Detailed Description

template<typename T>
class lldb_private::NonNullSharedPtr< T >

A non-nullable shared pointer that always holds a valid object.

NonNullSharedPtr is a smart pointer wrapper around std::shared_ptr that guarantees the pointer is never null.

This class is used for enforcing invariants at the type level and eliminating entire classes of null pointer bugs.

Template Parameters

T	The type of object to manage. Must be default-constructible.
