nl_tokens: A small set of propagation patterns each of which will accept a small amount of information and generate a set of dispatch ready event objects - which are sets of events that have already been annotated with a set of dispatched listener functions / ids . The API is designed this way to discourage these propagation strategies from actually executing the dispatches since we always want to collect the entire set of dispatches before executing even a single one . Tags a SyntheticEvent with dispatched listeners . Creating this function here allows us to not have to bind or create functions for each event . Mutating the event s members allows us to not have to create a wrapping dispatch object that pairs the event with the listener .
pl_tokens: function accumulateDirectionalDispatches ( inst , <mask> , event ) { { ! inst ? warningWithoutStack$1 ( false , 'Dispatching inst must not be null' ) : void 0 ; } var listener = listenerAtPhase ( inst , event , phase ) ; if ( listener ) { event . _dispatchListeners = accumulateInto ( event . _dispatchListeners , listener ) ; event . _dispatchInstances = accumulateInto ( event . _dispatchInstances , inst ) ; } }
