Member Function Documentation

◆ GetDataDownloadType()

override string FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.GetDataDownloadType

(

string

identifier

)

Get the value to use for the 'Type' parameter when calling the 51Degrees Distributor service to check for a newer data file.

Parameters: identifier - The identifier of the data file to get the type for. This engine only uses one file so this parameter is ignored.

Returns: A string

◆ ProcessEngine()

override void FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.ProcessEngine	(	IFlowData	data,
		IDeviceDataHash	deviceData
	)

protected

Perform processing for this engine

Parameters: data - The IFlowData instance containing data for the current request.; deviceData - The IDeviceDataHash instance to populate with property values

Exceptions: ArgumentNullException - Thrown if a required parameter is null

◆ RefreshData() [1/2]

override void FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.RefreshData

(

string

dataFileIdentifier

)

Called when update data is available in order to get the engine to refresh it's internal data structures.

This overload is used if the data is a physical file on disk.

Parameters: dataFileIdentifier - The identifier of the data file to update. This engine only uses one data file so this parameter is ignored.

◆ RefreshData() [2/2]

override void FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.RefreshData	(	string	dataFileIdentifier,
		Stream	stream
	)

Called when update data is available in order to get the engine to refresh it's internal data structures.

This overload is used when the data is presented as a Stream, usually a MemoryStream.

Parameters: dataFileIdentifier - The identifier of the data file to update. This engine only uses one data file so this parameter is ignored.; stream - The Stream containing the data to refresh the engine with.

◆ UnmanagedResourcesCleanup()

override void FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.UnmanagedResourcesCleanup

(

)

protected

Dispose of any unmanaged resources.

Member Data Documentation

◆ AutomaticUpdatesEnabled

bool FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.AutomaticUpdatesEnabled => _engine.getAutomaticUpdatesEnabled()

True if the data used by this engine will automatically be updated when a new file is available.

False if the data will only be updated manually.

◆ DataSourceTier

override string FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.DataSourceTier => _engine.getType()

The tier of the data that is currently being used by this engine.

For example, 'Lite' or 'Enterprise'

◆ ElementDataKey

override string FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.ElementDataKey => "device"

The key to use for this element's data in a IFlowData instance.

◆ EvidenceKeyFilter

override IEvidenceKeyFilter FiftyOne.DeviceDetection.Hash.Engine.OnPremise.FlowElements.DeviceDetectionHashEngine.EvidenceKeyFilter => _evidenceKeyFilter

A filter that defines the evidence that this engine can make use of.
