Detailed Description

template<class T>
class GiNaC::ptr< T >

Class of (intrusively) reference-counted pointers that support copy-on-write semantics.

Requirements for T: must support the refcounted interface (usually by being derived from refcounted) T* T::duplicate() member function (only if makewriteable() is used)
