Luna::UniquePtr

A smart pointer that wraps one dynamically created object, and deletes the object when the pointer is destructed.

template <typename _Ty, typename _Deleter>
class Luna::UniquePtr

Parameters

• _Ty

  The type of the object to wrap.

• _Deleter

  The object deletion function to use.

Member functions

• constexpr UniquePtr()

  Constructs one null smart pointer.

• constexpr UniquePtr(nullptr_t)

  Constructs one null smart pointer with nullptr_t.

• UniquePtr(pointer p)

  Constructs one smart pointer by wrapping pointer p.

• UniquePtr(pointer p, const deleter_type &d)

  Constructs one smart pointer by wrapping pointer p with custom object deletion function.

• UniquePtr(pointer p, deleter_type &&d)

  Constructs one smart pointer by wrapping pointer p with custom object deletion function.

• pointer get() const

  Gets the underlying native pointer.

• deleter_type & get_deleter()

  Get the object deletion function.

• const deleter_type & get_deleter() const

  Get the object deletion function.

• operator bool() const

  Checks whether this smart pointer is not null.

• add_lvalue_reference< _Ty >::type operator*() const

  Dereferences the native pointer.

• pointer operator->() const

  Accesses members of the instance pointed by the pointer.

• pointer release()

  Sets the native pointer to null, and gets the original pointer.

• void reset(pointer ptr=pointer())

  Sets the native pointer of this smart pointer. If this smart pointer is not null, the original instance pointed by this smart pointer will be deleted.

• void swap(UniquePtr &rhs)

  Swaps native pointers of this smart pointer with the specified smart pointer.

• UniquePtr(UniquePtr &&rhs)

  Constructs one smart pointer by moving native pointer from another smart pointer.

• UniquePtr & operator=(UniquePtr &&rhs)

  Assigns one smart pointer by moving native pointer from another smart pointer. If this smart pointer is not null, the original instance pointed by this smart pointer will be deleted.

• UniquePtr & operator=(nullptr_t)

  Sets one smart pointer to null. If this smart pointer is not null, the original instance pointed by this smart pointer will be deleted.

• bool operator==(const UniquePtr &rhs) const

  Compares two smart pointers for equality. Two smart pointers are equal if their native pointers are equal or both null.

• bool operator!=(const UniquePtr &rhs) const

  Compares two smart pointers for non-equality.
