  org.eclipse.emf.ecore.util.Switch<T>
      org.eclipse.emf.ecore.change.util.ChangeSwitch<T>

public class ChangeSwitch<T>
extends Switch<T>

The Switch for the model's inheritance hierarchy. It supports the call doSwitch(object) to invoke the caseXXX method for each class of the model, starting with the actual class of the object and proceeding up the inheritance hierarchy until a non-null result is returned, which is the result of the switch.

Constructor Detail

ChangeSwitch

public ChangeSwitch()

Creates an instance of the switch.

Method Detail

isSwitchFor

protected boolean isSwitchFor(EPackage ePackage)

Checks whether this is a switch for the given package.

Specified by:

isSwitchFor in class Switch<T>

Parameters:

ePackage - the package of interest.

Returns:

whether this is a switch for the given package.

doSwitch

protected T doSwitch(int classifierID,
                     EObject theEObject)

Calls caseXXX for each class of the model until one returns a non null result; it yields that result.

Overrides:

doSwitch in class Switch<T>

Parameters:

classifierID - the classifier ID of the (super-)class of eObject relative to its defining EPackage.

theEObject - the model object to pass to the appropriate caseXXX method.

Returns:

the first non-null result returned by a caseXXX call.

caseChangeDescription

public T caseChangeDescription(ChangeDescription object)

Returns the result of interpreting the object as an instance of 'Description'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Description'.

See Also:

doSwitch(EObject)

caseEObjectToChangesMapEntry

public T caseEObjectToChangesMapEntry(java.util.Map.Entry<EObject,EList<FeatureChange>> object)

Returns the result of interpreting the object as an instance of 'EObject To Changes Map Entry'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'EObject To Changes Map Entry'.

See Also:

doSwitch(EObject)

caseFeatureChange

public T caseFeatureChange(FeatureChange object)

Returns the result of interpreting the object as an instance of 'Feature Change'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Feature Change'.

See Also:

doSwitch(EObject)

caseListChange

public T caseListChange(ListChange object)

Returns the result of interpreting the object as an instance of 'List Change'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'List Change'.

See Also:

doSwitch(EObject)

caseResourceChange

public T caseResourceChange(ResourceChange object)

Returns the result of interpreting the object as an instance of 'Resource Change'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Resource Change'.

See Also:

doSwitch(EObject)

caseFeatureMapEntry

public T caseFeatureMapEntry(FeatureMapEntry object)

Returns the result of interpreting the object as an instance of 'Feature Map Entry'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'Feature Map Entry'.

See Also:

doSwitch(EObject)

defaultCase

public T defaultCase(EObject object)

Returns the result of interpreting the object as an instance of 'EObject'. This implementation returns null; returning a non-null result will terminate the switch, but this is the last case anyway.

Overrides:

defaultCase in class Switch<T>

Parameters:

object - the target of the switch.

Returns:

the result of interpreting the object as an instance of 'EObject'.
