class BreakIterator;

// SharedBreakIterator encapsulates a shared BreakIterator. Because
// BreakIterator has mutable semantics, clients must ensure that all uses
// of a particular shared BreakIterator is protected by the same mutex
// ensuring that only one thread at a time gets access to that shared
// BreakIterator. Clients can accomplish this by creating a mutex for all
// uses of break iterator within a particular class. Then objects of that
// class may then freely share break iterators among themselves. However,
// these shared break iterators must never be exposed outside of that class.
