Utf8Stream

Whether the stream is appending to the file or truncating it.

The type of data that can be written to the stream. Supported values are 'utf8' or 'buffer'.

The file descriptor that is being written to.

The file that is being written to.

Whether the stream is performing a fs.fsyncSync() after every write operation.

The maximum length of the internal buffer. If a write operation would cause the buffer to exceed maxLength, the data written is dropped and a drop event is emitted with the dropped data.

The minimum length of the internal buffer that is required to be full before flushing.

Whether the stream should ensure that the directory for the dest file exists. If true, it will create the directory if it does not exist.

The mode of the file that is being written to.

The number of milliseconds between flushes. If set to 0, no periodic flushes will be performed.

Whether the stream is writing synchronously or asynchronously.

Whether the stream is currently writing data to the file.

Alias for emitter.on(eventName, listener).

events.EventEmitter

Close the stream immediately, without flushing the internal buffer.

Synchronously calls each of the listeners registered for the event named eventName, in the order they were registered, passing the supplied arguments to each.

Close the stream gracefully, flushing the internal buffer before closing.

Returns an array listing the events for which the emitter has registered listeners. The values in the array are strings or Symbols.

Writes the current buffer to the file if a write was not in progress. Do nothing if minLength is zero or if it is already writing.

Flushes the buffered data synchronously. This is a costly operation.

Returns the current max listener value for the EventEmitter which is either set by emitter.setMaxListeners(n) or defaults to {@link EventEmitter.defaultMaxListeners}.

Returns the number of listeners listening for the event named eventName. If listener is provided, it will return how many times the listener is found in the list of the listeners of the event.

Returns a copy of the array of listeners for the event named eventName.

Alias for emitter.removeListener().

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.

Adds a one-time listener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

Adds the listener function to the beginning 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.

Adds a one-timelistener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

Returns a copy of the array of listeners for the event named eventName, including any wrappers (such as those created by .once()).

Removes all listeners, or those of the specified eventName.

Removes the specified listener from the listener array for the event named eventName.

Reopen the file in place, useful for log rotation.

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. 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.

When the options.contentMode is set to 'utf8' when the stream is created, the data argument must be a string. If the contentMode is set to 'buffer', the data argument must be a Buffer.
