Interface IQueryGroup

All Known Implementing Classes:
BaseGeneratedPatternGroup, BaseQueryGroup, GenericQueryGroup
public interface IQueryGroup
Generic interface for group of query specifications.

It handles more than one patterns as a group, and provides functionality to initialize the matchers together (which has performance benefits).

  • Method Details

    • prepare

      void prepare(InterpreterEngine engine)
      Initializes matchers for the group of patterns within an InterpreterEngine. If some of the pattern matchers are already constructed in the engine, no task is performed for them.

      This preparation step has the advantage that it prepares pattern matchers for an arbitrary number of patterns in a single-pass traversal of the model. This is typically more efficient than traversing the model each time an individual pattern matcher is initialized on demand. The performance benefit only manifests itself if the engine is not in wildcard mode.

      Parameters:
      engine - the existing Refinery Interpreter engine in which the matchers will be created.

    • getSpecifications

      Set<IQuerySpecification<?>> getSpecifications()
      Returns the currently assigned IQuerySpecifications.
