BloombergLP::bdlcc::StripedUnorderedMap::insert

Insert or update using the move‐insertable value for key.

Synopsis

Declared in <bdlcc_stripedunorderedmap.h>

std::size_t
insert(
    KEY const& key,
    bslmf::MovableRef<VALUE> value);

Description

If key already exists in this hash map, the value attribute of that element is set to value. Return 1 if an element is inserted, and 0 if an existing element is updated. The value object is left in a valid but unspecified state. If value is allocator‐enabled and allocator() != value.allocator() this operation may cost as much as a copy. Note that the return value equals the number of elements inserted.

Return Value

1 if an element is inserted, and 0 if an existing element is updated

Parameters

Description
