public class SerializeTransformer
extends AbstractTransformer

Standard Java Serialization transformation from Serializable Object to byte[]. If a FastByteArrayOutputStream is provided on top of the Object, then the Object is serialized into the given OutputStream instead of using a temporary ObjectOutputStream. In this case, the resulting context stack contains the number of bytes of the resulting byte[] size, and then the byte[] itself. In the case of the FastByteArrayOutputStream, the byte[] is shared, not copied.

public SerializeTransformer()
Method Detail

transform

public void transform(Envelope env)
               throws java.lang.Exception
Serialize an object. The Envelope's context stack contains either a serializable object, or a FastByteArrayOutputStream and a serializable object ( in that order ) for serialization to be successful. The resulting byte[] is placed on the context stack.

Specified by:
transform in interface Transformer
Specified by:
transform in class AbstractTransformer
Parameters:
env - the Envelope containing data to transform and the result.
Throws:
java.lang.Exception - if a failure condition occcurs.

configure

public void configure(java.lang.String name,
                      Properties props)
               throws java.lang.Exception
Configure the SerializableTransformer.

The following configuration attributes are defined in addition to those of the superclass:

Specified by:
configure in interface Configurable
Overrides:
configure in class AbstractTransformer
Parameters:
name - the fully qualified instance name.
props - the read-only properties to configure the instance with.
Throws:
java.lang.Exception - when configuration is unsuccessful.
