Currently it defines generic interfaces, provides simple main memory and disk based storage managers and a robust implementation of an R*-tree, an MVR-tree and a TPR-tree. Supported Features: * Generic main memory and disk based storage managers. * R*-tree index (also supports linear and quadratic splitting). * MVR-tree index (a.k.a. PPR-tree). * TPR-tree index. * Advanced query capabilities, using Strategy and Visitor patterns. * Arbitrary shaped range queries, by defining generic geometry interfaces. * Large parameterization capabilities, including dimensionality, fill factor, node capacity, etc. * STR packing / bulk loading.
