Method Details

append

public void append(org.apache.lucene.util.BytesRef key)

get

public org.apache.lucene.util.BytesRef get(long id,
 org.apache.lucene.util.BytesRef dest)

Return the key at 0 <= index <= capacity(). The result is undefined if the slot is unused.

Beware that the content of the BytesRef may become invalid as soon as close() is called

size

public long size()

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface Releasable

takeOwnershipOf

public static BytesRefArray takeOwnershipOf(BytesRefArray other)

Create new instance and pass ownership of this array to the new one. Note, this closes this array. Don't use it after passing ownership.

Parameters:

other - BytesRefArray to claim ownership from

Returns:

a new BytesRefArray instance with the payload of other

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

IOException

ramBytesUsed

public long ramBytesUsed()

Specified by:

ramBytesUsed in interface org.apache.lucene.util.Accountable
