provides functionality to enumerate the contents of a container.
An object that implements the XEnumeration interface
generates a series of elements, one at a time. Successive calls to
the XEnumeration::nextElement method return successive
elements of the series.
For example (Java), to print all elements of a vector aVect:
com::sun::star::lang::WrappedTargetException
If the implementation has internal reasons for exceptions,
then wrap these in a ::com::sun::star::lang::WrappedTargetException
exception.
