|
* A factory for creating {@link PreparedGeometry}s.
|
||
|
|
*
|
||
|
|
* It chooses an appropriate implementation of PreparedGeometry
|

|
|
* based on the geoemtric type of the input geometry.
|
||
|
|
* In the future, the factory may accept hints that indicate
|
||
|
|
* special optimizations which can be performed.
