Class LoopbackTransformer

(package private)  int delegateBlockSize()

Overrides:

delegateBlockSize in interface Transformer

public void init(Map attributes)
            throws TransformerException

Initialises the Transformer for operation with specific characteristics.

Overrides:

init in interface Transformer

Parameters:

attributes - a set of name-value pairs that describes the desired future behaviour of this instance.

(package private)  void initDelegate(Map attributes)
            throws TransformerException

Overrides:

initDelegate in interface Transformer

public byte[] lastUpdate()
            throws TransformerException

Convenience method that calls the same method with three arguments. A zero-long byte array is used.

Overrides:

lastUpdate in interface Transformer

Returns:

the result of transformation.

Throws:

TransformerException - if a transformation-related exception occurs during the operation.

See Also:

Transformer.lastUpdate(byte[],int,int)

(package private)  byte[] lastUpdateDelegate()
            throws TransformerException

Overrides:

lastUpdateDelegate in interface Transformer

public void reset()

Resets the Transformer for re-initialisation and use with other characteristics. This method always succeeds.

Overrides:

reset in interface Transformer

(package private)  void resetDelegate()

Overrides:

resetDelegate in interface Transformer

public byte[] update(byte[] in,
                     int offset,
                     int length)
            throws TransformerException

Processes a designated number of bytes from a given byte array.

Overrides:

update in interface Transformer

Parameters:

in - the input data bytes.

offset - index of in from which to start considering data.

length - the count of bytes to process.

Returns:

the result of transformation.

Throws:

TransformerException - if a transformation-related exception occurs during the operation.

(package private)  byte[] updateDelegate(byte[] in,
                                         int offset,
                                         int length)
            throws TransformerException
