Create an unordered set by moving original, using basicAllocator.

Synopsis

Declared in <bslstl_unorderedset.h>

unordered_set(
    BloombergLP::bslmf::MovableRef<unordered_set> original,
    ALLOCATOR const& basicAllocator);

Description

Create an unordered set having the same value as the specified original object that uses the specified basicAllocator to supply memory. The contents of original are moved (in constant time) to the new set if basicAllocator == original.get_allocator(), and are move‐inserted (in linear time) using basicAllocator otherwise. original is left in a valid but unspecified state. Use a copy of original.hash_function() to generate hash values for the keys contained in this set. Use a copy of original.key_eq() to verify that two keys are equivalent. This method requires that the (template parameter) type KEY be move‐insertable (see {Requirements on KEY}). Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) type ALLOCATOR is bsl::allocator (the default).
