Method Detail

compareTo

public int compareTo(ByteIterable right)

Specified by:

compareTo in interface java.lang.Comparable<ByteIterable>

iterator

public ByteIterator iterator()

Specified by:

iterator in interface ByteIterable

getBytesUnsafe

public byte[] getBytesUnsafe()

Specified by:

getBytesUnsafe in interface ByteIterable

Returns:

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

getLength

public int getLength()

Specified by:

getLength in interface ByteIterable

Returns:

subIterable

@NotNull
public @NotNull ByteIterable subIterable(int offset,

Specified by:

subIterable in interface ByteIterable

Parameters:

offset - start offset, inclusive

length - length of the sub-iterable

Returns:

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