An Object of this class provides a characteristic to be added to a QLowEnergyServiceData object via QLowEnergyServiceData::addCharacteristic ().

Constructs a new object of this class that is a copy of other .
Creates a new invalid object of this class.
Makes this object a copy of other and returns the new value of this object.
销毁此对象。
添加 descriptor to the list of descriptors of this characteristic, if it is valid.

Returns the descriptors of this characteristic.
另请参阅 setDescriptors ().
Returns true if and only if this characteristic is valid, that is, it has a non-null UUID.
Returns the maximum length in bytes that the value of this characteristic can have. By default, there is no limit beyond the constraints of the data type.
Returns the minimum length in bytes that the value of this characteristic can have. The default is zero.
Returns the properties of this characteristic.
另请参阅 setProperties ().
Returns the constraints needed for a client to read the value of this characteristic. If properties () does not include QLowEnergyCharacteristic::Read , this value is irrelevant. By default, there are no read constraints.
另请参阅 setReadConstraints ().
Sets the descriptors of this characteristic to descriptors . Only valid descriptors are considered.
另请参阅 descriptors () 和 addDescriptor ().
Sets the properties of this characteristic to properties .
另请参阅 properties ().
Specifies that clients need to fulfill constraints to read the value of this characteristic.
另请参阅 readConstraints ().
Sets the UUID of this characteristic to uuid .
另请参阅 uuid ().
Sets the value of this characteristic to value .
另请参阅 value ().
Specifies minimum and maximum to be the smallest and largest length, respectively, that the value of this characteristic can have. The unit is bytes. If minimum and maximum are equal, the characteristic has a fixed-length value.
Specifies that clients need to fulfill constraints to write the value of this characteristic.
另请参阅 writeConstraints ().
Swaps this object with other .
Returns the UUID of this characteristic.
另请参阅 setUuid ().
Returns the value of this characteristic.
另请参阅 setValue ().
Returns the constraints needed for a client to write the value of this characteristic. If properties () does not include either of QLowEnergyCharacteristic::Write , QLowEnergyCharacteristic::WriteNoResponse and QLowEnergyCharacteristic::WriteSigned , this value is irrelevant. By default, there are no write constraints.
