Package org.eclipse.graphiti.services.impl

Class GaServiceImpl

java.lang.Object
org.eclipse.graphiti.services.impl.GaServiceImpl
All Implemented Interfaces:
IGaCreateService, IGaLayoutService, IGaService
public class GaServiceImpl extends Object implements IGaService
Provides the default implementation for the Graphiti GraphicsAlgorithm related services. Usually clients consume this service via Graphiti.getGaService() or Graphiti.getGaCreateService() and get the default behavior, but Clients can subclass this to modify the default attributes that will be set for Text or MultiText graphics algorithms like the default font by overriding #setDefaultTextAttributes(Diagram, AbstractText, String, boolean). Also default attributes of other graphics algorithms can be influenced by overriding setDefaultGraphicsAlgorithmAttributes(GraphicsAlgorithm). Note that in this case Graphiti does not provide any means to manage the service class instance and to access it from any place.
