Class SmooksDataFormat

java.lang.Object
  org.milyn.smooks.camel.dataformat.SmooksDataFormat

All Implemented Interfaces:

org.apache.camel.CamelContextAware, org.apache.camel.Service, org.apache.camel.spi.DataFormat

public class SmooksDataFormat
extends java.lang.Object
implements org.apache.camel.spi.DataFormat, org.apache.camel.CamelContextAware, org.apache.camel.Service

SmooksDataFormat is a Camel data format which is a pluggable transformer capable of transforming from one dataformat to another and back again. This means that what is marshaled can be unmarshaled by an instance of this class.

A smooks configuration for a SmooksDataFormat should not utilize Smooks features such as routing that might allocated system resources. The reason for this is that there is no functionality in the SmooksDataFormat which will close those resources. If you need to use these Smooks features please take a look at the SmooksComponent or SmooksProcessor as they hook into Camels lifecycle manegment and will close resources correctly.

Method Detail

marshal

public void marshal(org.apache.camel.Exchange exchange,
                    java.lang.Object fromBody,
                    java.io.OutputStream toStream)
             throws java.lang.Exception

Marshals the Object 'fromBody' to an OutputStream 'toStream'

The Camel framework will call this method from MarshalProcessor.process(Exchange) and it will take care of setting the Out Message's body to the bytes written to the toStream OutputStream.

Specified by:

marshal in interface org.apache.camel.spi.DataFormat

Parameters:

exchange - The Camel Exchange.

fromBody - The object to be marshalled into the output stream.

toStream - The output stream that will be written to.

Throws:

java.lang.Exception

unmarshal

public java.lang.Object unmarshal(org.apache.camel.Exchange exchange,
                                  java.io.InputStream fromStream)
                           throws java.lang.Exception

Unmarshals the fromStream to an Object.

The Camel framework will call this method from UnMarshalProcessor#process(Exchange) and it will take care of setting the returned Object on the Out Message's body.

Specified by:

unmarshal in interface org.apache.camel.spi.DataFormat

Parameters:

exchange - The Camel Exchange.

fromStream - The InputStream that will be unmarshalled into an Object instance.

Throws:

java.lang.Exception

getResult
