    Inherits Attribute

Remarks

This attribute is intended to be applied to all classes that inherit from the Switch class. The purpose of the attribute is to identify the type that specifies the switch criteria of the switch. Each switch determines whether a trace is to be written, based on whether an event type matches or exceeds the value of the SwitchLevelType property for the switch. The type used for the SwitchLevelType property varies for different switches. For example, the switch level type for the BooleanSwitch class is Boolean, and the switch level type for the TraceSwitch class is TraceLevel.
