Overlap of animations\n * Given that a CSS property cannot be animated in more than one place at the same time, it's\n * important that this behavior is detected and validated. The way in which this occurs is that\n * each time a style property is examined, a string-map containing the property will be updated with\n * the start and end times for when the property is used within an animation step.\n *\n * If there are two or more parallel animations that are currently running (these are invoked by the\n * group()) on the same element then the validator will throw an error. Since the start/end timing\n * values are collected for each property then if the current animation step is animating the same\n * property and its timing values fall anywhere into the window of time that the property is\n * currently being animated within then this is what causes an error.\n *\n * 2. Timing values\n * The validator will validate to see if a timing value of `duration delay easing` or\n * `durationNumber` is valid or not.\n *\n * (note that upon validation the code below will replace the timing data with an object containing\n * {duration,delay,easing}.\n *\n * 3. Offset Validation\n * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().\n * Offsets within keyframes() are considered valid when:\n *\n * - No offsets are used at all\n * - Each style() entry contains an offset value\n * - Each offset is between 0 and 1\n * - Each offset is greater to or equal than the previous one\n *\n * Otherwise an error will be thrown.\n */\nfunction buildAnimationAst(driver, metadata, errors, warnings) {\n return new AnimationAstBuilderVisitor(driver).build(metadata, errors, warnings);\n}\nconst ROOT_SELECTOR = '';\nclass AnimationAstBuilderVisitor {\n constructor(_driver) {\n this._driver = _driver;\n }\n build(metadata, errors, warnings) {\n const context = new AnimationAstBuilderContext(errors);\n this._resetContextStyleTimingState(context);\n const ast = (visitDslNode(this, normalizeAnimationEntry(metadata), context));\n if (typeof ngDevMode === 'undefined' || ngDevMode) {\n if (context.unsupportedCSSPropertiesFound.size) {\n pushUnrecognizedPropertiesWarning(warnings, [\n ...context.unsupportedCSSPropertiesFound.keys(),\n ]);\n }\n }\n return ast;\n }\n _resetContextStyleTimingState(context) {\n context.currentQuerySelector = ROOT_SELECTOR;\n context.collectedStyles = new Map();\n context.collectedStyles.set(ROOT_SELECTOR, new Map());\n context.currentTime = 0;\n }\n visitTrigger(metadata, context) {\n let queryCount = (context.queryCount = 0);\n let depCount = (context.depCount = 0);\n const states = [];\n const transitions = [];\n if (metadata.name.charAt(0) == '@') {\n context.errors.push(invalidTrigger());\n }\n metadata.definitions.forEach((def) => {\n this._resetContextStyleTimingState(context);\n if (def.type == AnimationMetadataType.State) {\n const stateDef = def;\n const name = stateDef.name;\n name\n .toString()\n .split(/\\s*,\\s*/)\n .forEach((n) => {\n stateDef.name = n;\n states.push(this.visitState(stateDef, context));\n });\n stateDef.name = name;\n }\n else if (def.type == AnimationMetadataType.Transition) {\n const transition = this.visitTransition(def, context);\n queryCount += transition.queryCount;\n depCount += transition.depCount;\n transitions.push(transition);\n }\n else {\n context.errors.push(invalidDefinition());\n }\n });\n return {\n type: AnimationMetadataType.Trigger,\n name: metadata.name,\n states,\n transitions,\n queryCount,\n depCount,\n options: null,\n };\n }\n visitState(metadata, context) {\n const styleAst = this.visitStyle(metadata.styles, context);\n const astParams = (metadata.options && metadata.options.params) || null;\n if (styleAst.containsDynamicStyles) {\n const missingSubs = new Set();\n const params = astParams || {};\n styleAst.styles.forEach((style) => {\n if (style instanceof Map) {\n style.forEach((value) => {\n extractStyleParams(value).forEach((sub) => {\n if (!params.hasOwnProperty(sub)) {\n missingSubs.add(sub);\n }\n });\n });\n }\n });\n if (missingSubs.size) {\n context.errors.push(invalidState(metadata.name, [...missingSubs.values()]));\n }\n }\n return {\n type: AnimationMetadataType.State,\n name: metadata.name,\n style: styleAst,\n options: astParams ?

