I have never used an uno::Sequence object before.  So, guessing from
the name, the object is a container object, holding a collection of
objects.  Some examples (assuming that my guess is correct) are below:

uno::Sequence<table::CellRangeAddress> collectionOfAddresses;
uno::Sequence<std::string> collectionOfStandardCppStrings;
struct IntegerWrapper {
  int value;
};
uno::Sequence<IntegerWrapper> collectionOfIntValues;
uno::Sequence<uno::Sequence<std::string>> collectionOfCollectionsOfStrings;

A container object affects neither the data type nor the functions of
the contained objects.  Instead, a container object provides
facilities to deal with a collection of objects, for example, to
iterate over all of the contained objects as illustrated below
(assuming my guess is correct tnat uno::Sequence class defines the
`begin' and `end' member functions):

uno::Sequence<std::string> collectionOfStandardCppStrings;
// fill in collectionOfStandardCppStrings with std::string objects
for (auto itr = collectionOfStandardCppStrings.begin();
     itr != collectionOfStandardCppStrings.end(); ++itr) {
  std::cout << *itr << '\n';
}
