Interface EntityProjectionIntrospector.ProjectionPredicate

Enclosing class:
EntityProjectionIntrospector

public static interface EntityProjectionIntrospector.ProjectionPredicate
Represents a predicate (boolean-valued function) of a target type and its underlying type.
  • Method Details

    • test

      boolean test(Class<?> target, Class<?> underlyingType)
      Evaluates this predicate on the given arguments.
      Parameters:
      target - the target type.
      underlyingType - the underlying type.
      Returns:
      true if the input argument matches the predicate, otherwise false.
    • and

      Return a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

      Parameters:
      other - a predicate that will be logically-ANDed with this predicate
      Returns:
      a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate
    • negate

      Return a predicate that represents the logical negation of this predicate.
      Returns:
      a predicate that represents the logical negation of this predicate
    • typeHierarchy

      Return a predicate that considers whether the target type is participating in the type hierarchy.
