The only way\n * to tell is if the `touchStart` occurred immediately after the\n * `onMomentumScrollEnd`.\n *\n * This is abstracted out for you, so you can just call this.scrollResponderIsAnimating() if\n * necessary\n *\n * `ScrollResponder` also includes logic for blurring a currently focused input\n * if one is focused while scrolling. The `ScrollResponder` is a natural place\n * to put this logic since it can support not dismissing the keyboard while\n * scrolling, unless a recognized \"tap\"-like gesture has occurred.\n *\n * The public lifecycle API includes events for keyboard interaction, responder\n * interaction, and scrolling (among others). The keyboard callbacks\n * `onKeyboardWill/Did/*` are *global* events, but are invoked on scroll\n * responder's props so that you can guarantee that the scroll responder's\n * internal state has been updated accordingly (and deterministically) by\n * the time the props callbacks are invoke. Otherwise, you would always wonder\n * if the scroll responder is currently in a state where it recognizes new\n * keyboard positions etc. If coordinating scrolling with keyboard movement,\n * *always* use these hooks instead of listening to your own global keyboard\n * events.\n *\n * Public keyboard lifecycle API: (props callbacks)\n *\n * Standard Keyboard Appearance Sequence:\n *\n * this.props.onKeyboardWillShow\n * this.props.onKeyboardDidShow\n *\n * `onScrollResponderKeyboardDismissed` will be invoked if an appropriate\n * tap inside the scroll responder's scrollable region was responsible\n * for the dismissal of the keyboard.

Therefore, `PanResponder` does not call\n * `onResponderMove` passed the first dispatch.

It analyzes\n * the geometry of elements, and observes when another responder (scroll view\n * etc) has stolen the touch lock. It notifies your component when it should\n * give feedback to the user. (bouncing/highlighting/unhighlighting).\n *\n * - When a touch was activated (typically you highlight)\n * - When a touch was deactivated (typically you unhighlight)\n * - When a touch was \"pressed\" - a touch ended while still within the geometry\n * of the element, and no other element (like scroller) has \"stolen\" touch\n * lock (\"responder\") (Typically you bounce the element).\n *\n * A good tap interaction isn't as simple as you might think. There should be a\n * slight delay before showing a highlight when starting a touch. If a\n * subsequent touch move exceeds the boundary of the element, it should\n * unhighlight, but if that same touch is brought back within the boundary, it\n * should rehighlight again. A touch can move in and out of that boundary\n * several times, each time toggling highlighting, but a \"press\" is only\n * triggered if that touch ends while within the element's boundary and no\n * scroller (or anything else) has stolen the lock on touches.\n *\n * To create a new type of component that handles interaction using the\n * `Touchable` mixin, do the following:\n *\n * - Initialize the `Touchable` state.\n *\n * getInitialState: function() {\n * return merge(this.touchableGetInitialState(), yourComponentState);\n * }\n *\n * - Choose the rendered component who's touches should start the interactive\n * sequence. On that rendered node, forward all `Touchable` responder\n * handlers. You can choose any rendered node you like. Choose a node whose\n * hit target you'd like to instigate the interaction sequence:\n *\n * // In render function:\n * return (\n * \n * \n * Even though the hit detection/interactions are triggered by the\n * wrapping (typically larger) node, we usually end up implementing\n * custom logic that highlights this inner one.