Modifying Functions


The modify-argument node specifies which of the given function’s arguments the modification affects, and is a child of the modify-function node. Use the remove-argument, replace-default-expression, remove-default-expression, replace-type, reference-count and define-ownership nodes to specify the details of the modification.

    <modify-argument index="return | this | 1 ..." rename="...">
        // modifications

Set the index attribute to “1” for the first argument, “2” for the second one and so on. Alternatively, set it to “return” or “this” if you want to modify the function’s return value or the object the function is called upon, respectively.

The optional rename attribute is used to rename a argument and use this new name in the generated code.
