Defined in header <functional>
template< class T > struct logical_and;

Function object for performing logical AND (logical conjunction). Effectively calls operator&& on type T.

Member types

Type	Definition
result_type	bool
first_argument_type	T
second_argument_type	T

Member functions

operator()	returns the logical AND of the two arguments (public member function)

std::logical_and::operator()

bool operator()( const T& lhs, const T& rhs ) const;

Returns the logical AND of lhs and rhs.

Parameters

lhs, rhs

-

values to compute logical AND of

Return value

The result of lhs && rhs.

Exceptions

(none)

Possible implementation

bool operator()(const T &lhs, const T &rhs) const { return lhs && rhs; }
