## [Java] Class AnnotationClosureVisitor

- org.apache.groovy.contracts.ast.visitor.AnnotationClosureVisitor

- All Implemented Interfaces and Traits:
    ASTNodeMetaData

      public class AnnotationClosureVisitor
      extends BaseVisitor
      implements ASTNodeMetaData

  Visits interfaces & classes and looks for `@Requires` or `@Ensures` and creates Closure classes for the annotation closures.

  The annotation closure classes are used later on to check interface contract pre- and post-conditions in implementation classes.

    Ensures
