Class EdgeProxy

java.lang.Object
  i3.dragos.gm.core.proxy.GraphEntityProxy
      i3.dragos.gm.core.proxy.EdgeProxy

All Implemented Interfaces:

Edge, GraphEntity, ExistenceCheckable, MetaAttributable

public class EdgeProxy
extends GraphEntityProxy
implements Edge

An EdgeProxy delegates all method calls to the underlying edge except for those that access fields which are used after an edge has been deleted.

Constructor Detail

EdgeProxy

public EdgeProxy(Edge e)

Constructs a new wrapper for an edge.

Parameters:

e - The edge to wrap.

Method Detail

getEdgeClass

public EdgeClass getEdgeClass()
                       throws DragosException

Returns the type of the edge.

Actually, this method is just a correctly typed wrapper for calling GraphEntity.getGraphEntityClass().

Specified by:

getEdgeClass in interface Edge

Returns:

the edge class of the edge.

Throws:

DragosException - if something went wrong.

setSource

public void setSource(GraphEntity g)
               throws EntityNotFoundException,
                      DragosException

Sets the source graph element.

Specified by:

setSource in interface Edge

Parameters:

g - the source graph element (may be null).

Throws:

EntityNotFoundException - if the source was not null and could not be found.

DragosException - if something went wrong.

getSource

public GraphEntity getSource()
                      throws DragosException

Returns the source graph element.

Specified by:

getSource in interface Edge

Returns:

the source graph element.

Throws:

DragosException - if something went wrong.

setTarget

public void setTarget(GraphEntity g)
               throws EntityNotFoundException,
                      DragosException

Sets the target graph element.

Specified by:

setTarget in interface Edge

Parameters:

g - the target graph element (may be null).

Throws:

EntityNotFoundException - if the target was not null and could not be found.

DragosException - if something went wrong.

getTarget

public GraphEntity getTarget()
                      throws DragosException

Returns the target graph element.

Specified by:

getTarget in interface Edge

Returns:

the target graph element.

Throws:

DragosException - if something went wrong.

isDirected

public boolean isDirected()
                   throws DragosException

Returns true if the edge is directed and false otherwise.

Specified by:

isDirected in interface Edge

Returns:

true if the edge is directed and false otherwise.

Throws:

DragosException - if something went wrong.
