Public Functions

virtual void Add(T value) noexcept = 0

Add adds the value to the counter’s sum

Parameters:

value – The increment amount. MUST be non-negative.

virtual void Add(T value, const context::Context &context) noexcept = 0

virtual void Add(T value, const common::KeyValueIterable &attributes) noexcept = 0

Add adds the value to the counter’s sum. The attributes should contain the keys and values to be associated with this value. Counters only accept positive valued updates.

Parameters:

• value – The increment amount. MUST be non-negative.

• attributes – the set of attributes, as key-value pairs
