Interface ActivityGraphsHelper

All Known Implementing Classes:

AbstractActivityGraphsHelperDecorator

public interface ActivityGraphsHelper

The interface for the helper for ActivityGraphs.

Created from the old ActivityGraphsHelper.

findClassifierByName

public Object findClassifierByName(Object ofs,
                                   String s)

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.

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)

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

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)

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.

Parameters:

context - the given context

Returns:

boolean true if an activitygraph may be added

addInState

public void addInState(Object classifierInState,
                       Object state)

Parameters:

classifierInState - the classifierInState

state - the state that will be linked

setInStates

public void setInStates(Object classifierInState,
                        Collection newStates)

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

Parameters:

classifierInState - the ClassifierInState to be altered

newStates - the collection of states
