Methods

Add(T)	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Add(T, KeyValuePair<String,Object>)	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Add(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Add(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Add(T, KeyValuePair<String,Object>[])	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Add(T, ReadOnlySpan<KeyValuePair<String,Object>>)	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Add(T, TagList)	Records the delta value of the measurement. The delta can be positive, negative, or zero.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Publish()	Activates the instrument to start recording measurements and to allow listeners to start listening to such measurements. (Inherited from Instrument)
RecordMeasurement(T)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
RecordMeasurement(T, KeyValuePair<String,Object>)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
RecordMeasurement(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
RecordMeasurement(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
RecordMeasurement(T, ReadOnlySpan<KeyValuePair<String,Object>>)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
RecordMeasurement(T, TagList)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
ToString()	Returns a string that represents the current object. (Inherited from Object)
