public interface Resolver<ProductType,CriteriaType>

Generic interface for resolvers which process specified criteria and produce some implementation-specific result information.

Method Summary

Iterable<ProductType>	resolve(CriteriaType criteria) Process the specified criteria and return the resulting instances the the product type which satisfy the criteria.
ProductType	resolveSingle(CriteriaType criteria) Process the specified criteria and return a single instance of the product type which satisfies the criteria.

Method Detail

resolve

Iterable<ProductType> resolve(CriteriaType criteria)
                              throws SecurityException

Process the specified criteria and return the resulting instances the the product type which satisfy the criteria.

Parameters:

criteria - the criteria to evaluate or process

Returns:

instances which satisfy the criteria

Throws:

SecurityException - thrown if there is an error processing the specified criteria

resolveSingle

ProductType resolveSingle(CriteriaType criteria)
                          throws SecurityException

Process the specified criteria and return a single instance of the product type which satisfies the criteria. If multiple items satisfy the criteria, the choice of which single item to return is implementation-dependent.

Parameters:

criteria - the criteria to evaluate or process

Returns:

instances which satisfy the criteria

Throws:

SecurityException - thrown if there is an error processing the specified criteria
