# Class AnnotationClosureVisitor

java.lang.Object
org.codehaus.groovy.ast.CodeVisitorSupport
org.codehaus.groovy.ast.ClassCodeVisitorSupport
org.apache.groovy.contracts.ast.visitor.BaseVisitor
org.apache.groovy.contracts.ast.visitor.AnnotationClosureVisitor

All Implemented Interfaces:
  `ASTNodeMetaData`, `GroovyClassVisitor`, `GroovyCodeVisitor`, `ErrorCollecting`

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.

See Also:
  - `Requires`
  - `Ensures`
  - `BaseVisitor`
