    Methods
    Type Params | Return Type | Name and description
    --- | --- | ---
    `` | `ClassNode` | `getType()`
    `` | `void` | `setType(ClassNode t)`
    `` | `Expression` | `transformExpression(ExpressionTransformer transformer)` Return a copy of the expression calling the transformer on any nested expressions
