Call visitor on the element having key, if present.
Declared in <bdlcc_stripedunorderedmap.h>
int
update(
KEY const& key,
VisitorFunction const& visitor);That is: ` bool visitor(&value, key); ` Return the number of elements updated or -1 if visitor returned false. visitor has exclusive access (i.e., write access) the element for during its invocation. The behavior is undefined if hash map manipulators and getValue* methods are invoked from within visitor, as it may lead to a deadlock.
DEPRECATED: Use visit(key, visitor) instead.
