Detailed Description

template<typename Alloc>
class bmb::AllocatorTraits< Alloc >

Unifined interface for allocators.

All callers to any allocator should do it throw this class-proxy. It predefines some default methods in case a allocator dosn't do it. Otherwise it calls the allocator's method.

Member Function Documentation

allocate()

template<typename Alloc >

template<typename T >

static T * bmb::AllocatorTraits< Alloc >::allocate ( Alloc &  alloc, size_t  n  )

inlinestatic

Allocates given number of objects using allocator.

Parameters

alloc	Allocator to use for allocation
n	Number of objects to allocate

Returns

Pointer to the allocated memory

Exceptions

Same	as alloc.allocate(...)

construct()

template<typename Alloc >

template<typename T , typename... Args>

static void bmb::AllocatorTraits< Alloc >::construct ( Alloc &  alloc, T *  ptr, Args &&...  args  )

inlinestatic

Forwards given arguments to allocator's construct method if present. Otherwise uses placement new.

Parameters

alloc	Allocator to use in construction
ptr	Pointer to raw memory where to construct
args...	Arguments to pass in constructor

Exceptions

Same	as alloc.construct(...) if present. Otherwise same specification as new

deallocate()

template<typename Alloc >

template<typename T >

static void bmb::AllocatorTraits< Alloc >::deallocate ( Alloc &  alloc, T *  ptr, size_t  n  )

inlinestatic

Deallocates memory under ptr through allocator.

Parameters

alloc	Allocator to use in deallocation
ptr	Pointer to the previously allocated memory
n	Number of objects to deallocate

Exceptions

Same	specification as alloc.deallocate()

destroy()

template<typename Alloc >

template<typename T >

static void bmb::AllocatorTraits< Alloc >::destroy ( Alloc &  alloc, T *  ptr  )

inlinestatic

Destroys object throgh alloctor if destroy method is present. Otherwise calls ~T()

Parameters

alloc	Allocator to use in destruction
ptr	Pointer to object to destroy

Exceptions

If	allocator has method destroy - throws the same. Otherwise doesn't throw(in assumption object destructor doesn't throw)
