Class Specification

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

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;
    }
  }
}
