is_hash
Function Details
bool is_hash() const
Get container category.
Determines whether this container object is a std::map<> equivalent(when returns false) or that of hash_map<> class(when returns true). This method is not in stl, but it may be called by users because some operations are not supported by both type(map/hash_map) of containers, you need to call this function to distinguish the two types. dbstl will not stop you from calling the wrong methods of this class.
Return Value
Returns true if this container is a hash container based on a Berkeley DB hash database; returns false if it is based on a Berkeley DB btree database.
