Interface ValueStore

All Known Implementing Classes:

XMLValidator.ValueStoreBase

public interface ValueStore

Interface for storing values associated to an identity constraint. Each value stored corresponds to a field declared for the identity constraint. One instance of an object implementing this interface is created for each identity constraint per element declaration in the instance document to store the information for this identity constraint.

Note: The component performing identity constraint collection and validation is responsible for providing an implementation of this interface. The component is also responsible for performing the necessary checks required by each type of identity constraint.
