de.grogra.imp3d.objects

Class PolygonsBase

java.lang.Object

de.grogra.imp3d.objects.PolygonsBase

All Implemented Interfaces:

ContextDependent, Polygons, Polygonization, java.io.Serializable

Direct Known Subclasses:

PolygonMesh

public abstract class PolygonsBase
extends java.lang.Object
implements Polygons, java.io.Serializable

This abstract class can be used as superclass for user-defined polygonal data. The method Polygonization.polygonize(de.grogra.graph.ContextDependent, de.grogra.graph.GraphState, de.grogra.imp3d.PolygonArray, int, float) has to be implemented.

Method Detail

dependsOnContext

public boolean dependsOnContext()

Description copied from interface: ContextDependent

Determines whether this object actually depends on context.

Specified by:

dependsOnContext in interface ContextDependent

Returns:

true iff this object depends on context

getStamp

public int getStamp()

writeStamp

public void writeStamp(Cache.Entry cache,
              GraphState gs)

Description copied from interface: ContextDependent

Writes a stamp of the context into cache. Based on this stamp, a cache detects whether the context of this object has changed or not.

Specified by:

writeStamp in interface ContextDependent

Parameters:

cache - a cache entry to write the stamp

gs - the current graph state
