Detailed Description

Function Documentation

tribool boost::logic::operator! ( tribool  x )

inline

#include <boost_1_57_0/boost/logic/tribool.hpp>

Computes the logical negation of a tribool.

Returns

the logical negation of the tribool, according to the table:

!
false	true
true	false
indeterminate	indeterminate

Exceptions

nothrow

tribool boost::logic::operator&& ( tribool  x, tribool  y  )

inline

#include <boost_1_57_0/boost/logic/tribool.hpp>

Computes the logical conjuction of two tribools.

Returns

the result of logically ANDing the two tribool values, according to the following table:

&&	false	true	indeterminate
false	false	false	false
true	false	true	indeterminate
indeterminate	false	indeterminate	indeterminate

Exceptions

nothrow
