allocator_base Class

Defines the base class and common functions needed to create a user-defined allocator from a synchronization filter.

template <class Type, class Sync> class allocator_base

Parameters

Parameter	Description
Type	The type of elements allocated by the allocator.
Sync	The synchronization policy for the allocator, which is sync_none Class, sync_per_container Class, sync_per_thread Class, or sync_shared Class.

Constructs an object of type allocator_base.

const_pointer	A type that provides a constant pointer to the type of object managed by the allocator.
const_reference	A type that provides a constant reference to type of object managed by the allocator.
difference_type	A signed integral type that can represent the difference between values of pointers to the type of object managed by the allocator.
pointer	A type that provides a pointer to the type of object managed by the allocator.
reference	A type that provides a reference to the type of object managed by the allocator.
size_type	An unsigned integral type that can represent the length of any sequence that an object of template class allocator_base can allocate.
value_type	A type that is managed by the allocator.

_Charalloc	Allocates storage for an array of type char.
_Chardealloc	Frees storage for the array containing elements of type char.
address	Finds the address of an object whose value is specified.
allocate	Allocates a block of memory large enough to store at least some specified number of elements.
construct	Constructs a specific type of object at a specified address that is initialized with a specified value.
deallocate	Frees a specified number of objects from storage beginning at a specified position.
destroy	Calls an objects destructor without deallocating the memory where the object was stored.
max_size	Returns the number of elements of type Type that could be allocated by an object of class allocator before the free memory is used up.
