Detailed Description

template<typename T>
struct ecuda::owner_less< shared_ptr< T > >

This function object provides owner-based (as opposed to value-based) mixed-type ordering of ecuda::shared_ptr. The order is such that two smart pointers compare equivalent only if they are both empty or if they both manage the same object, even if the values of the raw pointers obtained by get() are different (e.g. because they point at different subobjects within the same object).

This class template is the preferred comparison predicate when building associative containers with ecuda::shared_ptr as keys, that is: std::map< ecuda::shared_ptr<T>, U, ecuda::owner_less<ecuda::shared_ptr<T> > >.

Member Function Documentation

template<typename T >

__HOST__ __DEVICE__ bool ecuda::owner_less< shared_ptr< T > >::operator() ( const shared_ptr< T > &  lhs, const shared_ptr< T > &  rhs  ) const

inline

Compares lhs and rhs using owner-based semantics.

Parameters

lhs,rhs

Returns

true if lhs is less than rhs as determined by the owner-based ordering
