Public Methods

Method	Description
CheckDataFileRefresh ( object state ) : void	Checks if the data file has been updated and refreshes if it has.
Download ( ) : LicenceKeyResults	Checks for a new version of the data file if licence keys are available.
Refresh ( ) : void	Forces the application to reload the active provider on the next request.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Disposes of the DataSet if one is available.

Private Methods

Method	Description
CheckDataFileHasRefreshed ( FiftyOne.Foundation.Mobile.Detection.Entities.DataSet dataSet ) : bool	Returns true if a newer data set is now available.
CleanTemporaryFiles ( ) : void	Cleans up any temporary files that remain from previous providers.
Create ( ) : WebProvider	Forces the provider to update current ActiveProvider with new data.
CreateNewTemporaryFile ( FileInfo masterFile ) : FileInfo	Create a new temporary file for use the stream factory.
GetActiveProvider ( ) : WebProvider	A reference to the active provider.
GetContextItems ( HttpRequest request ) : System.Collections.IDictionary	Returns a collection that can be used to persist data across the request. If using .NET 4 or above the HttpRequest context items collection is used. If lower versions then the current context, if it exists is used. If there is no collection available then null is returned and the requesting routine will need to work without the benefit of persisting the detection result across the request. The implementation varies by .NET version.
GetDataFileDate ( string fileName ) : DateTime?	Creates a stream data set for the file provided and returns the published data of the file. Throws an exception if there's a problem accessing the file.
GetMatch ( HttpRequest request ) : Match	Returns the match results for the request, or creates one if one does not already exist. If the match has already been calculated it is fetched from the context items collection.
GetRequiredHeaders ( HttpRequest request ) : NameValueCollection	Gets the required headers. If the MVC method SetBrowserOverride has been used the User-Agent will be escapted and may contain + characters which need to be removed. Requests after SetOverrideBrowser are still expected to use the overriden alias. The override useragent is stored in cookie which ASP.NET unpacks automatically, however it is url encoded with pluses instead of spaces. This code transforms the useragent back, but a new NameValueCollection is needed as the original collection cannot be modified.
GetTempFileDataSet ( ) : FiftyOne.Foundation.Mobile.Detection.Entities.DataSet	Returns a data set initialised with a temporary data file. If an existing one is present that can be used then it will be favoured. If a new one is needed then one will be created.
GetTempFileName ( ) : string	Returns a temporary file name for the data file.
OnProcessExit ( object sender, EventArgs e ) : void	The application is being disposed of either due to a recycle event or shutdown. Ensure the active provider is disposed of to release resources.
WebProvider ( FiftyOne.Foundation.Mobile.Detection.Entities.DataSet dataSet ) : System	Constructs a new instance of the provider with the data set supplied.
