GeolocationPermission

This class is used to manage permissions for the WebView's Geolocation JavaScript API. Geolocation permissions are applied to an origin, which consists of the host, scheme and port of a URI. In order for web content to use the Geolocation API, permission must be granted for that content's origin. This class stores Geolocation permissions. An origin's permission state can be either allowed or denied. This class uses Strings to represent an origin. When an origin attempts to use the Geolocation API, but no permission state is currently set for that origin, UltimateWebChromeClient's GeolocationPermissionsRequest event is called. This allows the permission state to be set for that origin. The methods of this class can be used to modify and interrogate the stored Geolocation permissions at any time.

Events:

• GetOriginsResult (Origins As List)
• IsAllowedResult (Allowed As Boolean)

Functions:

• Allow (Origin As String)
  Allows the specified origin to use the Geolocation API.

  This method is asynchronized. When result become available, event "GetOriginsResult" will be fired. Use WaitFor for synchronized result.
• Initialize (EventName As String)
  
• IsAllowed (Origin As String)
  Gets the Geolocation permission state for the specified origin.
  Origin: the origin for which Geolocation permission is requested

• SetRendererPriorityPolicy (RendererRequestedPriority As Int, WaivedWhenNotVisible As Boolean)
  Set the renderer priority policy for this WebView. The priority policy will be used to determine whether an out of process renderer should be considered to be a target for OOM killing. Because a renderer can be associated with more than one WebView, the final priority it is computed as the maximum of any attached WebViews. When a WebView is destroyed it will cease to be considerered when calculating the renderer priority. Once no WebViews remain associated with the renderer, the priority of the renderer will be reduced to RENDERER_PRIORITY_WAIVED. The default policy is to set the priority to RENDERER_PRIORITY_IMPORTANT regardless of visibility, and this should not be changed unless the caller also handles renderer crashes. Any other setting will result in WebView renderers being killed by the system more aggressively than the application.
  RendererRequestedPriority: the minimum priority at which this WebView desires the renderer process to be bound. Value is RENDERER_PRIORITY_WAIVED, RENDERER_PRIORITY_BOUND, or RENDERER_PRIORITY_IMPORTANT.
  WaivedWhenNotVisible: if true, this flag specifies that when this WebView is not visible, it will be treated as if it had requested a priority of RENDERER_PRIORITY_WAIVED.
