Detailed Description

template<typename T, typename = void>
struct piranha::math::is_unitary_impl< T, typename >

Default functor for the implementation of piranha::math::is_unitary().

This functor should be specialised via the std::enable_if mechanism. The default implementation defines a call operator which is enabled only if the argument type is constructible from the C++ int type and T is equality comparable.

Member Function Documentation

operator()()

template<typename T , typename = void>

template<typename U , enabler< U > = 0>

bool piranha::math::is_unitary_impl< T, typename >::operator() ( const U &  x ) const

inline

Call operator.

Note

This template method is enabled only if U can be constructed from int and U is equality comparable.

The operator will compare x to an instance of U constructed from the literal 1.

Parameters

x	argument to be tested.

Returns

true if x is equal to 1, false otherwise.

Exceptions

unspecified

any exception thrown by the construction or comparison of instances of type U or by the conversion of the result to bool.
