public class DefaultMarshaller

extends SourceMarshaller

Marshals a JavaBean by looking for get/set or get/is method pairs. The DefaultMarshaller will normally only marshal an Object if no other marshaller has indicated that it can handle that Object.

DefaultMarshaller()

Method Summary

boolean	doesMarshal(Object object) Returns true for all non-null Objects.
protected Object	getJustInitializedObjectOfType(MarshallingContext context, String objectType) Create a newly instantiated Object of the requested type, or get one out of the "justInitializedObjectMap".
String	marshal(ChainOfResponsibility chainOfResponsibility, MarshallingContext context, ClassSource classSource, Object object, boolean marshalAsObject) Marshals the given object into the given classSource, adding new methods to the classSource as required and returning a String that will be put inside a setter call or used in a return.

Method Detail

doesMarshal

public boolean doesMarshal(Object object)

Returns true for all non-null Objects. The DefaultMarshaller is, by default, the last marshaller to get a chance to marshal an Object. The NullMarshaller is, by default, the first marshaller to get a chance to marshal an Object, so normally the given object would not be null here. The test is a guard clause which will, under all normal circumstances, never be triggered.

                      ClassNotFoundException,
                      InstantiationException

Marshals the given object into the given classSource, adding new methods to the classSource as required and returning a String that will be put inside a setter call or used in a return. This method will return either the source code to pull an already seen Object out of the alreadySeen map, or a method call that will return the required Object for use in a setter call or return statement.

getJustInitializedObjectOfType

protected Object getJustInitializedObjectOfType(MarshallingContext context,
                                                String objectType)
                                         throws ClassNotFoundException,
                                                IllegalAccessException,
                                                InstantiationException

Create a newly instantiated Object of the requested type, or get one out of the "justInitializedObjectMap". The returned Object can then be compared to an Object about to be marshalled to cut down on unneeded setter calls.

Parameters:

context - the "justInitializedObjectMap" from the context is used to instantiate each type only once

objectType - the fully qualified class name to instantiate, which must have a public, no-args constructor.

Returns:

a newly instantiated Object of the requested type

Throws:

ClassNotFoundException

IllegalAccessException

InstantiationException
