Adds a new double metadata state.
public:
void StartStringState(
String^ name,
String^ value,
AppCaptureMetadataPriority priority
)
name
Type: String
The name of the metadata state.
value
Type: String
The value of the metadata state.
priority
Type: 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.
The system associates a metadata state with the window of time between when the state is started and when it’s value is changed or the state is stopped with a call to StopAllStates. To store a string value that applies to an instantaneous moment in time, use AddStringEvent.
