public interface PreparedGeometry
An interface for classes which prepare Geometry
s
in order to optimize the performance
of repeated calls to specific geometric operations.
A given implementation may provide optimized implementations
for only some of the specified methods,
and delegate the remaining methods to the original Geometry
operations.
An implementation may also only optimize certain situations,
and delegate others.
See the implementing classes for documentation about which methods and situations
they optimize.
Method Summary  

boolean 
contains(Geometry geom)

Method Detail 

Geometry getGeometry()
Geometry
which has been prepared.
boolean contains(Geometry geom)
Geometry
contains a given geometry.
geom
 the Geometry to test
Geometry.contains(Geometry)
boolean containsProperly(Geometry geom)
Geometry
properly contains a given geometry.
The containsProperly
predicate has the following equivalent definitions:
[T**FF*FF*]
Geometry.contains(com.vividsolutions.jts.geom.Geometry)
predicate,
in which test geometries can intersect the target's boundary and still be contained.
The advantage of using this predicate is that it can be computed efficiently, since it avoids the need to compute the full topological relationship of the input boundaries in cases where they intersect.
An example use case is computing the intersections of a set of geometries with a large polygonal geometry. Since intersection is a fairly slow operation, it can be more efficient to use containsProperly to filter out test geometries which lie wholly inside the area. In these cases the intersection is known a priori to be exactly the original test geometry.
