Detailed Description

SymmetryElementFactoryImpl does not generate SymmetryElement objects directly.

Instead, in order to stay as flexible as possible, it stores instances of AbstractSymmetryElementGenerator. Each subclass of AbstractSymmetryElementGenerator can be registered once into the factory, which then uses the canProcess-method to determine whether a certain generator can be used to derive the SymmetryElement that corresponds to the SymmetryOperation.

More about how the symmetry elements are derived from matrix/vector pairs can be found in the International Tables for Crystallography A, section 11.2.
