Detailed Description

template<typename T>
class regina::StoreManagedPtr< T >

An NProperty storage policy indicating that the property should be held by pointer and that the property wrapper will also take responsibility for memory management.

The property assignment and query routines will also use pointers; in particular the query routines will return a constant pointer. When the held value is changed or the NProperty wrapper is destroyed, any currently held value will be destroyed automatically.

See the NProperty class notes for details.

Python:

Not present.
