*Summary*
--------
+ comphelper/scopeguard.hxx: class FlagGuard
*Description*
-------------
The new class ::comphelper::FlagGuard, defined in
comphelper/scopeguard.hxx, is a specialization of
::comphelper::ScopeGuard, implementing the pattern (seen multiple
times all around the code) of resetting a flag when leaving a scope.
I.e.
{
someFlag = true;
FlagGuard aGuard( someFlag );
...
}
will ensure that at the end of the scope, "someFlag" has the value
"false", no matter how and where the scope is left.
