Detailed Description

The QKnx3BitControlled class is a datapoint type with a control part.

This is a fixed size datapoint type with the length of 1 byte, though only 4 bits are used by the actual implementation.

Of the 4 bits, 3 bits are reserved for the step code and 1 bit for the control part. The step code allows for the calculation of the number of intervals, so that numberOfIntervals() equals 2^(step code -1).

To set this datapoint type, the control and the NumberOfIntervals have to be set.

See also QKnxDatapointType and Qt KNX Datapoint Type Classes.

Member Function Documentation

QKnx3BitControlled::QKnx3BitControlled()

Creates a fixed size datapoint type with the control part set to false and the number of intervals set to Break.

QKnx3BitControlled::QKnx3BitControlled(bool control, QKnx3BitControlled::NumberOfIntervals n)

Creates a fixed size datapoint type with the control control and the number of intervals n.

[protected] QKnx3BitControlled::QKnx3BitControlled(int subType, bool control, QKnx3BitControlled::NumberOfIntervals n)

Creates a fixed size datapoint type with subtype subType, control control, and number of intervals n.

bool QKnx3BitControlled::controlBit() const

Returns the control stored in the datapoint type.

See also setControlBit().

[override virtual] bool QKnx3BitControlled::isValid() const

Reimplemented from QKnxDatapointType::isValid().

QKnx3BitControlled::NumberOfIntervals QKnx3BitControlled::numberOfIntervals() const

Returns the number of intervals stored in the datapoint type.

See also setNumberOfIntervals().

void QKnx3BitControlled::setControlBit(bool value)

Sets the control part of the datapoint type to value.

If the value is outside the allowed range, returns false and does not set the value.

See also controlBit().

bool QKnx3BitControlled::setNumberOfIntervals(QKnx3BitControlled::NumberOfIntervals n)

Sets the number of intervals to n.

If the value is outside the allowed range, returns false and does not set the value.

See also numberOfIntervals().
