Interface Specification<T extends Searchable>

Type Parameters:

T - domain object on which search will be performed.

public interface Specification<T extends Searchable>

Search predicate which can be used to filter domain objects from the remote server using searchable repository.

Specification is defined in DSL with keyword specification and a predicate. Server can convert specification to SQL query on the fly or call database function created at compile time. Other optimization techniques can be used too.

DSL example:

 module Todo {
   aggregate Task {
       timestamp createdOn;
       specification findBetween 
           'it => it.createdOn >= after && it.createdOn <= before'  {
         date after;
         date before;
       }
 }
