Detailed Description

template<typename ConcreteType, typename ResultType = ConcreteType>
class gko::EnablePolymorphicAssignment< ConcreteType, ResultType >

This mixin is used to enable a default PolymorphicObject::copy_from() implementation for objects that have implemented conversions between them.

The requirement is that there is either a conversion constructor from ConcreteType in ResultType, or a conversion operator to ResultType in ConcreteType.

Template Parameters
ConcreteTypethe concrete type from which the copy_from is being enabled [CRTP parameter]
ResultTypethe type to which copy_from is being enabled

Member Function Documentation

◆ convert_to()

template<typename ConcreteType, typename ResultType = ConcreteType>
void gko::EnablePolymorphicAssignment< ConcreteType, ResultType >::convert_to ( result_type *  result) const
inlineoverridevirtual

Converts the implementer to an object of type result_type.

Parameters
resultthe object used to store the result of the conversion

Implements gko::ConvertibleTo< ResultType >.

◆ move_to()

template<typename ConcreteType, typename ResultType = ConcreteType>
void gko::EnablePolymorphicAssignment< ConcreteType, ResultType >::move_to ( result_type *  result)
inlineoverridevirtual

Converts the implementer to an object of type result_type by moving data from this object.

This method is used when the implementer is a temporary object, and move semantics can be used.

Parameters
resultthe object used to emplace the result of the conversion
Note
ConvertibleTo::move_to can be implemented by simply calling ConvertibleTo::convert_to. However, this operation can often be optimized by exploiting the fact that implementer's data can be moved to the result.

Implements gko::ConvertibleTo< ResultType >.
