## Class ExtendedVerifier

- java.lang.Object
- - org.codehaus.groovy.ast.CodeVisitorSupport
  - - org.codehaus.groovy.ast.ClassCodeVisitorSupport
    - - org.codehaus.groovy.classgen.ExtendedVerifier

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

      public class ExtendedVerifier
      extends ClassCodeVisitorSupport

  A specialized Groovy AST visitor meant to perform additional verifications upon the current AST. Currently it does checks on annotated nodes and annotations itself.

  Current limitations: - annotations on local variables are not supported
