Declared in <bdlc_flathashtable.h>

Create an table having the same value as the specified original object by moving (in constant time) the contents of original to the new table. Use a copy of original.hash_function() to generate hash values for the keys of the entries contained in this table. Use a copy of original.key_eq() to verify that two keys are equal. The allocator associated with original is propagated for use in the newly‐created table. original is left in a (valid) unspecified state.

explicit
FlatHashTable(bslmf::MovableRef<FlatHashTable> original);

Create a table having the same value, hasher, and key‐equality comparator as the specified original object by moving the contents of original to the new table, and using the specified basicAllocator to supply memory. Use a copy of original.hash_function() to generate hash values for the entries contained in this table. Use a copy of original.key_eq() to verify that the keys of two entries are equal. This method requires that the (template parameter) type ENTRY be move‐insertable into this FlatHashTable. If basicAllocator is 0, the currently installed default allocator is used. If original and the newly created object have the same allocator then the value of original becomes unspecified but valid, and no exceptions will be thrown; otherwise original is unchanged (and an exception may be thrown).

FlatHashTable(
    bslmf::MovableRef<FlatHashTable> original,
    bslma::Allocator* basicAllocator);

Create a table having the same value, hasher, and key‐equality comparator as the specified original. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used.

FlatHashTable(
    FlatHashTable const& original,
    bslma::Allocator* basicAllocator = 0);

Create an empty table having at least the specified capacity, that will use the specified hash to generate hash values for the keys of the entries contained in this table, and the specified equal to verify that the keys of the two entries are the same. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. If 0 == capacity, no memory is allocated and the object is defined to be in the "zero‐capacity" state.

FlatHashTable(
    std::size_t capacity,
    HASH const& hash,
    EQUAL const& equal,
    bslma::Allocator* basicAllocator = 0);
