#4493: shared_array lacks get_deleter method
 Reporter: Matthew Carter <r_q_einstein-boostbugs@…> | Owner: no-maintainer

Milestone: Boost 1.44.0 | Component: array
  Version: Boost 1.44.0 | Severity: Problem
 Keywords: |
 shared_ptr has a get_deleter() method, which is very useful.
 shared_array does not have a get_deleter() method.

 Since the deleter for a shared_array is passed to the constructor by
 value, there is no straightforward way* for the caller to get a pointer or
 reference to it. If the caller needs access to the deleter object's state
 or methods, which is entirely reasonable, the caller has no way to get it.

 A get_deleter() method should be added to shared_array to meet this
 requirement and for consistency with the shared_ptr class.

 *True, the caller can pass the deleter wrapped in a container object that
 holds a reference to the deleter, but that's a contortion that should not
 be necessary.
