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 |
