Detailed Description

The classes provided here support conventional modern C++ library design principles for component software to achieve binary compatibility across shared library boundaries and future extensibility.

The design provides access through interfaces, which are abstract base classes with pure virtual member functions.

Interfaces derived from mi::base::IInterface refer to reference-counted dynamic resources that need to be released. To avoid manual reference counting, you can use the provided handle class mi::base::Handle, which is a smart-pointer implementation with automatic reference counting. You can also use other handle class implementations, e.g., std::tr1::shared_ptr<T> (or boost::shared_ptr<T>).

^◆ cast_to_major() [1/2]

template<typename MAJOR , typename MINOR>

MAJOR * mi::base::Interface_merger<MAJOR, MINOR>::cast_to_major ( )

inline

Returns a pointer to the MAJOR base class.

Note that mi::base::IInterface is an ambiguous base class. Often you just need a pointer to mi::base::IInterface but do not really care to which base class it actually points to. This method is intended to be used in these cases. It returns the pointer to the MAJOR base class, which can then be statically casted to mi::base::IInterface (unless Interface_merger is nested).

Note: The name cast_to_major() of this method emphasizes that it behaves similar to a static cast, in particular, it does not increase the reference count.

^◆ cast_to_major() [2/2]

template<typename MAJOR , typename MINOR>

const MAJOR * mi::base::Interface_merger<MAJOR, MINOR>::cast_to_major ( ) const

inline

Returns a pointer to the MAJOR base class.

Note that mi::base::IInterface is an ambiguous base class. Often you just need a pointer to mi::base::IInterface but do not really care to which base class it actually points to. This method is intended to be used in these cases. It returns the pointer to the MAJOR base class, which can then be statically casted to mi::base::IInterface (unless Interface_merger is nested).

Note: The name cast_to_major() of this method emphasizes that it behaves similar to a static cast, in particular, it does not increase the reference count.

^◆ get_interface() [1/15]

template<class T>

T * mi::base::IInterface::get_interface ( )

inline

Acquires a mutable interface from another.

If this interface supports the interface T, then the method returns a non-NULL pointer to the interface T. Otherwise, the method returns NULL.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to apply static_cast to the returned pointer, since the return type already is a pointer to the type T specified as template parameter.

Template Parameters

T	The requested interface type.

template<typename MAJOR , typename MINOR>

template<class T>

T * mi::base::Interface_merger<MAJOR, MINOR>::get_interface ( )

inline

Returns a new handle for a possibly different interface type, similar to a dynamic cast, but not necessarily restricted to derived interfaces, but also for otherwise related interfaces.

Returns a handle with an invalid interface if the requested interface type is not supported by the underlying interface implementation or if this interface is itself already invalid.

^◆ get_interface() [4/15]

template<class T>

const T * mi::base::IInterface::get_interface ( ) const

inline

Acquires a const interface from another.

If this interface supports the interface T, then the method returns a non-NULL const pointer to the interface T. Otherwise, the method returns NULL.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to apply static_cast to the returned pointer, since the return type already is a const pointer to the type T specified as template parameter.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

^◆ get_interface() [8/15]

template<class I>

virtual IInterface * mi::base::Interface_implement_singleton::get_interface ( const Uuid & interface_id )

inlinevirtual

^◆ get_interface() [11/15]

template<class I1 , class I2>

virtual const IInterface * mi::base::Interface_implement_2<I1, I2>::get_interface ( const Uuid & interface_id ) const

inlinevirtual

Acquires a const interface.

If this interface is derived from or is the interface with the passed interface_id, then return a non-NULL const mi::base::IInterface* that can be casted via static_cast to an interface pointer of the interface type corresponding to the passed interface_id. Otherwise return NULL.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

template<class I>

virtual const IInterface * mi::base::Interface_implement_singleton::get_interface ( const Uuid & interface_id ) const

Acquires a const interface.

If this interface is derived from or is the interface with the passed interface_id, then return a non-NULL const mi::base::IInterface* that can be casted via static_cast to an interface pointer of the interface type corresponding to the passed interface_id. Otherwise return NULL.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

^◆ get_interface() [14/15]

virtual const IInterface * mi::base::IInterface::get_interface ( const Uuid & interface_id ) const

pure virtual

Acquires a const interface from another.

If this interface supports the interface with the passed interface_id, then the method returns a non-NULL const mi::base::IInterface* that can be casted via static_cast to an interface pointer of the interface type corresponding to the passed interface_id. Otherwise, the method returns NULL.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

Parameters

interface_id Interface ID of the interface to acquire.

Implemented in mi::base::Interface_implement_singleton<IAllocator>.

If this interface supports the interface with the passed interface_id, then the methods returns a non-NULL mi::base::IInterface* that can be casted via static_cast to an interface pointer of the interface type corresponding to the passed interface_id. Otherwise, the method returns NULL.

In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.

Parameters

^◆ Handle() [5/7]

template<class Interface>

mi::base::Handle<Interface>::Handle ( Interface * ptr )

inlineexplicit

Constructor from interface pointer, takes ownership of interface.

The constructor does not increment the reference count of ptr assuming it is already set properly, e.g., by a corresponding get_interface() call. It therefore takes over the ownership of the interface pointer.

^◆ Handle() [6/7]

template<class Interface>

mi::base::Handle<Interface>::Handle	(	Interface *	ptr,
		Dup_interface
	)

inline

Constructor from interface pointer, does not take ownership of interface but duplicates it.

The constructor increments the reference count of ptr so that it does not influence the interface when it decrements the reference count later on. You can use this constructor for example to hold interfaces that are passed into functions as parameters because by convention they are owned by the function caller. You can pass the constant DUP_INTERFACE as the second argument.
