Method Detail

• handle

  public void handle(AnnotationValues<NonNull> annotation,
            com.sun.tools.javac.tree.JCTree.JCAnnotation ast,
            JavacNode annotationNode)

  Description copied from class: JavacAnnotationHandler
  Called when an annotation is found that is likely to match the annotation you're interested in. Be aware that you'll be called for ANY annotation node in the source that looks like a match. There is, for example, no guarantee that the annotation node belongs to a method, even if you set your TargetType in the annotation to methods only.

  Specified by:

  handle in class JavacAnnotationHandler<NonNull>

  Parameters:

  annotation - The actual annotation - use this object to retrieve the annotation parameters.

  ast - The javac AST node representing the annotation.

  annotationNode - The Lombok AST wrapper around the 'ast' parameter. You can use this object to travel back up the chain (something javac AST can't do) to the parent of the annotation, as well as access useful methods such as generating warnings or errors focused on the annotation.

• isNullCheck

  public boolean isNullCheck(com.sun.tools.javac.tree.JCTree.JCStatement stat)

• returnVarNameIfNullCheck

  public String returnVarNameIfNullCheck(com.sun.tools.javac.tree.JCTree.JCStatement stat)

  Checks if the statement is of the form 'if (x == null) {throw WHATEVER;}, where the block braces are optional. If it is of this form, returns "x". If it is not of this form, returns null.
