    • hasAnnotation

      public static boolean hasAnnotation(org.codehaus.groovy.ast.ASTNode node, Class<?> annotationType)
      Tells whether the given node has an annotation of the given type.
      Parameters:
      node - an AST node
      annotationType - an annotation type
      Returns:
      true iff the given node has an annotation of the given type

    • getAnnotation

      public static org.codehaus.groovy.ast.AnnotationNode getAnnotation(org.codehaus.groovy.ast.ASTNode node, Class<?> annotationType)

    • getStatements

      public static List<org.codehaus.groovy.ast.stmt.Statement> getStatements(org.codehaus.groovy.ast.MethodNode method)
      Returns a list of statements of the given method. Modifications to the returned list will affect the method's statements.
      Parameters:
      method - a method (node)
      Returns:
      a list of statements of the given method

    • hasPlausibleSourcePosition

      public static boolean hasPlausibleSourcePosition(org.codehaus.groovy.ast.ASTNode node)
      Tells if the source position for the given AST node is plausible. Does not imply that the source position is correct.
      Parameters:
      node - an AST node
      Returns:
      true iff the AST node has a plausible source position
