`[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

重实现： 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.

bool QKnxUtf8String:: setString (const char * string , int size = -1)

Sets the string stored in the datapoint type to string with the length size .

若 size is -1 , the full string 被使用。

If the string contains invalid UTF-8 sequences, returns false and does not set the string.

QString QKnxUtf8String:: string () const
