◆ find() [1/2]

ConstElementPtr isc::data::MapElement::find ( const std::string & identifier ) const

overridevirtual

Recursively finds any data at the given identifier.

The identifier is a /-separated list of names of nested maps, with the last name being the leaf that is returned.

For instance, if you have a MapElement that contains another MapElement at the key "foo", and that second MapElement contains Another Element at key "bar", the identifier for that last element from the first is "foo/bar".

Parameters

identifier The identifier of the element to find

Returns: The ElementPtr at the given identifier. Returns a null ElementPtr if it is not found, which can be checked with Element::is_null(ElementPtr e).
