public class ChangeSwitch
extends Object

The Switch for the model's inheritance hierarchy.

Constructor Detail

ChangeSwitch

public ChangeSwitch()
Creates an instance of the switch.

Method Detail

doSwitch

public Object doSwitch(EObject theEObject)
Calls caseXXX for each class of the model until one returns a non null result; it yields that result.

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

doSwitch

protected Object doSwitch(EClass theEClass,
                          EObject theEObject)
Calls caseXXX for each class of the model until one returns a non null result; it yields that result.

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

doSwitch

protected Object doSwitch(int classifierID,
                          EObject theEObject)
Calls caseXXX for each class of the model until one returns a non null result; it yields that result.

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

caseChangeDescription

public Object caseChangeDescription(ChangeDescription object)
Returns the result of interpretting 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 interpretting the object as an instance of 'Description'.
See Also:
doSwitch(EObject)

caseEObjectToChangesMapEntry

public Object caseEObjectToChangesMapEntry(Map.Entry object)
Returns the result of interpretting 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 interpretting the object as an instance of 'EObject To Changes Map Entry'.
See Also:
doSwitch(EObject)

caseFeatureChange

public Object caseFeatureChange(FeatureChange object)
Returns the result of interpretting 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 interpretting the object as an instance of 'Feature Change'.
See Also:
doSwitch(EObject)

caseListChange

public Object caseListChange(ListChange object)
Returns the result of interpretting 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 interpretting the object as an instance of 'List Change'.
See Also:
doSwitch(EObject)

caseResourceChange

public Object caseResourceChange(ResourceChange object)
Returns the result of interpretting 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 interpretting the object as an instance of 'Resource Change'.
See Also:
doSwitch(EObject)

caseFeatureMapEntry

public Object caseFeatureMapEntry(FeatureMapEntry object)
Returns the result of interpretting 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 interpretting the object as an instance of 'Feature Map Entry'.
See Also:
doSwitch(EObject)

defaultCase

public Object defaultCase(EObject object)
Returns the result of interpretting 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.

Parameters:
object - the target of the switch.
Returns:
the result of interpretting the object as an instance of 'EObject'.
