Node

public Node(Grammar grammar,
            NodeType typ,
            Node sub)

Method Detail

unparse

public void unparse(StringBuffer buf)

setWrapSize

public void setWrapSize(Chart chart)

calcSize

public Size calcSize(Chart chart)

Calculates the size of each symbol.

calcPos

public void calcPos(Chart chart,
                    float posBegin)

Calculates the horizontal position of the symbols.

drawComponents

public void drawComponents(Chart chart,
                           Point2D.Float p,
                           Size s)

Draws the components from left to right.

Each component paints itself and then give its coordinates to its sub-components for a recursive call, or if applicable, a call to the drawComponentsInverse(net.hydromatic.clapham.graph.Chart, java.awt.geom.Point2D.Float, net.hydromatic.clapham.graph.Size) method.

accept

public void accept(net.hydromatic.clapham.graph.Chart.NodeVisitor nodeVisitor)

visitChildren

public void visitChildren(net.hydromatic.clapham.graph.Chart.NodeVisitor visitor)
