nl_tokens: Instantiate a new FileQueue . Pass in the maximum number of files to be opened at any one time . By default it attempts to return an already instantiated instance of FileQueue so that your maxfiles is shared across processes However by setting the newQueue to true you can request an entirely new queue ( and one that won t be returned to any other instantiators )
pl_tokens: function FileQueue ( limit , newQueue ) { if ( typeof <mask> === 'boolean' ) { newQueue = limit ; limit = null ; } if ( ! limit ) { limit = 200 ; // default file queue limit of 200, based on normal maxfiles of 256 } // if there is already an instance of FileQueue running, update the limit and return it if ( fq instanceof FileQueue && ! newQueue ) { if ( limit > fq . limit ) { fq . limit = limit ; } return fq ; } this . limit = limit ; this . queue = [ ] ; this . openFiles = 0 ; // create a reference to the instance to be accessed again if ( ! newQueue ) { fq = this ; } return this ; }