\n * \n * \n * );\n *\n * - You may set up your own handlers for each of these events, so long as you\n * also invoke the `touchable*` handlers inside of your custom handler.\n *\n * - Implement the handlers on your component class in order to provide\n * feedback to the user. See documentation for each of these class methods\n * that you should implement.\n *\n * touchableHandlePress: function() {\n * this.performBounceAnimation(); // or whatever you want to do.\n * },\n * touchableHandleActivePressIn: function() {\n * this.beginHighlighting(...); // Whatever you like to convey activation\n * },\n * touchableHandleActivePressOut: function() {\n * this.endHighlighting(...); // Whatever you like to convey deactivation\n * },\n *\n * - There are more advanced methods you can implement (see documentation below):\n * touchableGetHighlightDelayMS: function() {\n * return 20;\n * }\n * // In practice, *always* use a predeclared constant (conserve memory).\n * touchableGetPressRectOffset: function() {\n * return {top: 20, left: 20, right: 20, bottom: 100};\n * }\n */\n\n/**\n * Touchable states.\n */\n\nvar States = {\n NOT_RESPONDER: 'NOT_RESPONDER',\n // Not the responder\n RESPONDER_INACTIVE_PRESS_IN: 'RESPONDER_INACTIVE_PRESS_IN',\n // Responder, inactive, in the `PressRect`\n RESPONDER_INACTIVE_PRESS_OUT: 'RESPONDER_INACTIVE_PRESS_OUT',\n // Responder, inactive, out of `PressRect`\n RESPONDER_ACTIVE_PRESS_IN: 'RESPONDER_ACTIVE_PRESS_IN',\n // Responder, active, in the `PressRect`\n RESPONDER_ACTIVE_PRESS_OUT: 'RESPONDER_ACTIVE_PRESS_OUT',\n // Responder, active, out of `PressRect`\n RESPONDER_ACTIVE_LONG_PRESS_IN: 'RESPONDER_ACTIVE_LONG_PRESS_IN',\n // Responder, active, in the `PressRect`, after long press threshold\n RESPONDER_ACTIVE_LONG_PRESS_OUT: 'RESPONDER_ACTIVE_LONG_PRESS_OUT',\n // Responder, active, out of `PressRect`, after long press threshold\n ERROR: 'ERROR'\n};\n/**\n * Quick lookup map for states that are considered to be \"active\"\n */\n\nvar IsActive = {\n RESPONDER_ACTIVE_PRESS_OUT: true,\n RESPONDER_ACTIVE_PRESS_IN: true\n};\n/**\n * Quick lookup for states that are considered to be \"pressing\" and are\n * therefore eligible to result in a \"selection\" if the press stops.\n */\n\nvar IsPressingIn = {\n RESPONDER_INACTIVE_PRESS_IN: true,\n RESPONDER_ACTIVE_PRESS_IN: true,\n RESPONDER_ACTIVE_LONG_PRESS_IN: true\n};\nvar IsLongPressingIn = {\n RESPONDER_ACTIVE_LONG_PRESS_IN: true\n};\n/**\n * Inputs to the state machine.\n */\n\nvar Signals = {\n DELAY: 'DELAY',\n RESPONDER_GRANT: 'RESPONDER_GRANT',\n RESPONDER_RELEASE: 'RESPONDER_RELEASE',\n RESPONDER_TERMINATED: 'RESPONDER_TERMINATED',\n ENTER_PRESS_RECT: 'ENTER_PRESS_RECT',\n LEAVE_PRESS_RECT: 'LEAVE_PRESS_RECT',\n LONG_PRESS_DETECTED: 'LONG_PRESS_DETECTED'\n};\n/**\n * Mapping from States x Signals => States\n */\n\nvar Transitions = {\n NOT_RESPONDER: {\n DELAY: States.ERROR,\n RESPONDER_GRANT: States.RESPONDER_INACTIVE_PRESS_IN,\n RESPONDER_RELEASE: States.ERROR,\n RESPONDER_TERMINATED: States.ERROR,\n ENTER_PRESS_RECT: States.ERROR,\n LEAVE_PRESS_RECT: States.ERROR,\n LONG_PRESS_DETECTED: States.ERROR\n },\n RESPONDER_INACTIVE_PRESS_IN: {\n DELAY: