Class Edge

java.lang.Object

com.uppaal.model.core2.Element

com.uppaal.model.core2.Node

com.uppaal.model.core2.Edge

All Implemented Interfaces:

Serializable, Cloneable

public class Edge
extends Node

Edge models discrete transitions between locations.

An Edge may have Nails as children in the Node.

Probabilistic edges are modeled by a pair of Edges connected via BranchPoint.

Edges may have labels modeled by properties: "select", "guard", "synchronisation", "assignment", "probability", "controllable", "comments", "color".

Constructor Detail

Edge

public Edge(Element prototype)

Constructs an Edge based on a prototype. Use Template#createEdge() instead and then insert it into Template.

Parameters:

prototype - the element containing default properties.

See Also:

Template.createEdge(), Element.importInto(com.uppaal.model.core2.Element)

Method Detail

getSource

public AbstractLocation getSource()

Returns the source location (the beginning of the edge).

Returns:

abstract location (can be BranchPoint)

getTarget

public AbstractLocation getTarget()

Returns the target location (the end of the edge).

Returns:

abstract location (can be BranchPoint)

getNails

public Nail getNails()

Returns the first nail (if any).

Returns:

nail or null if there are no nails on this edge.

setSource

public void setSource(AbstractLocation source)

Sets the origin of this edge.

Parameters:

source - the origin: Location or BranchPoint

setTarget

public void setTarget(AbstractLocation target)

Sets the destination of this edge.

Parameters:

target - the destination: Location or BranchPoint

createNail

public Nail createNail()

Creates a nail based on prototype, the nail has to be inserted into an edge.

Returns:

a new nail

accept

public void accept(Visitor visitor)
            throws Exception

Description copied from class: Element

Accept a visitor. This method is specialized in every subclass. Part of the visitor pattern.

Overrides:

accept in class Node

Parameters:

visitor - - The visitor

Throws:

Exception - the visitor threw an exception.

getPrototypeFromParent

public Element getPrototypeFromParent(Element parent)

Returns the #edge property value of the parent argument.

Overrides:

getPrototypeFromParent in class Element

Parameters:

parent - - The parent element

Returns:

The property element

getName

public String getName()

Constructs a human-friendly name of this edge. The result contains a source and target location names separated by an arrow.

Returns:

a human-friendly name for this edge
