Package org.codehaus.groovy.ast

## Class Parameter

- java.lang.Object
- - org.codehaus.groovy.ast.ASTNode
  - - org.codehaus.groovy.ast.AnnotatedNode
    - - org.codehaus.groovy.ast.Parameter

- All Implemented Interfaces:
    `GroovydocHolder<AnnotatedNode>`, `NodeMetaDataHandler`, `Variable`

      public class Parameter
      extends AnnotatedNode
      implements Variable

  Represents a parameter on a constructor or method call. The type name is optional - it defaults to java.lang.Object if unknown.
