Reference-counted pointer class and non-member templated function implementations.
Smart reference counting pointer class for automatic garbage collection.
Ptr< T > ptr() const
Get a safer wrapper raw C++ pointer to the underlying object.
T * get() const
Get the raw C++ pointer to the underlying object.
bool nonnull(const boost::shared_ptr< T > &p)
Returns true if p.get()!=NULL.
TEUCHOS_DEPRECATED RCP< T > rcp(T *p, Dealloc_T dealloc, bool owns_mem)
Deprecated.
