Class AbstractActivityGraphsHelperDecorator

java.lang.Object
  org.argouml.model.AbstractActivityGraphsHelperDecorator

All Implemented Interfaces:

ActivityGraphsHelper

Direct Known Subclasses:

UndoActivityGraphsHelperDecorator

public abstract class AbstractActivityGraphsHelperDecorator

extends Object

implements ActivityGraphsHelper

The abstract Decorator for the ActivityGraphsHelper.

getComponent

protected ActivityGraphsHelper getComponent()

The component we are decorating.

Returns:

Returns the component.

findClassifierByName

public Object findClassifierByName(Object ofs,
                                   String s)

Description copied from interface: ActivityGraphsHelper

Finds the Classifier to which a given ObjectFlowState refers by its given name. This function may be used for when the user types the name of a classifier in the diagram, in an ObjectFlowState.

Specified by:

findClassifierByName in interface ActivityGraphsHelper

Parameters:

ofs - the given ObjectFlowState

s - the given String that represents the name of the "type" Classifier

Returns:

the found classifier or null

findStateByName

public Object findStateByName(Object c,
                              String s)

Description copied from interface: ActivityGraphsHelper

Find a state of a Classifier by its name. This routine is used to make the connection between a ClassifierInState and its State.

Specified by:

findStateByName in interface ActivityGraphsHelper

Parameters:

c - the Classifier. If this is not a Classifier, then IllegalArgumentException is thrown.

s - the string that represents the name of the state we are looking for. If "" or null, then null is returned straight away.

Returns:

the State (as Object) or null, if not found.

isAddingActivityGraphAllowed

public boolean isAddingActivityGraphAllowed(Object context)

Description copied from interface: ActivityGraphsHelper

Returns true if an activitygraph may be added to the given context. To decouple ArgoUML as much as possible from the model implementation, the parameter of the method is of type Object.

An ActivityGraph specifies the dynamics of

1. a Package, or
2. a Classifier (including UseCase), or
3. a BehavioralFeature.

Specified by:

isAddingActivityGraphAllowed in interface ActivityGraphsHelper

Parameters:

context - the given context

Returns:

boolean true if an activitygraph may be added

addInState

public void addInState(Object classifierInState,
                       Object state)

Specified by:

addInState in interface ActivityGraphsHelper

Parameters:

classifierInState - the classifierInState

state - the state that will be linked

setInStates

public void setInStates(Object classifierInState,
                        Collection newStates)

Description copied from interface: ActivityGraphsHelper

Replace the complete collection of states by the given new one. This function only modifies the model for added or removed states.

Specified by:

setInStates in interface ActivityGraphsHelper

Parameters:

classifierInState - the ClassifierInState to be altered

newStates - the collection of states
