43 | | * A factory for creating {@link PreparedGeometry}s. |
44 | | * |
45 | | * It chooses an appropriate implementation of PreparedGeometry |
46 | | * based on the geoemtric type of the input geometry. |
47 | | * In the future, the factory may accept hints that indicate |
48 | | * special optimizations which can be performed. |
