Class FixedLengthByteIterable

java.lang.Object

jetbrains.exodus.ByteIterableBase

jetbrains.exodus.FixedLengthByteIterable

All Implemented Interfaces:

java.lang.Comparable<ByteIterable>, ByteIterable

public class FixedLengthByteIterable
extends ByteIterableBase

Helps to create new ByteIterable as a part of another (source) ByteIterable. Is used in basic implementation of ByteIterable.subIterable(int, int).

Method Detail

getBytesUnsafe

public byte[] getBytesUnsafe()

Specified by:

getBytesUnsafe in interface ByteIterable

Overrides:

getBytesUnsafe in class ByteIterableBase

Returns:

raw content of the ByteIterable. May return array with length greater than ByteIterable.getLength().

getOffset

public int getOffset()

getLength

public int getLength()

Specified by:

getLength in interface ByteIterable

Overrides:

getLength in class ByteIterableBase

Returns:

length of the ByteIterable.

subIterable

@NotNull
public @NotNull ByteIterable subIterable(int offset,
                                                  int length)

Specified by:

subIterable in interface ByteIterable

Overrides:

subIterable in class ByteIterableBase

Parameters:

offset - start offset, inclusive

length - length of the sub-iterable

Returns:

a fixed-length sub-iterable of the ByteIterable starting from offset.

getSource

public ByteIterable getSource()

Overrides:

getSource in class ByteIterableBase

getIterator

protected ByteIterator getIterator()

Specified by:

getIterator in class ByteIterableBase
