Detailed Description

template<class RawAllocator, class Mutex>
class wpi::memory::thread_safe_allocator< RawAllocator, Mutex >

An alias template for allocator_storage using the direct_storage policy with a mutex.

It has a similar effect as allocator_adapter but performs synchronization. The Mutex will default to std::mutex if threading is supported, otherwise there is no default.

Returns:

A new thread_safe_allocator object created by forwarding to the constructor, specifying a certain mutex type.

Requires:

It requires threading support from the implementation.
