Component bslma_allocator

Description:

This component provides a protocol (pure abstract interface) class, bslma::ManagedAllocator, which extends the base-level protocol class, bslma::Allocator, providing the ability to release all memory currently allocated through the protocol back to the memory supplier of the derived concrete allocator object.

   ,-----------------------.
  ( bslma::ManagedAllocator )
   `-----------------------'
               |       release
               V
       ,----------------.
      ( bslma::Allocator )
       `----------------'
                       allocate
                       deallocate

Usage:

The bslma::ManagedAllocator protocol class serves as a useful internal interface for documentation purpose and could be used as a parameter to low-level helper functions for some implementations. We have yet to find a suitable real-world example and when one becomes available, it will be added.
