public class cgraph_sem_draw

extends nametag_sem_draw

implements interactor_pred, interactor_consts

An interface_pred predicate class that performs a semantic redraw action for a semantic lens. In this case the object draws debugging information about the constraint dependency graph of each object (along with a class name tag and bounding box). This predicate expects a sem_draw_context object as its parameters argument. This predicate is executed for its side effect only and always returns false.

Constructor Detail

cgraph_sem_draw

public cgraph_sem_draw(java.awt.Font fnt,
                       java.awt.Color c)

Full constructor.

Parameters:

Font - fnt the font to draw tags in.

Color - c the color to draw tags and borders in.

cgraph_sem_draw

public cgraph_sem_draw()

Constructor using default font and tag color.

Method Detail

test

public boolean test(interactor obj,
                    java.lang.Object parameters)

Perform the predicate test.

Specified by:

test in interface interactor_pred

Parameters:

obj - the interactor the predicate is drawing.

parameters - a sem_draw_context object containing the a drawable object and other bookkeeping needed for drawing.

Returns:

false in all cases.

Overrides:

test in class nametag_sem_draw

draw_constraint

protected void draw_constraint(drawable surf,
                               interactor obj,
                               int enc,
                               int orient,
                               int xpos,
                               int ypos)

Draw the dependency lines for a given encoded constraint (which is attached to the given object and uses the given orientation). The lines start at locations indicated by the dependencies of the encoded constraint, and end at the given position.

Parameters:

drawable - surf where the drawing takes place

interactor - obj object the constraint is attached to (hence where * dependencies are relative to).

int - enc encoding of the constraint.

int - orient orientation of the constraint.

int - xpos x position of edge end points

int - ypos y position of edge end points
