RowSequenceAsChunkImpl

public RowSequenceAsChunkImpl()

Method Details

runsUpperBound

protected long runsUpperBound()

asRowKeyChunk

public final LongChunk<OrderedRowKeys> asRowKeyChunk()

Description copied from interface: RowSequence

Get a LongChunk representation of the individual row keys in this RowSequence.

Specified by:

asRowKeyChunk in interface RowSequence

Returns:

A LongChunk containing the row keys in this RowSequence

asRowKeyRangesChunk

public final LongChunk<OrderedRowKeyRanges> asRowKeyRangesChunk()

Description copied from interface: RowSequence

Get a LongChunk representation of row key ranges in this RowSequence.

Specified by:

asRowKeyRangesChunk in interface RowSequence

Returns:

A LongChunk containing the row key ranges in this RowSequence

lastRowKey

public abstract long lastRowKey()

Description copied from interface: RowSequence

Get the last row key in this RowSequence.

Specified by:

lastRowKey in interface RowSequence

Returns:

The last row key, or RowSequence.NULL_ROW_KEY if there is none.

rangesCountUpperBound

public abstract long rangesCountUpperBound()

close

@OverridingMethodsMustInvokeSuper
public void close()

Description copied from interface: RowSequence

Free any resources associated with this object.

Using any RowSequence methods after close() is an error and may produce exceptions or undefined results.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface RowSequence

Specified by:

close in interface SafeCloseable

closeRowSequenceAsChunkImpl

protected final void closeRowSequenceAsChunkImpl()

Close any resources associated with this RowSequenceAsChunkImpl. This is the implementation for close, made available for subclasses that have a need to release parent class resources independently of their own close implementation. Most uses should prefer to invalidate, instead.

invalidateRowSequenceAsChunkImpl

protected final void invalidateRowSequenceAsChunkImpl()
