Constructor Detail

LineSegmentizationCache

public LineSegmentizationCache(GraphState gs,
                               float flatness)

Constructs a new cache. The parameters will be passed to LineSegmentizable.segmentize(ContextDependent, GraphState, LineArray, float) when a cache entry is to be computed.

Parameters:

gs - the graph state within which the cache will be used

flatness - the flatness to pass to segmentize

Method Detail

createEntry

protected Cache.Entry createEntry(java.lang.Object obj,
                                  boolean node,
                                  ContextDependent dep,
                                  java.lang.Object strategy)

Specified by:

createEntry in class Cache

get

public LineArray get(java.lang.Object object,
                     boolean asNode,
                     LineSegmentizable ls)

Returns the LineArray of a LineSegmentizable in the given object context.

Parameters:

object - the context

asNode - true if object is a node, false if object is an edge

ls - the segmentizable

Returns:

a LineArray, computed by ls
