Interface EquivalenceStrategy

All Known Implementing Classes:

ParameterizedEquivalenceStrategy

public interface EquivalenceStrategy

A strategy used to determine equivalence of prism items and values. This is quite generic interface. We expect that usually it will not be implemented directly, because comparing prism structures is a complex undertaking. The usual approach will be using ParameterizedEquivalenceStrategy that contains a set of parameters that drive equals/hashCode methods built into prism structures. However, if anyone would need the ultimate flexibility, he is free to implement this interface from scratch. (Note that not all methods in prism API accept this generic form of equivalence strategy. For example, diff(..) methods are limited to ParameterizedEquivalenceStrategy at least for now.)
