Class PolicySerializerDeSerializerFactory

java.lang.Object
oracle.wsm.policy.util.PolicySerializerDeSerializerFactory

public class PolicySerializerDeSerializerFactory

extends Object

This class maintains a Map of the Serializer/DeSerializers to be used for serializing/de-serializing a Policy. It provides a plug-in framework to support custom assertion development. Currently the framework is DOM based. The framework currently does not allow overriding serializer/de-serializers for some of the standard elements like wsp:Policy, wsp:All, wsp:ExactlyOne, wsp:PolicyAttachment, orawsp:PolicySet, etc. The framework has the concept of a default Seralizer/DeSerializer. One of the goals of the framework is to reduce the need for writing Serializer/De-Serializers where possible. To faciliate this aspect, the framework defines the concept of Default Serializer/De-Serializer. The "Default" Serializer/De-Serializer can be used when Assertions follow a particular pattern. The framework defines different types of Assertions. These can be currently categorized into the following:

1. Simple Assertions ISimpleAssertion
2. Nested Assertions INestedAssertion
3. Composite Assertions ICompositeAssertion
4. Scenario Assertions IScenarioAssertion
5. Step Scenario Assertions oracle.wsm.policy.model.IStepScenarioAssertion
6. Policy IPolicy
7. PolicyReference IPolicyReference

IAssertion for more details. The Default Serializer/De-Serializer can be used when Assertions are either of type ISimpleAssertion or of type INestedAssertion. Example: Most assertions specified in the WS-SecurityPolicy spec fall into this category. Custom Assertion Development and Serialization/De-Serialization:

• If Custom Assertions fall into the patterns represented by ISimpleAssertion or by INestedAssertion then you do not have to write a Serializer/De-Serializer.
• It is expected that most Custom Assertion will extend the IScenarioAssertion interface. In this case Custom Assertion developers will have to write their own Serializer/De-Serializers.
