详细描述

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 () 等于 2^(step code -1) .

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

`[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 .

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

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

QKnx3BitControlled:: QKnx3BitControlled ()

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

bool QKnx3BitControlled:: controlBit () const

Returns the control stored in the datapoint type.

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

重实现： QKnxDatapointType::isValid () const.

QKnx3BitControlled::NumberOfIntervals QKnx3BitControlled:: numberOfIntervals () const

Returns the number of intervals stored in the datapoint type.
