Message in Chinese (Traditional) (中文（繁體）)
從 '<var>X</var>' 呼叫時，重寫型別 '<var>Type Name</var>' 的節點必須傳回相同型別的非 null 值。或者，請覆寫 '<var>Y</var>' 並將它變更為不要造訪此型別的子系。
Unlocalized message
When called from '<var>X</var>', rewriting a node of type '<var>Type Name</var>' must return a non-null value of the same type. Alternatively, override '<var>Y</var>' and change it to not visit children of this type.
