Detailed Description
This datapoint type stores a UTF-8 (Unicode Transformation Format-8) string. The data length for one character can vary from 1 to 4 octets. Each character is encoded according to UTF-8.
This is a variable sized datapoint type.

Member Function Documentation
[protected] QKnxUtf8String::QKnxUtf8String(int subType, const char *string, int size)
Creates a variable sized datapoint type with the sub type subType that stores the string string with the length size.
QKnxUtf8String::QKnxUtf8String(const char *string, int size = -1)
Creates a variable sized datapoint type that stores the string string with the length size.
QKnxUtf8String::QKnxUtf8String(const QString &string)
Creates a variable sized datapoint type that stores the string string.
QKnxUtf8String::QKnxUtf8String()
Creates a variable sized datapoint type.
[override virtual] bool QKnxUtf8String::isValid() const
Reimplements: QKnxDatapointType::isValid() const.
bool QKnxUtf8String::setString(const QString &string)
Sets the string stored in the datapoint type to string.
If the value is outside the allowed range, returns false and does not set the string.
See also string().
bool QKnxUtf8String::setString(const char *string, int size = -1)
Sets the string stored in the datapoint type to string with the length size.
If size is -1, the full string is used.
If the string contains invalid UTF-8 sequences, returns false and does not set the string.
QString QKnxUtf8String::string() const
Returns the string stored in the datapoint type.
See also setString().
