject

Get a single object from this region.

Specified by:

getObject in interface ColumnRegionObject<T,ATTR extends Any>

Parameters:

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

Returns:

The object value at the specified element row key

getPageContaining

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

Specified by:

getPageContaining in interface PageStore<ATTR extends Any,ATTR extends Any,ChunkHolderPageObject<T,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().
