Method Details

get

byte get(long index)

Get an element given its index.

set

byte set(long index,
byte value)

Set a value at the given index and return the previous value.

get

boolean get(long index,
int len,
org.apache.lucene.util.BytesRef ref)

Get a reference to a slice.

Returns:

true when a byte[] was materialized, false otherwise.

set

void set(long index,
byte[] buf,
int offset,
int len)

fill

void fill(long fromIndex,
long toIndex,
byte value)

Fill slots between fromIndex inclusive to toIndex exclusive with value.

hasArray

boolean hasArray()

Checks if this instance is backed by a single byte array analogous to ByteBuffer.hasArray().

array

byte[] array()

Get backing byte array analogous to ByteBuffer.array().
