template <class Type, class Sync> class allocator_base

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.

allocator_base

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.
