BloombergLP::bdlcc::StripedUnorderedContainerImpl::setComputedValueAll

Serially invoke the specified visitor passing the specified key, and the address of the value of each element in this hash map having key. If key is not in the map, value will be default constructed. That is, for each (key, value) found, invoke: ` bool visitor(VALUE *value, const Key& key); ` If no element in the map has key, insert (key, VALUE()) and invoke visitor with value pointing to the defsult constructed value. Return the number of elements visited or the negation of that value if visitations stopped because visitor returned false. visitor, when invoked, has exclusive access (i.e., write access) to each element during each invocation. The behavior is undefined if hash map manipulators and getValue* methods are invoked from within visitor, as it may lead to a deadlock. Note that the setComputedValueFirst method is more performant than the when the hash map contains a single element for key. Also note that a return value of 0 implies that an element was inserted.
