Constructor Detail

KeyConverterAdapter

public KeyConverterAdapter(KeyConverter converter)

Construct KeyConverterAdapter instance.

Parameters:

converter - key converter used to marshall key objects

Method Detail

marshal

public void marshal(java.lang.Object oValue,
                    java.io.OutputStream out)
             throws java.io.IOException

Write the specified object into the given stream.

Specified by:

marshal in interface Marshaller

Parameters:

oValue - object to marshall

out - stream to write to

Throws:

java.io.IOException - if an error occurs during marshalling

marshalAsFragment

public void marshalAsFragment(java.lang.Object oValue,
                              java.io.OutputStream out)
                       throws java.io.IOException

Write the specified object into the given stream as a fragment.

This method is called when marshalling collections of objects, as marshalling behavior might differ when an object is serialized directly or as element of a collection.

For example, when marshalling a collection of objects into XML, you need to ensure that the XML declaration is emmitted only once, not for each object in the collection.

In cases where there is no difference in output between fragments and full objects (JSON, for example), this method could simply delegate to Marshaller.marshal(Object, OutputStream).

Specified by:

marshalAsFragment in interface Marshaller

Parameters:

oValue - object to marshall

out - stream to write to

Throws:

java.io.IOException - if an error occurs during marshalling

unmarshal

public java.lang.Object unmarshal(java.io.InputStream in)
                           throws java.io.IOException

Read an object from the specified stream.

Specified by:

unmarshal in interface Marshaller

Parameters:

in - stream to read from

Returns:

unmarshalled object instance

Throws:

java.io.IOException - if an error occurs during unmarshalling
