class CounterDatapointRemoteObject

File Information

Library: IoT/Devices
Package: Generated
Header: IoT/Devices/CounterDatapointRemoteObject.h

Description

The base class for datapoints holding a counter (a 64-bit unsigned integer).

In addition to the methods defined in this interface, a CounterDatapoint implementation should expose the following properties:

  • displayValue (string, optional): The current value of the datapoint, formatted as string for display purposes.

);

Updates the counter and returns the new value.

Not all CounterDatapoint implementations may support this method.

See also: IoT::Devices::ICounterDatapoint::increment()

invalidate virtual inline

virtual void invalidate();

Invalidates the datapoint's value.

Subsequent calls to valid() will return false, until a new value has been set.

valid virtual inline

virtual bool valid() const;

Returns true if a valid value is available.

Note that between the time valid() is called and a subsequent call to value() or similar method, the validity may change. Use validValue() or similar methods of subclasses to atomically get validity and value.

validValue virtual inline

Poco::Optional < Poco::Int64 > validValue() const;

Returns the current value of the datapoint if it is valid, otherwise an empty value.