States.RESPONDER_ACTIVE_PRESS_IN,\n RESPONDER_GRANT: States.ERROR,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.RESPONDER_INACTIVE_PRESS_IN,\n LEAVE_PRESS_RECT: States.RESPONDER_INACTIVE_PRESS_OUT,\n LONG_PRESS_DETECTED: States.ERROR\n },\n RESPONDER_INACTIVE_PRESS_OUT: {\n DELAY: States.RESPONDER_ACTIVE_PRESS_OUT,\n RESPONDER_GRANT: States.ERROR,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.RESPONDER_INACTIVE_PRESS_IN,\n LEAVE_PRESS_RECT: States.RESPONDER_INACTIVE_PRESS_OUT,\n LONG_PRESS_DETECTED: States.ERROR\n },\n RESPONDER_ACTIVE_PRESS_IN: {\n DELAY: States.ERROR,\n RESPONDER_GRANT: States.ERROR,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.RESPONDER_ACTIVE_PRESS_IN,\n LEAVE_PRESS_RECT: States.RESPONDER_ACTIVE_PRESS_OUT,\n LONG_PRESS_DETECTED: States.RESPONDER_ACTIVE_LONG_PRESS_IN\n },\n RESPONDER_ACTIVE_PRESS_OUT: {\n DELAY: States.ERROR,\n RESPONDER_GRANT: States.ERROR,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.RESPONDER_ACTIVE_PRESS_IN,\n LEAVE_PRESS_RECT: States.RESPONDER_ACTIVE_PRESS_OUT,\n LONG_PRESS_DETECTED: States.ERROR\n },\n RESPONDER_ACTIVE_LONG_PRESS_IN: {\n DELAY: States.ERROR,\n RESPONDER_GRANT: States.ERROR,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.RESPONDER_ACTIVE_LONG_PRESS_IN,\n LEAVE_PRESS_RECT: States.RESPONDER_ACTIVE_LONG_PRESS_OUT,\n LONG_PRESS_DETECTED: States.RESPONDER_ACTIVE_LONG_PRESS_IN\n },\n RESPONDER_ACTIVE_LONG_PRESS_OUT: {\n DELAY: States.ERROR,\n RESPONDER_GRANT: States.ERROR,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.RESPONDER_ACTIVE_LONG_PRESS_IN,\n LEAVE_PRESS_RECT: States.RESPONDER_ACTIVE_LONG_PRESS_OUT,\n LONG_PRESS_DETECTED: States.ERROR\n },\n error: {\n DELAY: States.NOT_RESPONDER,\n RESPONDER_GRANT: States.RESPONDER_INACTIVE_PRESS_IN,\n RESPONDER_RELEASE: States.NOT_RESPONDER,\n RESPONDER_TERMINATED: States.NOT_RESPONDER,\n ENTER_PRESS_RECT: States.NOT_RESPONDER,\n LEAVE_PRESS_RECT: States.NOT_RESPONDER,\n LONG_PRESS_DETECTED: States.NOT_RESPONDER\n }\n};

Make sure all\n * your data is captured in the item data or external stores like Flux, Redux, or Relay.\n * - This is a `PureComponent` which means that it will not re-render if `props` remain shallow-\n * equal. Make sure that everything your `renderItem` function depends on is passed as a prop\n * (e.g. `extraData`) that is not `===` after updates, otherwise your UI may not update on\n * changes. This includes the `data` prop and parent component state.\n * - In order to constrain memory and enable smooth scrolling, content is rendered asynchronously\n * offscreen.

The UAC MUST treat the first session\n // description it receives as the answer, and MUST ignore any\n // session descriptions in subsequent responses to the initial\n // INVITE.\n //\n // o If the initial offer is in the first reliable non-failure\n // message from the UAS back to UAC, the answer MUST be in the\n // acknowledgement for that message (in this specification, ACK\n // for a 2xx response).\n //\n // o After having sent or received an answer to the first offer, the\n // UAC MAY generate subsequent offers in requests based on rules\n // specified for that method, but only if it has received answers\n // to any previous offers, and has not sent any offers to which it\n // hasn't gotten an answer.\n //\n // o Once the UAS has sent or received an answer to the initial\n // offer, it MUST NOT generate subsequent offers in any responses\n // to the initial INVITE.

