Detailed Description

template<class Interface>
class Dune::Functions::PolymorphicType< Interface >

Base class with polymorphic type boiler plate code.

By deriving your polymorphic type from this class you enforce a default interface for common operations like clone, clone to buffer, and move.

Member Function Documentation

clone() [1/2]

template<class Interface >

virtual Interface * Dune::Functions::PolymorphicType< Interface >::clone ( ) const

pure virtual

Clones the object.

clone() needs to be redefined by an implementation class, with the return type covariantly adapted. This will return a new copy of *this via a pointer to newly allocated memory. Remember to delete the resulting pointer.

clone() [2/2]

template<class Interface >

virtual Interface * Dune::Functions::PolymorphicType< Interface >::clone ( void *  buffer ) const

pure virtual

Clones the object into buffer.

clone(buffer) needs to be redefined by an implementation class, with the return type covariantly adapted. This will return a copy of this created in the given buffer using placement-new with copy construction. You must not delete the returned pointer since it points to the given buffer (however with the proper type instead of void).

move()

template<class Interface >

virtual Interface * Dune::Functions::PolymorphicType< Interface >::move ( void *  buffer )

pure virtual

Move object into buffer.

move(buffer) needs to be redefined by an implementation class, with the return type covariantly adapted. This will return a copy of this created in the given buffer using placement-new with move construction. You must not delete the returned pointer since it points to the given buffer (however with the proper type instead of void).
