Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetInstallabilityErrorsAsync
GetInstallabilityErrors
Public methodGetLayoutMetricsAsync
Returns metrics relating to the layouting of the page, such as viewport bounds/scale.

GetManifestIcons
Public methodGetNavigationHistoryAsync
Returns navigation history for the current page.
Public methodGetOriginTrialsAsync

Public methodGetPermissionsPolicyStateAsync
Get Permissions Policy state on given frame.
Public methodGetResourceContentAsync
Returns content of the given resource.

Public methodProduceCompilationCacheAsync
Requests backend to produce compilation cache for the specified scripts. Unlike setProduceCompilationCache, this allows client to only produce cache for specific scripts. `scripts` are appeneded to the list of scripts for which the cache for would produced. Disabling compilation cache with `setProduceCompilationCache` would reset all pending cache requests. The list may also be reset during page navigation. When script with a matching URL is encountered, the cache is optionally produced upon backend discretion, based on internal heuristics. See also: `Page.compilationCacheProduced`.
Public methodReloadAsync
Reloads given page optionally ignoring the cache.
Public methodRemoveScriptToEvaluateOnNewDocumentAsync
Removes given script from the list.
