Constructor Summary

AddCardinalityCommand(FeatureDiagramModel diagram, FeatureNodeModel node, java.lang.String childNodeType, int nodePosition, java.lang.String propertySet)
Creates command that adds new cardinality element to the feature model s

Method Summary

void	execute() calls addCardinality() method of the FeatureDiagramModel that adds the new element to DOM model and consequently updates the canvas
void	redo() calls returnCardinality() method of the FeatureDiagramModel that adds the element to DOM model at the right position and consequently updates the canvas
void	undo() calls unAddCardinality() method of the FeatureDiagramModel that saves the current position of the node in its parent's list of nodes (in the DOM model), removes the node from this list and consequently updates the canvas

Constructor Detail

AddCardinalityCommand

public AddCardinalityCommand(FeatureDiagramModel diagram,
                             FeatureNodeModel node,
                             java.lang.String childNodeType,
                             int nodePosition,
                             java.lang.String propertySet)

Creates command that adds new cardinality element to the feature model s

Parameters:

diagram - the feature model

node - the parent node

childNodeType - the type o node that is to be added

nodePosition - position where the new element is to be inserted (among other siblings) ToDo: rename node to parent, remove property set

Method Detail

execute

public void execute()

calls addCardinality() method of the FeatureDiagramModel that adds the new element to DOM model and consequently updates the canvas

Overrides:

execute in class AddCommand

redo

public void redo()

calls returnCardinality() method of the FeatureDiagramModel that adds the element to DOM model at the right position and consequently updates the canvas

Overrides:

redo in class AddCommand

See Also:

org.eclipse.gef.commands.Command#redo()

undo

public void undo()

calls unAddCardinality() method of the FeatureDiagramModel that saves the current position of the node in its parent's list of nodes (in the DOM model), removes the node from this list and consequently updates the canvas

Overrides:

undo in class AddCommand
