addTrailers(headers: Any): Unit
This method adds HTTP trailing headers (a header but at the end of the message) to the response.
This method adds HTTP trailing headers (a header but at the end of the message) to the response. Trailers will only be emitted if chunked encoding is used for the response; if it is not (e.g., if the request was HTTP/1.0), they will be silently discarded.
Note that HTTP requires the Trailer header to be sent if you intend to emit trailers, with a list of the header fields in its value.

def
on(eventName: String, listener: Function): ServerResponse.this.type
Adds the listener function to the end of the listeners array for the event named eventName.
Adds the listener function to the end of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.
Returns a reference to the EventEmitter so calls can be chained.
- Definition Classes

Example: -
def
once(eventName: String, listener: Function): ServerResponse.this.type
Adds a one time listener function for the event named eventName.
Adds a one time listener function for the event named eventName. This listener is invoked only the next time eventName is triggered, after which it is removed.

def
removeAllListeners(): ServerResponse.this.type
Removes all listeners, or those of the specified eventName.
Removes all listeners, or those of the specified eventName.
Note that it is bad practice to remove listeners added elsewhere in the code, particularly when the EventEmitter instance was created by some other component or module (e.g. sockets or file streams).
Returns a reference to the EventEmitter so calls can be chained.

def
removeAllListeners(eventName: String): ServerResponse.this.type

Removes all listeners, or those of the specified eventName.

removeHeader(name: String): Unit

-
def
removeListener(eventName: String, listener: Function): ServerResponse.this.type
Removes the specified listener from the listener array for the event named eventName.
Removes the specified listener from the listener array for the event named eventName. removeListener will remove, at most, one instance of a listener from the listener array. If any single listener has been added multiple times to the listener array for the specified eventName, then removeListener must be called multiple times to remove each instance.
Note that once an event has been emitted, all listeners attached to it at the time of emitting will be called in order. This implies that any removeListener() or removeAllListeners() calls after emitting and before the last listener finishes execution will not remove them from emit() in progress. Subsequent events will behave as expected.

val
sendDate: Boolean
When true, the Date header will be automatically generated and sent in the response if it is not already present in the headers.

def
setHeader(name: String, value: String): Unit
Sets a single header value for implicit headers.
Sets a single header value for implicit headers. If this header already exists in the to-be-sent headers, its value will be replaced. Use an array of strings here if you need to send multiple headers with the same name.
-
def
setMaxListeners(n: Int): ServerResponse.this.type
By default EventEmitters will print a warning if more than 10 listeners are added for a particular event.
By default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default that helps finding memory leaks. Obviously, not all events should be limited to just 10 listeners. The emitter.setMaxListeners() method allows the limit to be modified for this specific EventEmitter instance. The value can be set to Infinity (or 0) for to indicate an unlimited number of listeners.
Returns a reference to the EventEmitter so calls can be chained.
- Definition Classes
- IEventEmitter
emitter.setMaxListeners(n)
Example: -
def
setTimeout(msecs: Int, callback: Function): Unit
Sets the Socket's timeout value to msecs.
Sets the Socket's timeout value to msecs. If a callback is provided, then it is added as a listener on the 'timeout' event on the response object.
If no 'timeout' listener is added to the request, the response, or the server, then sockets are destroyed when they time out. If you assign a handler on the request, the response, or the server's 'timeout' events, then it is your responsibility to handle timed out sockets.
Returns response.
- def status(statusCode: Int): ServerResponse.this.type
-
val
statusCode: Int
When using implicit headers (not calling response.writeHead() explicitly), this property controls the status code that will be sent to the client when the headers get flushed.
-
val
statusMessage: UndefOr[String]
When using implicit headers (not calling response.writeHead() explicitly), this property controls the status message that will be sent to the client when the headers get flushed.
When using implicit headers (not calling response.writeHead() explicitly), this property controls the status message that will be sent to the client when the headers get flushed. If this is left as undefined then the standard message for the status code will be used.
