Collaboration diagram for Allocators:

## Classes

struct | __gnu_cxx::__alloc_traits< _Alloc >
| Uniform interface to C++98 and C++0x allocators. More...
class | __gnu_cxx::__mt_alloc< _Tp, _Poolp >
| This is a fixed size (power of 2) allocator which - when compiled with thread support - will maintain one freelist per size per thread plus a global one. Steps are taken to limit the per thread freelist sizes (by returning excess back to the global list).Further details: http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch32.html. More...
class | __gnu_cxx::__pool_alloc< _Tp >
| Allocator using a memory pool with a single lock. More...
class | __gnu_cxx::_ExtPtr_allocator< _Tp >
| An example allocator which uses a non-standard pointer type.This allocator specifies that containers use a 'relative pointer' as it's pointer type. (See ext/pointer.h) Memory allocation in this example is still performed using std::allocator. More...
class | __gnu_cxx::array_allocator< _Tp, _Array >
| An allocator that uses previously allocated memory. This memory can be externally, globally, or otherwise allocated. More...
class | __gnu_cxx::bitmap_allocator< _Tp >
| Bitmap Allocator, primary template. More...
class | __gnu_cxx::debug_allocator< _Alloc >
| A meta-allocator with debugging bits, as per [20.4].This is precisely the allocator defined in the C++ Standard. More...
class | __gnu_cxx::malloc_allocator< _Tp >
| An allocator that uses malloc.This is precisely the allocator defined in the C++ Standard. More...
class | __gnu_cxx::new_allocator< _Tp >
| An allocator that uses global new, as per [20.4].This is precisely the allocator defined in the C++ Standard. More...
class | __gnu_cxx::throw_allocator_base< _Tp, _Cond >
| Allocator class with logging and exception generation control. Intended to be used as an allocator_type in templatized code.Note: Deallocate not allowed to throw. More...
class | std::allocator< void >
| allocator<void> specialization. More...
struct | std::allocator_traits< _Alloc >
| Uniform interface to all allocator types. More...
struct | uses_allocator< typename, typename >
| Declare uses_allocator so it can be specialized in <queue> etc. More...

## Detailed Description

Classes encapsulating memory operations.

## Typedef Documentation

template<typename _Tp >

using std::__allocator_base = typedef __gnu_cxx::new_allocator<_Tp>

An alias to the base class for std::allocator.Used to set the std::allocator base class to __gnu_cxx::new_allocator.

Template Parameters

  _Tp | Type of allocated object.
