Class AbstractGeneratorAdapterFactory

java.lang.Object
  org.eclipse.emf.common.notify.impl.AdapterFactoryImpl
      org.eclipse.emf.codegen.ecore.generator.AbstractGeneratorAdapterFactory

All Implemented Interfaces:

GeneratorAdapterFactory, AdapterFactory

public abstract class AbstractGeneratorAdapterFactory
extends AdapterFactoryImpl
implements GeneratorAdapterFactory

A base GeneratorAdapterFactory implementation. Classes that extend this implementation need only implement createAdapter(Notifier) and dispose().

An alternate approach to implementing GeneratorAdapterFactory is to extend the adapter factory generated for a package. GeneratorAdapterFactory's overrides of isFactoryForType(Object) and adapt(Notifier, Object) should be duplicated in classes that take such an approach.

Since:

2.2.0

Method Summary

Adapter	adapt(Notifier target, java.lang.Object type) Does an adapt(Notifier, Object), substituting this for the given type.
protected abstract Adapter	createAdapter(Notifier target) Override this to create the adapter for a Notifier.
protected Adapter	createAdapter(Notifier target, java.lang.Object type) Calls createAdapter(Notifier) to create an adapter for the given Notifier and sets its adapter factory to this.
protected GeneratorAdapter	createAdapter(java.lang.Object object) The given object is returned if it is, itself, a GeneratorAdapter.
protected java.lang.Object	createAdapter(java.lang.Object object, java.lang.Object type) Calls createAdapter(Object) to create an adapter for the given object and sets its adapter factory to this.
abstract void	dispose() Disposes this adapter factory and all of the adapters it has created.
Generator	getGenerator() Returns the Generator associated with this adapter factory.
void	initialize(java.lang.Object input) Performs initialization for the given model-level input object.
boolean	isFactoryForType(java.lang.Object type) Returns true when the type is GeneratorAdapter.class.
protected java.lang.Object	resolve(java.lang.Object object, java.lang.Object type) There's no general way to check if a non-Notifier already has an adapter associated with it, but in cases where there is a way, override this method and do it here.
void	setGenerator(Generator generator) Sets the Generator associated with this adapter factory.

Method Detail

isFactoryForType

public boolean isFactoryForType(java.lang.Object type)

Returns true when the type is GeneratorAdapter.class.

Specified by:

isFactoryForType in interface AdapterFactory

Overrides:

isFactoryForType in class AdapterFactoryImpl

Parameters:

type - the key indicating the type of adapter in question.

Returns:

false.

See Also:

Adapter.isAdapterForType(java.lang.Object)

adapt

public Adapter adapt(Notifier target,
                     java.lang.Object type)

Does an adapt(Notifier, Object), substituting this for the given type. This substitution is necessary because each of many generator adapter factories can have its own generator adapter on a single object.

Specified by:

adapt in interface AdapterFactory

Overrides:

adapt in class AdapterFactoryImpl

Parameters:

target - the notifier to adapt.

type - the key indicating the type of adapter required.

Returns:

a previously existing associated adapter, a new associated adapter if possible, or null otherwise.

See Also:

Adapter.setTarget(org.eclipse.emf.common.notify.Notifier), AdapterFactory.adaptNew(org.eclipse.emf.common.notify.Notifier, java.lang.Object)

createAdapter

protected Adapter createAdapter(Notifier target,
                                java.lang.Object type)

Calls createAdapter(Notifier) to create an adapter for the given Notifier and sets its adapter factory to this.

Overrides:

createAdapter in class AdapterFactoryImpl

Parameters:

target - the notifier to adapt.

type - the key indicating the type of adapter required.

Returns:

a new adapter.

See Also:

AdapterFactoryImpl.createAdapter(Notifier)

createAdapter

protected abstract Adapter createAdapter(Notifier target)

Override this to create the adapter for a Notifier. The adapter must implement GeneratorAdapter.

Overrides:

createAdapter in class AdapterFactoryImpl

Parameters:

target - the notifier to adapt.

Returns:

a new adapter.

See Also:

AdapterFactoryImpl.createAdapter(Notifier)

resolve

protected java.lang.Object resolve(java.lang.Object object,
                                   java.lang.Object type)

There's no general way to check if a non-Notifier already has an adapter associated with it, but in cases where there is a way, override this method and do it here. This method parallels adapt(Notifier, Object) for plain Java objects, and is not usually needed when dealing only with EObjects.

Overrides:

resolve in class AdapterFactoryImpl

Parameters:

object - arbitrary object to adapt.

type - the key indicating the type of adapter required.

Returns:

the object itself.

See Also:

AdapterFactoryImpl.adapt(Object,Object)

createAdapter

protected java.lang.Object createAdapter(java.lang.Object object,
                                         java.lang.Object type)

Calls createAdapter(Object) to create an adapter for the given object and sets its adapter factory to this. This method parallels createAdapter(Notifier, Object) for plain Java objects, and is not usually needed when dealing only with EObjects.

createAdapter

protected GeneratorAdapter createAdapter(java.lang.Object object)

The given object is returned if it is, itself, a GeneratorAdapter. This can be overridden to create an appropriate adapter for a object. It parallels createAdapter(Notifier) for plain Java objects, and is and is not usually needed when dealing only with EObjects.

getGenerator

public Generator getGenerator()

Description copied from interface: GeneratorAdapterFactory

Returns the Generator associated with this adapter factory.

Specified by:

getGenerator in interface GeneratorAdapterFactory

See Also:

GeneratorAdapterFactory.setGenerator(Generator)

setGenerator

public void setGenerator(Generator generator)

Description copied from interface: GeneratorAdapterFactory

Sets the Generator associated with this adapter factory.

Specified by:

setGenerator in interface GeneratorAdapterFactory

See Also:

GeneratorAdapterFactory.getGenerator()

initialize

public void initialize(java.lang.Object input)

Performs initialization for the given model-level input object. This implementation does nothing; it should be overridden when options should be set on the generator, or other initialization is required.

Specified by:

initialize in interface GeneratorAdapterFactory

dispose

public abstract void dispose()

Description copied from interface: GeneratorAdapterFactory

Disposes this adapter factory and all of the adapters it has created.

Specified by:

dispose in interface GeneratorAdapterFactory
