public void StartDoubleState(string name, double value, AppCaptureMetadataPriority priority);

function startDoubleState(name, value, priority)

Public Sub StartDoubleState (name As String, value As Double, priority As AppCaptureMetadataPriority)

Parameters

name: String
Platform::String

winrt::hstring

The name of the metadata state.

value: Double
double

The value of the metadata state.

priority: AppCaptureMetadataPriority

A member of the AppCaptureMetadataPriority enumeration specifying the relative importance of the metadata item. This value and the age of a metadata item are used by the system to determine which metadata items should be purged first when the limit of the allocated storage space for accumulated metadata is reached.

Remarks

The system associates a metadata state with the window of time between when the state is started and when its value is changed or the state is stopped with a call to StopAllStates. To store a double value that applies to an instantaneous moment in time, use AddDoubleEvent.
