All Implemented Interfaces:

FudgeBuilderFactory

public class FudgeBuilderFactoryAdapter
extends Object
implements FudgeBuilderFactory

Implementation of a FudgeBuilderFactory that can delegate to another instance for unrecognized classes. This pattern is to allow factories to be chained together.

Constructor Summary

protected

FudgeBuilderFactoryAdapter(FudgeBuilderFactory delegate) Creates a new FudgeBuilderFactoryAdapter.

Method Summary

<T> void	addGenericBuilder(Class<T> clazz, FudgeBuilder<T> builder) Registers a generic builder with the factory that may be returned as a FudgeObjectBuilder for the class, or as a FudgeMessageBuilder for any sub-classes of the class.
<T> FudgeMessageBuilder<T>	createMessageBuilder(Class<T> clazz) Creates a new FudgeMessageBuilder for encoding objects of the given class into Fudge messages.
<T> FudgeObjectBuilder<T>	createObjectBuilder(Class<T> clazz) Creates a new FudgeObjectBuilder for deserializing Fudge messages into the given class.
protected FudgeBuilderFactory	getDelegate() Returns the delegate instance to pass method calls to.

addGenericBuilder

public <T> void addGenericBuilder(Class<T> clazz,
                                  FudgeBuilder<T> builder)

Registers a generic builder with the factory that may be returned as a FudgeObjectBuilder for the class, or as a FudgeMessageBuilder for any sub-classes of the class. After calling this, a factory may choose to return an alternative builder, but may not return null for a class which the generic builder has been registered for.

Specified by:

addGenericBuilder in interface FudgeBuilderFactory

Type Parameters:

T - the generic type (probably an interface) the builder is for

Parameters:

clazz - the generic type (probably an interface) the builder is for

builder - the builder to register

createMessageBuilder

public <T> FudgeMessageBuilder<T> createMessageBuilder(Class<T> clazz)

Creates a new FudgeMessageBuilder for encoding objects of the given class into Fudge messages.

Specified by:

createMessageBuilder in interface FudgeBuilderFactory

Type Parameters:

T - the class the builder should create messages from

Parameters:

clazz - the class the builder should create messages from

the builder or null if none is available

createObjectBuilder

public <T> FudgeObjectBuilder<T> createObjectBuilder(Class<T> clazz)

Creates a new FudgeObjectBuilder for deserializing Fudge messages into the given class.

Specified by:

createObjectBuilder in interface FudgeBuilderFactory

Type Parameters:

T - the class the builder should create objects of

Parameters:

clazz - the class the builder should create objects of
