+/** A wrapper for a UNO property set.
+
+ This class provides functions to silently get and set properties (without
+ exceptions, without the need to check validity of the UNO property set).
+
+ An instance is constructed with the reference to a UNO property set or any
+ other interface (the constructor will query for the
+ com.sun.star.beans.XPropertySet interface then). The reference to the
+ property set will be kept as long as the instance of this class is alive.
+
+ The functions setProperties() tries to handle all passed values at once,
+ using the com.sun.star.beans.XMultiPropertySet interface. If the
+ implementation does not support the XMultiPropertySet interface, all
+ properties are handled separately in a loop.
