public class GraphEdge

Object
GraphEdge

A connection from one node to another, optionally from a port to a port.

Constructors

`public GraphEdge(String id, String sourceId, String targetId)`	An edge between two nodes.
`public GraphEdge(String id, String sourceId, String sourcePortId, String targetId, String targetPortId)`	An edge between two ports.

Methods

`public` `String getId()`	The id, unique within the model.
`public` `String getSourceId()`	The id of the node the edge leaves.
`public` `String getSourcePortId()`	The id of the output port the edge leaves, or null.
`public` `String getTargetId()`	The id of the node the edge enters.
`public` `String getTargetPortId()`	The id of the input port the edge enters, or null.
`public` `String getLabel()`	The text painted at the middle of the edge, or null.
`public void setLabel(String label)`	Sets the label.
`public boolean isDirected()`	True, the default, when the edge is painted with an arrowhead.
`public void setDirected(boolean directed)`	Paints the edge with or without an arrowhead.
`public` `String getStyleKey()`	A key a renderer may map to a colour or a dash, or null.
`public void setStyleKey(String styleKey)`	Sets the style key.
`public` `Object getUserData()`	Anything the application keeps with the edge.
`public void setUserData(Object userData)`	Sets the application’s data.
`public double[] getRoute()`	The bend points an arrangement routed the edge through, as x, y pairs in world units, or null for a direct line between its ends.
`public void setRoute(double[] route)`	Sets the bend points; null removes them.
`public boolean touches(String nodeId)`	True when the edge touches the node with this id.
