transform.destroy([error])

• error <Error>
• 返回: <this>

销毁流，并可选择地触发 'error' 事件。 在此调用之后，转换流将释放任何内部资源。 实现者不应覆盖此方法，而应实现 readable._destroy()。 Transform 的 _destroy() 的默认实现也会触发 'close'，除非 emitClose 设置为 false。

一旦 destroy() 被调用，任何进一步的调用都将是空操作，并且除了来自 _destroy() 的其他错误不会作为 'error' 触发。

• error <Error>
• Returns: <this>

Destroy the stream, and optionally emit an 'error' event. After this call, the transform stream would release any internal resources. Implementors should not override this method, but instead implement readable._destroy(). The default implementation of _destroy() for Transform also emit 'close' unless emitClose is set in false.

Once destroy() has been called, any further calls will be a no-op and no further errors except from _destroy() may be emitted as 'error'.
