Detailed Description

template<typename T>
struct adobe::ptr_traits< T * >

The ptr_traits class provide basic information and operations associated with a pointer type.

A pointer may be any type used to refer to another, possibly not visible, type.

In the following table, X denotes a Traits class defining types and functions for the pointer type PtrT. The type of the item refered to is T. T may be void or an incomplete type. The argument p is of type PtrT.

expression return type notes complexity
X::element_type T the type of the item refered to compile time
X::pointer_type PtrT if opaque, may be any type used to refer to T compile time
X::const_pointer_type implementation defined type corresponding to PtrT refering to a const T compile time
X::is_array bool true iff T is an array; type may also be convertable to bool compile time
X::delete_ptr(p) void destructs and deallocates item refered to by p; if p is empty, delete_ptr() has no effect implementation defined
X::empty_ptr(p) bool result is true if p refers to nothing (corresponds to NULL); false otherwise constant
