Constructor Detail

GraphEdge

public GraphEdge()

Initializes an edge of a directed graph corresponding to the given DOM Element.

Method Detail

getSourcePoint

public java.awt.Point getSourcePoint()

Returns the point from which to begin drawing the edge. Default is the center of the source element, or null if the source does not exist.

getDestPoint

public java.awt.Point getDestPoint()

Returns the point from which to end drawing the edge. Default is the center of the destination element, or null if the destination does not exist.

getPreferredBounds

public java.awt.Rectangle getPreferredBounds()

Returns the preferred bounds of the graph element. Default is the bounds of the drawn path.

Specified by:

getPreferredBounds in class GraphElement

contains

public boolean contains(int x,
                        int y)

Returns true if the given point is within 3 units of the path from source to destination.

Overrides:

contains in class javax.swing.JComponent

paintComponent

public void paintComponent(java.awt.Graphics g)

Overrides:

paintComponent in class javax.swing.JComponent

updatePath

public void updatePath()

Updates the path used to draw the element. By default, this is a straight line from source to destination.

getPreferredLayer

public java.lang.Integer getPreferredLayer()

Description copied from class: GraphElement

The preferred layer for plotting the receiver - one of the GraphView constants EDGE_LAYER (bottom), IO_LAYER or NODE_LAYER (top).

Specified by:

getPreferredLayer in class GraphElement

setElement

public void setElement(org.w3c.dom.Element el)

Description copied from class: GraphElement

Sets the DOM Element represented by this component and updates its contents.

Overrides:

setElement in class GraphElement

getBounds

public static final java.awt.Rectangle getBounds(java.awt.Component c)

Computes the bounds in graph space of the given Component, which may be contained in a hierarchy of GraphNodes.

Returns:

The computed bounds, or null if the given Component is null.
