emitter.setMaxListeners(n)
n
<integer>- 返回: <EventEmitter>
默认情况下,如果为特定事件添加了 10
个以上的监听器,则 EventEmitter
将打印警告。
这是一个有用的默认值,有助于查找内存泄漏。
emitter.setMaxListeners()
方法允许修改此特定 EventEmitter
实例的限制。
该值可以设置为 Infinity
(或 0
)以指示无限数量的监听器。
返回对 EventEmitter
的引用,以便可以链式调用。
n
<integer>- Returns: <EventEmitter>
By default EventEmitter
s 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. The emitter.setMaxListeners()
method allows the limit to be
modified for this specific EventEmitter
instance. The value can be set to
Infinity
(or 0
) to indicate an unlimited number of listeners.
Returns a reference to the EventEmitter
, so that calls can be chained.
