Constructor Detail

### TransformerChain

    public TransformerChain(List<Transformer> transformers)

### TransformerChain

    public TransformerChain(Transformer... transformers)

### TransformerChain

    public TransformerChain(String name,
                            List<Transformer> transformers)

### TransformerChain

    public TransformerChain(String name,
                            Transformer... transformers)

Method Detail

### transformMessage

    public Object transformMessage(MuleMessage message,
                                   String outputEncoding)
                            throws TransformerException

  Description copied from class: `AbstractMessageTransformer`
  Transform the message

  Specified by:
    `transformMessage` in class `AbstractMessageTransformer`
  Returns:
  Throws:
    `TransformerException`

### initialise

    public void initialise()
                    throws InitialisationException

  Description copied from class: `AbstractTransformer`
  Template method where deriving classes can do any initialisation after the properties have been set on this transformer

  Specified by:
    `initialise` in interface `Initialisable`
  Overrides:
    `initialise` in class `AbstractTransformer`
  Throws:
    `InitialisationException` - if a fatal error occurs causing the Mule instance to shutdown
    `RecoverableException` - if an error occurs that can be recovered from

### setMuleContext

    public void setMuleContext(MuleContext muleContext)

  Specified by:
    `setMuleContext` in interface `MuleContextAware`
  Overrides:
    `setMuleContext` in class `AbstractTransformer`

### setEndpoint

    public void setEndpoint(ImmutableEndpoint endpoint)

  Description copied from interface: `BaseTransformer`
  Sets the endpoint associated with with this connector. This should be idempotent, since endpoints do not guarantee it will only be called once.

  Specified by:
    `setEndpoint` in interface `BaseTransformer`
  Overrides:
    `setEndpoint` in class `AbstractTransformer`
  Parameters:
    `endpoint` - sets the endpoint associated with the transfromer

### generateTransformerName

    protected String generateTransformerName()

  Overrides:
    `generateTransformerName` in class `AbstractTransformer`
