Inheritance diagram for winstd::crypt_hash:

Public Member Functions
virtual	~crypt_hash ()
	Destroys the hash context.

Public Member Functions inherited from winstd::dplhandle< HCRYPTHASH, NULL >
	dplhandle () noexcept
	Initializes a new class instance with the object handle set to INVAL.

	dplhandle (handle_type h) noexcept
	Initializes a new class instance with an already available object handle.

	dplhandle (const dplhandle< handle_type, INVAL > &h)
	Copy constructor.

	dplhandle (dplhandle< handle_type, INVAL > &&h) noexcept
	Move constructor.

dplhandle< handle_type, INVAL > &	operator= (handle_type h) noexcept
	Attaches already available object handle.

dplhandle< handle_type, INVAL > &	operator= (const dplhandle< handle_type, INVAL > &h) noexcept
	Duplicates the object.

dplhandle< handle_type, INVAL > &	operator= (dplhandle< handle_type, INVAL > &&h) noexcept
	Moves the object.

handle_type	duplicate () const
	Duplicates and returns a new object handle.

void	attach_duplicated (handle_type h)
	Duplicates an object handle and sets a new object handle.

Public Member Functions inherited from winstd::handle< T, INVAL >
	handle () noexcept
	Initializes a new class instance with the object handle set to INVAL.

	handle (handle_type h) noexcept
	Initializes a new class instance with an already available object handle.

	handle (handle< handle_type, INVAL > &&h) noexcept
	Move constructor.

handle< handle_type, INVAL > &	operator= (handle_type h) noexcept
	Attaches already available object handle.

handle< handle_type, INVAL > &	operator= (handle< handle_type, INVAL > &&h) noexcept
	Move assignment.

	operator handle_type () const
	Auto-typecasting operator.

handle_type *&	operator* () const
	Returns the object handle value when the object handle is a pointer to a value (class, struct, etc.).

handle_type *	operator& ()
	Returns the object handle reference.

handle_type	operator-> () const
	Provides object handle member access when the object handle is a pointer to a class or struct.

bool	operator! () const
	Tests if the object handle is invalid.

bool	operator< (handle_type h) const
	Is handle less than?

bool	operator<= (handle_type h) const
	Is handle less than or equal to?

bool	operator>= (handle_type h) const
	Is handle greater than or equal to?

bool	operator> (handle_type h) const
	Is handle greater than?

bool	operator!= (handle_type h) const
	Is handle not equal to?

bool	operator== (handle_type h) const
	Is handle equal to?

void	attach (handle_type h) noexcept
	Sets a new object handle for the class.

handle_type	detach ()
	Dismisses the object handle from this class.

void	free ()
	Destroys the object.

Protected Member Functions
void	free_internal () noexcept override
	Destroys the hash context.

handle_type	duplicate_internal (handle_type h) const override
	Duplicates the hash context.

virtual handle_type	duplicate_internal (handle_type h) const=0
	Abstract member function that must be implemented by child classes to do the actual object handle duplication. On failure, it should throw appropriate exception describing the cause, rather than return an invalid handle.

virtual void	free_internal () noexcept=0
	Abstract member function that must be implemented by child classes to do the actual object destruction.

Additional Inherited Members
Public Types inherited from winstd::handle< T, INVAL >
typedef T	handle_type
	Datatype of the object handle this template class handles.

Static Public Attributes inherited from winstd::handle< T, INVAL >
static const T	invalid = INVAL
	Invalid handle value.

Protected Attributes inherited from winstd::handle< T, INVAL >
handle_type	m_h
	Object handle.
