Method Detail

size

public int size()

Description copied from interface: Bytes

Returns number of bytes in this Bytes.

Returns:

number of bytes in this Bytes

byteAt

public byte byteAt(int index)

Description copied from interface: Bytes

Returns byte at the specified index.

Parameters:

index - (zero-based) index

Returns:

byte at the specified index

toByteArray

public byte[] toByteArray()

Description copied from interface: Bytes

Converts this Bytes to array of bytes. This operation always copying and allocation of a new byte array.

Returns:

new array containing data of this Bytes.

toReadOnlyByteBuffer

public java.nio.ByteBuffer toReadOnlyByteBuffer()

Description copied from interface: Bytes

Converts this Bytes to read-only. ByteBuffer. This operation will involve allocation and copying unless the implementation is backed by ByteBuffer.

Returns:

read-only ByteBuffer containing data of this Bytes

toString

public java.lang.String toString(java.nio.charset.Charset charset)

Description copied from interface: Bytes

Converts this Bytes to String in the specified charset. This operation has the same characteristics in terms of allocation and copying as Bytes.toByteArray()

Parameters:

charset - charset to be used when decoding the bytes

Returns:

String decoded from the bytes

newInputStream

public java.io.InputStream newInputStream()

Description copied from interface: Bytes

Returns new InputStream that reads data contained in this Bytes.

Returns:

new InputStream that reads data contained in this Bytes

view

public Bytes view(int beginIndex,
                  int endIndex)

Description copied from interface: Bytes

Returns Bytes that is a view into this one. The view begins at the specified beginIndex and extends to the byte at index endIndex - 1. Thus the length of the view is endIndex-beginIndex.

Parameters:

beginIndex - the beginning index, inclusive

endIndex - the ending index, exclusive

Returns:

the specified view

wrap

public static ConcatBytes wrap(Bytes bytes1,
                               Bytes bytes2,
                               Bytes... bytesN)

Wraps existing instances of Bytes and concatenates them.

Returns:

new ConcatBytes wrapping the specified Bytes instances

wrap

public static ConcatBytes wrap(java.util.List<Bytes> bytesN)

Wraps existing instances of Bytes and concatenates them.

Returns:

new ConcatBytes wrapping the specified Bytes instances
