Visit each element with key read‐only via the specified visitor.

Synopsis

Declared in <bdlcc_stripedunorderedcontainerimpl.h>

int
visitReadOnly(
    KEY const& key,
    ReadOnlyVisitorFunction const& visitor) const;

Description

Serially call the specified visitor on each element (if one exists) in this hash map having the specified key until every such element has been visited or visitor returns false. That is, for (key, value), invoke: ` bool visitor(value, key); ` Return the number of elements visited or the negation of that value if visitations stopped because visitor returned false. visitor has read‐only access to each element for duration of each invocation. The behavior is undefined if hash map manipulators are invoked from within visitor, as it may lead to a deadlock.

Return Value

number of elements visited, or its negation if stopped early

Parameters

Name

Description

key

key of the elements to visit

visitor

functor invoked with each matching value