If a sub\n * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n * merge the styles used within the sub timelines into itself (only with group() this will happen).\n * This happens with a merge operation (much like how the merge works in mergeSort) and it will only\n * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n * that if the styles are used later on in another phase of the animation then they will be the most\n * up-to-date values.\n *\n * [How Missing Styles Are Updated]\n * Each timeline has a `backFill` property which is responsible for filling in new styles into\n * already processed keyframes if a new style shows up later within the animation sequence.\n *\n * ```\n * sequence([\n * style({ width: 0 }),\n * animate(1000, style({ width: 100 })),\n * animate(1000, style({ width: 200 })),\n * animate(1000, style({ width: 300 }))\n * animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n * else\n * ])\n * ```\n *\n * What is happening here is that the `height` value is added later in the sequence, but is missing\n * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n * to properly fill in the style it will place the previous value (the value from the parent\n * timeline) or a default value of `*` into the backFill map.\n *\n * When a sub-timeline is created it will have its own backFill property. This is done so that\n * styles present within the sub-timeline do not accidentally seep into the previous/future timeline\n * keyframes\n *\n * [Validation]\n * The code in this file is not responsible for validation. That functionality happens with within\n * the `AnimationValidatorVisitor` code.\n */\nfunction buildAnimationTimelines(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles = new Map(), finalStyles = new Map(), options, subInstructions, errors = []) {\n return new AnimationTimelineBuilderVisitor().buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors);\n}\nclass AnimationTimelineBuilderVisitor {\n buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors = []) {\n subInstructions = subInstructions || new ElementInstructionMap();\n const context = new AnimationTimelineContext(driver, rootElement, subInstructions, enterClassName, leaveClassName, errors, []);\n context.options = options;\n const delay = options.delay ?

\n From time to time, govWorks (we, us or Company) may be required by law to provide to you certain written notices or\n disclosures. Described below are the terms and conditions for providing to you such notices and disclosures\n electronically through the govWorks system. Please read the information below carefully and thoroughly, and if you\n can access this information electronically to your satisfaction and agree to this Electronic Record and Signature\n Disclosure (ERSD), please confirm your agreement by selecting the check-box next to ‘I agree to use electronic\n records and signatures’ before clicking ‘CONTINUE’ within the govWorks system.\n\n
Getting paper copies
\n At any time, you may request from us a paper copy of any record provided or made available electronically to you by\n us. You will have the ability to download and print documents we send to you through the govWorks system during and\n immediately after the signing session and, if you elect to create a govWorks account, you may access the documents\n for a limited period of time (usually 30 days) after such documents are first sent to you. After such time, if you\n wish for us to send you paper copies of any such documents from our office to you, you will be charged a $0.00\n per-page fee. You may request delivery of such paper copies from us by following the procedure described below.\n\n\n
Withdrawing your consent
\n If you decide to receive notices and disclosures from us electronically, you may at any time change your mind and\n tell us that thereafter you want to receive required notices and disclosures only in paper format. How you must\n inform us of your decision to receive future notices and disclosure in paper format and withdraw your consent to\n receive notices and disclosures electronically is described below.\n\n\n
Consequences of changing your mind
\n If you elect to receive required notices and disclosures only in paper format, it will slow the speed at which we\n can complete certain steps in transactions with you and delivering services to you because we will need first to\n send the required notices or disclosures to you in paper format, and then wait until we receive back from you your\n acknowledgment of your receipt of such paper notices or disclosures. Further, you will no longer be able to use the\n govWorks system to receive required notices and consents electronically from us or to sign electronically documents\n from us.\n\n\n
All notices and disclosures will be sent to you electronically
\n Unless you tell us otherwise in accordance with the procedures described herein, we will provide electronically to\n you through the govWorks system all required notices, disclosures, authorizations, acknowledgements, and other\n documents that are required to be provided or made available to you during the course of our relationship with you.\n To reduce the chance of you inadvertently not receiving any notice or disclosure, we prefer to provide all of the\n required notices and disclosures to you by the same method and to the same address that you have given us. Thus, you\n can receive all the disclosures and notices electronically or in paper format through the paper mail delivery\n system. If you do not agree with this process, please let us know as described below. Please also see the paragraph\n immediately above that describes the consequences of your electing not to receive delivery of the notices and\n disclosures electronically from us.\n\n\n
How to contact govWorks:
\n You may contact us to let us know of your changes as to how we may contact you electronically, to request paper\n copies of certain information from us, and to withdraw your prior consent to receive notices and disclosures\n electronically as follows:\n To contact us by email send messages to: inquiries@govworks.com\n\n\n
To advise govWorks of your new email address
\n To let us know of a change in your email address where we should send notices and disclosures electronically to you,\n you must send an email message to us at inquiries@govworks.com and in the body of such request you must state:\n your\n previous email address, your new email address. We do not require any other information from you to change your\n email address.\n\n If you created a govWorks account, you may update it with your new email address through your account preferences.\n\n\n
To request paper copies from govWorks
\n To request delivery from us of paper copies of the notices and disclosures previously provided by us to you\n electronically, you must send us an email to inquiries@govworks.com and in the body of such request you must\n state\n your email address, full name, mailing address, and telephone number. We will bill you for any fees at that time, if\n any.\n\n\n
To withdraw your consent with govWorks
\n To inform us that you no longer wish to receive future notices and disclosures in electronic format you may:\n\n i. decline to sign a document from within your signing session, and on the subsequent page, select the check-box\n indicating you wish to withdraw your consent, or you may;\n ii. send us an email to inquiries@govworks.com and in the body of such request you must state your email, full\n name,\n mailing address, and telephone number. We do not need any other information from you to withdraw consent.. The\n consequences of your withdrawing consent for online documents will be that transactions may take a longer time to\n process..\n\n
