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.

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:

• size - integer[1..MAX-INT] - optional[1024].

  The size for pre-sizing the output stream buffer allocated if FastByteArrayOutputStream is not used.

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.
