Interface CompositeProjectionInnerStep

public interface CompositeProjectionInnerStep
A step in a "multi-step" composite projection definition where one can define inner projections to get values from.

  • Method Details

    • as

      <V> CompositeProjectionValueStep<?,V> as(Class<V> objectClass)
      Defines the result of the composite projection as the result of applying the given function to the single inner projection defined so far.
      Type Parameters:
      V - The type of objects returned by the projection.
      Parameters:
      objectClass - The type of objects returned by the projection. The class is expected to be mapped (generally through annotations) in such a way that it defines the inner projections.
      Returns:
      The next DSL step.

    • from

      <V1> CompositeProjectionFrom1AsStep<V1> from(SearchProjection<V1> projection)
      Defines one inner projection to get values from, based on a previously-built SearchProjection.
      Type Parameters:
      V1 - The type of values returned by the inner projection.
      Parameters:
      projection - The inner projection.
      Returns:
      The next DSL step.

    • from

      default <V1> CompositeProjectionFrom1AsStep<V1> from(ProjectionFinalStep<V1> dslFinalStep)
      Defines one inner projection to get values from, based on an almost-built SearchProjection.
      Type Parameters:
      V1 - The type of values returned by the inner projection.
      Parameters:
      dslFinalStep - A final step in the projection DSL allowing the retrieval of the inner projection.
      Returns:
      The next DSL step.

    • from

      <V1, V2> CompositeProjectionFrom2AsStep<V1,V2> from(SearchProjection<V1> projection1, SearchProjection<V2> projection2)
      Defines two inner projections to get values from, based on previously-built SearchProjections.
      Type Parameters:
      V1 - The type of values returned by the first inner projection.
      V2 - The type of values returned by the second inner projection.
      Parameters:
      projection1 - The first inner projection.
      projection2 - The second inner projection.
      Returns:
      The next DSL step.

    • from

      Defines two inner projections to get values from, based on almost-built SearchProjections.
      Type Parameters:
      V1 - The type of values returned by the first inner projection.
      V2 - The type of values returned by the second inner projection.
      Parameters:
      dslFinalStep1 - A final step in the projection DSL allowing the retrieval of the first inner projection.
      dslFinalStep2 - A final step in the projection DSL allowing the retrieval of the second inner projection.
      Returns:
      The next DSL step.
