Allocator Concept

The Allocator Concept for allocators in Intel Threading Building Blocks is similar to the allocator requirements in Table 32 of the ISO C++ standard, but with further guarantees required by the ISO C++ standard (Section 20.1.5, paragraph 4) for use with ISO C++ containers. Table 6-1 summarizes the Allocator Concept. Here, A and B represent instances of the allocator class.

Pseudosignature

Semantics

typedef T* A::pointer

Pointer to T

typedef const T* A::const_pointer

Pointer to const T

typedef T& A::reference

Reference to T

typedef const T& A::const_reference

Reference to const T

typedef T A::value_type

Type of value to be allocated

typedef size_t A::size_type

Type for representing number of values

typedef ptrdiff_t A::difference_type

Type for representing pointer difference

template<typename U> struct rebind {
 typedef A<U> A::other;
};

Rebind to a different type U

A() throw()

Default constructor

A( const A& ) throw()
