template<typename T>
ScopedPtr class
A smart pointer that deletes the pointee object when going out of scope. This should have a very similar interface to boost scoped_ptr or std unique_ptr so that once C++11 is suported overall compilers we can switch easily. However due to lack of C++11 support, it does not support move semantics.
Public types

Releases the ownership of the pointee
template<typename T>
pointer_type eckit::
| Returns | a pointer to the managed object or null if no object is owned. Should be used with caution, because of issues dealing with raw pointers. However, get makes it possible to explicitly test whether the stored point is NULL. The function never throws. get is typically used when calling functions that require a raw pointer. Note: previously this asserted ptr_ was not null, however this is inconsistent with the standard boost scoped_ptr or std unique_ptr |
