Constructor Details

LongColumnSourceWritableRowRedirection

public LongColumnSourceWritableRowRedirection(@NotNull
 @NotNull WritableColumnSource<Long> columnSource)

Method Details

put

public long put(long outerRowKey,
 long innerRowKey)

Description copied from interface: WritableRowRedirection

Add or change a mapping from outerRowKey to innerRowKey.

Specified by:

put in interface WritableRowRedirection

Parameters:

outerRowKey - The outer row key to map from

innerRowKey - The inner row key to map to

Returns:

The inner row key previously mapped from outerRowKey, or RowSequence.NULL_ROW_KEY if there was no mapping

putVoid

public void putVoid(long outerRowKey,
 long innerRowKey)

Description copied from interface: WritableRowRedirection

Like WritableRowRedirection.put(long, long), but without requiring the implementation to provide a return value. May be more efficient in some cases.

Specified by:

putVoid in interface WritableRowRedirection

Parameters:

outerRowKey - The outer row key to map from

innerRowKey - The inner row key to map to

remove

public long remove(long outerRowKey)

Description copied from interface: WritableRowRedirection

Remove a mapping from outerRowKey.

Specified by:

remove in interface WritableRowRedirection

Parameters:

outerRowKey - The outer row key to unmap

Returns:

The inner row key previously mapped from outerRowKey, or RowSequence.NULL_ROW_KEY if there was no mapping

removeVoid

public void removeVoid(long outerRowKey)

Description copied from interface: WritableRowRedirection

Like WritableRowRedirection.remove(long) (long, long)}, but without requiring the implementation to provide a return value. May be more efficient in some cases.

Specified by:

removeVoid in interface WritableRowRedirection

Parameters:

outerRowKey - The outer row key to map from

removeAll

public void removeAll(@NotNull
 @NotNull RowSequence rowSequence)

Description copied from interface: WritableRowRedirection

Remove the specified rowSequence.

Specified by:

removeAll in interface WritableRowRedirection

Parameters:

rowSequence - The outer row keys to remove

removeAllUnordered

public void removeAllUnordered(@NotNull
 @NotNull LongChunk<RowKeys> outerRowKeys)

Description copied from interface: WritableRowRedirection

Remove the specified outerRowKeys.

Specified by:

removeAllUnordered in interface WritableRowRedirection

Parameters:

outerRowKeys - The outer row keys to remove

makeFillFromContext

public ChunkSink.FillFromContext makeFillFromContext(int chunkCapacity)

Description copied from interface: WritableRowRedirection

Make a ChunkSink.FillFromContext for this WritableRowRedirection. The default implementation supplies WritableRowRedirection.DEFAULT_FILL_FROM_INSTANCE, suitable for use with the default implementation of WritableRowRedirection.fillFromChunk(ChunkSink.FillFromContext, Chunk, RowSequence).

Specified by:

makeFillFromContext in interface ChunkSink<RowKeys>

Specified by:

makeFillFromContext in interface WritableRowRedirection

Parameters:

chunkCapacity - The maximum number of mappings that will be supplied in one operation

Returns:

The ChunkSink.FillFromContext to use

fillFromChunk

public void fillFromChunk(@NotNull
 ChunkSink.FillFromContext context,
 @NotNull
 @NotNull Chunk<? extends RowKeys> innerRowKeys,
 @NotNull
 @NotNull RowSequence outerRowKeys)

Description copied from interface: WritableRowRedirection

Insert mappings from each element in a RowSequence to the parallel element in a LongChunk. h

Specified by:

fillFromChunk in interface ChunkSink<RowKeys>

Specified by:

fillFromChunk in interface WritableRowRedirection

Parameters:

context - THe FillFromContext

innerRowKeys - The inner row keys to map to

outerRowKeys - The outer row keys to map from

startTrackingPrevValues

public void startTrackingPrevValues()

Description copied from interface: WritableRowRedirection

Initiate previous value tracking.

Specified by:

startTrackingPrevValues in interface WritableRowRedirection
