public interface LineSegmentizable

If a LineSegmentizable object is the value of the attribute Attributes.SHAPE, it defines a shape which is composed of line segments.

Method Summary

ContextDependent	getSegmentizableSource(GraphState gs) Defines the data source on which the line segmentization depends.
int	getStamp()
void	segmentize(ContextDependent source, GraphState gs, LineArray out, float flatness) Performs the segmentization of the source into line segments.

Method Detail

getSegmentizableSource

ContextDependent getSegmentizableSource(GraphState gs)

Defines the data source on which the line segmentization depends.

Parameters:

gs - the current graph state

Returns:

the data source

getStamp

int getStamp()

segmentize

void segmentize(ContextDependent source,
                GraphState gs,
                LineArray out,
                float flatness)

Performs the segmentization of the source into line segments. The field out.userObject is not modified.

Parameters:

source - the data source as reported by a previous invocation of getSegmentizableSource(GraphState) with the same gs

gs - the current graph state

out - the line segments are written to out

flatness - a parameter for the degree of flatness, a typical value is 1
