[protected] QKnxCharString::QKnxCharString(int subType, const char *string, int size)

Creates a fixed size datapoint type with the subtype subType, storing the string string with the length size.

QKnxCharString::QKnxCharString(const char *string, int size = -1)

Creates a fixed size datapoint type storing the string string with the length size.

QKnxCharString::QKnxCharString(QLatin1String string)

Creates a fixed size datapoint type storing the string string.

QKnxCharString::QKnxCharString()

Creates a fixed size datapoint type with the value set to 0.

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

Reimplements: QKnxDatapointType::isValid() const.

bool QKnxCharString::setString(QLatin1String string)

Sets the string stored in the datapoint type to string.

Returns true if the value was set; otherwise returns false.

See also string().

bool QKnxCharString::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 value is outside the allowed range, returns false and does not set the string.

QLatin1String QKnxCharString::string() const

Returns the string stored in the datapoint type.