Specifically, while a SIP INVITE request with an\n // initial offer may fork resulting in more than one provisional answer,\n // there is currently no easy/good way to to \"fork\" an offer generated\n // by a peer connection. In particular, a WebRTC offer currently may only\n // be matched with one answer and we have no good way to know which\n // \"provisional answer\" is going to be the \"final answer\". So we have\n // decided to punt and not create any \"early media\" sessions in this case.\n //\n // The upshot is that if you want \"early media\", you must not put the\n // initial offer in the INVITE. Instead, force the UAS to provide the\n // initial offer by sending an INVITE without an offer. In the WebRTC\n // case this allows us to create a unique peer connection with a unique\n // answer for every provisional offer with \"early media\" on all of them.\n ////\n ////\n // ROADMAP: The Offer/Answer Model Implementation\n //\n // The \"no early media if offer in INVITE\" implementation is not a\n // welcome one. The masses want it. The want it and they want it\n // to work for WebRTC (so they want to have their cake and eat too).\n //\n // So while we currently cannot make the offer in INVITE+forking+webrtc\n // case work, we decided to do the following...\n //\n // 1) modify SDH Factory to provide an initial offer without giving us the SDH, and then...\n // 2) stick that offer in the initial INVITE, and when 183 with initial answer is received...\n // 3) ask SDH Factory if it supports \"earlyRemoteAnswer\"\n // a) if true, ask SDH Factory to createSDH(localOffer).then((sdh) => sdh.setDescription(remoteAnswer)\n // b) if false, defer getting a SDH until 2xx response is received\n //\n // Our supplied WebRTC SDH will default to behavior 3b which works in forking environment (without)\n // early media if initial offer is in the INVITE). We will, however, provide an \"inviteWillNotFork\"\n // option which if set to \"true\" will have our supplied WebRTC SDH behave in the 3a manner.\n // That will result in\n // - early media working with initial offer in the INVITE, and...\n // - if the INVITE forks, the session terminating with an ERROR that reads like\n // \"You set 'inviteWillNotFork' to true but the INVITE forked. You can't eat your cake, and have it too.\"\n // - furthermore, we accept that users will report that error to us as \"bug\" regardless\n //\n // So, SDH Factory is going to end up with a new interface along the lines of...\n //\n // interface SessionDescriptionHandlerFactory {\n // makeLocalOffer(): Promise;\n // makeSessionDescriptionHandler(\n // initialOffer: ContentTypeAndBody, offerType: \"local\" | \"remote\"\n // ): Promise;\n // supportsEarlyRemoteAnswer: boolean;\n // supportsContentType(contentType: string): boolean;\n // getDescription(description: ContentTypeAndBody): Promise\n // setDescription(description: ContentTypeAndBody): Promise\n // }\n //\n // We should be able to get rid of all the hasOffer/hasAnswer tracking code and otherwise code\n // it up to the same interaction with the SDH Factory and SDH regardless of signaling scenario.\n ////\n // Send the INVITE request.\n\n\n this.outgoingInviteRequest = this.ua.userAgentCore.invite(this.request, {\n onAccept: function onAccept(inviteResponse) {\n return _this.onAccept(inviteResponse);\n },\n onProgress: function onProgress(inviteResponse) {\n return _this.onProgress(inviteResponse);\n },\n onRedirect: function onRedirect(inviteResponse) {\n return _this.onRedirect(inviteResponse);\n },\n onReject: function onReject(inviteResponse) {\n return _this.onReject(inviteResponse);\n },\n onTrying: function onTrying(inviteResponse) {\n return _this.onTrying(inviteResponse);\n }\n });\n };\n\n InviteClientContext.prototype.ackAndBye = function (inviteResponse, session, statusCode, reasonPhrase) {\n if (!this.ua.userAgentCore) {\n throw new Error(\"Method requires user agent core.\");\n }\n\n var extraHeaders = [];\n\n if (statusCode) {\n extraHeaders.push(\"Reason: \" + Utils_1.Utils.getReasonHeaderValue(statusCode, reasonPhrase));\n }\n\n var outgoingAckRequest = inviteResponse.ack();\n this.emit(\"ack\", outgoingAckRequest.message);\n var outgoingByeRequest = session.bye(undefined, {\n extraHeaders: extraHeaders\n });\n this.emit(\"bye\", outgoingByeRequest.message);\n };\n\n InviteClientContext.prototype.disposeEarlyMedia = function () {\n if (!this.earlyMediaSessionDescriptionHandlers) {\n throw new Error(\"Early media session description handlers undefined.\");\n }\n\n this.earlyMediaSessionDescriptionHandlers.forEach(function (sessionDescriptionHandler) {\n sessionDescriptionHandler.close();\n });\n };\n /**\n * Handle final response to initial INVITE.\n * @param inviteResponse 2xx response.\n */\n\n\n InviteClientContext.prototype.onAccept = function (inviteResponse) {\n var _this = this;\n\n if (!this.earlyMediaSessionDescriptionHandlers) {\n throw new Error(\"Early media session description handlers undefined.\");\n }\n\n var response = inviteResponse.message;\n var session = inviteResponse.session; // Our transaction layer is \"non-standard\" in that it will only\n // pass us a 2xx response once per branch, so there is no need to\n // worry about dealing with 2xx retransmissions.
