Method Detail

drawProtected

protected void drawProtected(java.awt.Graphics g,
                             int scale,
                             int mode,
                             int value)

Zeichnet den Linienzug im Graphic Context g, vorausgesetzt der aktuelle Maßstab wird eingehalten.

Overrides:

drawProtected in class DrawablePolygon

Parameters:

g - aktueller Graphic Context

scale - aktueller Maßstab

mode - aktueller Darstellungsmodus

value - Darstellungswert

interacts

public boolean interacts(int x,
                         int y,
                         int scale)

Description copied from class: Drawable

Tests whether the primitive is selected by a given point or not. The default implementation is based on the mbr of the primitive.

Overrides:

interacts in class Drawable

Parameters:

x - x-coordinate of the point

y - y-coordinate of the point

scale - actuals scale

Returns:

selected?

writeGML

public void writeGML(EntryWriter out)

Writes the primitive as GML tag.

Overrides:

writeGML in class DrawablePolygon

Parameters:

out - entry writer
