BloombergLP::bdlb::operator==

Return true if the specified lhs and rhs objects have the same value, and false otherwise. A nullable object and a value of some type have the same value if the nullable object is non-null and its underlying value compares equal to the other value. Note that this function will fail to compile if LHS_TYPE and RHS_TYPE are not compatible.
