Simple implementation of an
IHandleProvider
that can be used for
IEdges.
It will return the
IHandles for
the source and target ports using
PortRelocationHandles.
Note that this implementation also explicitly implements the
IEdgePortHandleProvider and
that it is recommended to decorate the
IEdgePortHandleProvider interface with edges
in order to influence the handles of the source and target port of the edge instead of directly decorating and
implementing the
IHandleProvider interface. The default implementation of the
IHandleProvider
interface in the lookup of the
IEdges (see
DefaultEdgeLookup) will use
the
IEdgePortCandidateProvider interface to collect the source and target port handles.
edge:IEdge
The edge this provider is working on.
Implementation protected function get edge():IEdge protected function set edge(value:IEdge):voidgraph:IGraph
The graph this provider is working on.
Implementation protected function get graph():IGraph protected function set graph(value:IGraph):voidpublic function PortRelocationHandleProvider(graph:IGraph, edge:IEdge)
Initializes a new instance of the PortRelocationHandleProvider class
using the given graph and edge.
Parameters | graph:IGraph — The graph or null. If the graph is null, the handles will try to
receive the graph from the GraphCanvasComponent it is used in.
|
| |
| edge:IEdge — The edge.
|
protected function createPortRelocationHandle(graph:IGraph, edge:IEdge, sourcePort:Boolean):IHandle
Factory method that creates the a PortRelocationHandle.
Parameters
| graph:IGraph — The graph that contains the edge.
|
| |
| edge:IEdge — The edge.
|
| |
| sourcePort:Boolean — If set to true, the handle for the source port is sought.
|
Returns public function getHandle(context:IInputModeContext, edge:IEdge, sourceHandle:Boolean):IHandle
Gets an IHandle implementation for one end of the provided edge.
Parameters
| context:IInputModeContext — The context in which the handle will be used.
|
| |
| edge:IEdge — The edge for which an handle is needed.
|
| |
| sourceHandle:Boolean — If set to true the handle for the source side/port should be returned.
|
Returns | IHandle — The handle to use for the provided side or null.
|
public function getHandles(context:IInputModeContext):Collection
Returns a collection of zero or more IHandle implementations
that are associated with this instance.
