com.kuka.comm.codec
Class SwitchEncoder<I,O>

java.lang.Object
  com.kuka.comm.codec.Encoder<I,O>
      com.kuka.comm.codec.SwitchEncoder<I,O>

Type Parameters:

I - The input message of type I.

O - The resulting output of type O.

public final class SwitchEncoder<I,O>
extends Encoder<I,O>

Class to determine the encoder according to the type of message which should be send. This class ensures a type-safe identification of the associated encoder as long as an encoder for this message type exists.

This class won't encode anything directly. It is rather an selector for the right encoder. The encode method will be used to call the encode method of the chosen encoder.

addEncoder

public <T extends I> SwitchEncoder<I,O> addEncoder(Class<? extends T> inputType,
                                                   Encoder<T,O> encoder)
                              throws IllegalArgumentException

Public method to add an encoder to a list of encoder.

Analyzes the given encoder interface to identify its class and stores them in an internal map.

Type Parameters:

T - the input type

Parameters:

inputType - the type of the input of the given encoder

encoder - an encoder interface to append to internal encoder map

Returns:

this-pointer to this object.

Throws:

IllegalArgumentException - An exception thrown if no encoder-type could be resolved.

encodeImpl

protected void encodeImpl(I in,
                          O out)
                   throws EncoderException

Description copied from class: Encoder

Override this method to implement encoding process.

Note: You should override either this method or Encoder.encodeImpl(Object, Object, EncoderContext). Overriding both will have no effect, i.e. only Encoder.encodeImpl(Object, Object, EncoderContext) will be called.

Overrides:

encodeImpl in class Encoder<I,O>

Parameters:

in - the input for this encoder

out - the output for this encoder

Throws:

EncoderException - if an error occurred during encoding
