template< typename T1 , typename T2 , typename T3 = unspecified ... , typename Tn = unspecified > struct bitxor_ { typedef unspecified type; };
Returns the result of bitwise xor (^) operation of its arguments.
#include <boost/mpl/bitxor.hpp> #include <boost/mpl/bitwise.hpp>
Parameter | Requirement | Description |
---|---|---|
T1, T2,... Tn | Integral Constant | Operation's arguments. |
[Note: The requirements listed in this specification are the ones imposed by the default implementation. See Numeric Metafunction concept for the details on how to provide an implementation for a user-defined numeric type that does not satisfy the Integral Constant requirements. — end note]
For any Integral Constants c1,c2,... cn:
typedef bitxor_...cn>::type r;
Return type: | |
---|---|
Semantics: | Equivalent to typedef integral_c< typeof(c1::value ^ c2::value) , ( c1::value ^ c2::value ) > c; typedef bitxor_ |
typedef bitxor_...cn> r;
Return type: | |
---|---|
Semantics: | Equivalent to struct r : bitxor_ |
Amortized constant time.
