Detailed Description

Interface for containers of IThings.

A container, derived from IThing, contains a set of IThings.

This interface provides methods to add, remove and erase an IThing.

In addition, one can search for IThings via their names (as defined by the implementation) or unique integer IDs. A container holds a small granularity callback utility so that other methods can be invoked whenever an IThing is added, removed or erased.

Member Function Documentation

◆ add()

virtual IThing* itasca::IContainer::add	(	IThing *	t,
		quint64	id = `0`
	)

pure virtual

Add the IThing t to the container. A pointer to t is returned. Any method or Signal2 attached to the Signal2 returned by getAddedSignal() will be executed when add() is invoked.

Parameters

t	Pointer to an IThing that will be added to the container. If the container is value based, a copy of t is placed in the container, and the return value is not the same as the argument.

◆ atEnd()

virtual bool itasca::IContainer::atEnd ( IOpaqueIterator * i ) const

pure virtual

Return true if at the end of the container, false otherwise.

Parameters

i	Pointer to IOpaqueIterator.

◆ clear()

virtual void itasca::IContainer::clear ( )

pure virtual

Delete each IThing held in the container. Note that remove() is not invoked. Will execute getRemovedSignal() with a null pointer if there is anything in the container.

◆ copy()

virtual bool itasca::IContainer::copy	(	IOpaqueIterator *	iSrc,
		IOpaqueIterator *	iDst
	)		const

pure virtual

Copy the IOpaqueIterator iSrc to iDst. Returns true if this is successful.

Parameters

iSrc	Pointer to IOpaqueIterator that is the source to be copied.
iDst	Pointer to IOpaqueIterator that is the destination of the copy.

◆ doSilentRemove()

virtual IThing* itasca::IContainer::doSilentRemove ( IThing * t )

pure virtual

Silently remove t. This means that no events are called. DO NOT USE THIS UNLESS YOU KNOW THAT IT IS NECESSARY!!

◆ erase()

virtual void itasca::IContainer::erase ( IThing * t )

pure virtual

Erase the IThing t from the container. This invokes the remove() function and subsequently deletes t. Any method or Signal2 attached to the Signal2 returned by getRemovedSignal() will be executed when erase() is invoked.

Parameters

t	Pointer to an IThing that will be erased from the container.

◆ findWithID() [1/2]

virtual IThing* itasca::IContainer::findWithID ( quint64 id )

pure virtual

Returns the IThing pointer to the IThing with the unique integer ID id. Returns 0 if not found.

Parameters

id	Unique integer ID corresponding to the IThing to be found.

◆ findWithID() [2/2]

virtual const IThing* itasca::IContainer::findWithID ( quint64 id ) const

pure virtual

Returns the const IThing pointer to the IThing with the unique integer ID id. Returns 0 if not found.

Parameters

id	Unique integer ID corresponding to the IThing to be found.

◆ findWithName() [1/2]

virtual IThing* itasca::IContainer::findWithName ( const QString & s )

pure virtual

Returns the IThing pointer to the IThing with the name s. The exact meaning of the QString s is defined by the container and the implementing class. Returns 0 if no match is found.

Parameters

s	QString name of the IThing to be found.
cs	Qt CaseSensitivity object to specify case sensitivity when searching for the IThing with name s.

◆ findWithName() [2/2]

virtual const IThing* itasca::IContainer::findWithName ( const QString & s ) const

pure virtual

Returns the const IThing pointer to the IThing with the name s. The exact meaning of the QString s is defined by the container and the implementing class. Returns 0 if no match is found.

Parameters

s	QString name of the IThing to be found.
cs	Qt CaseSensitivity object to specify case sensitivity when searching for the IThing with name s.

◆ get() [1/2]

virtual IThing* itasca::IContainer::get ( IOpaqueIterator * i )

pure virtual

Return a pointer to the IThing the iterator i refers to.

Parameters

i	Pointer to IOpaqueIterator.

◆ get() [2/2]

virtual const IThing* itasca::IContainer::get ( IOpaqueIterator * i ) const

pure virtual

Return a const pointer to the IThing the iterator i refers to.

Parameters

i	Pointer to IOpaqueIterator.

◆ getAddedSignal()

virtual signal_type* itasca::IContainer::getAddedSignal ( ) const

pure virtual

Returns the small granularity callback Signal2 object (templatized with IThing * and IContainer * arguments) held in the container to which methods or Signal2 objects are attached that will be executed whenever an IThing is added to the container via the add() function. If the first argument (const IThing *) is null, that indicates that the list has just been restored and that ALL elements of the list have effectively been added.

◆ getDestroySignal()

virtual signal_type* itasca::IContainer::getDestroySignal ( ) const

pure virtual

Returns the small granularity callback Signal2 object (templatized with IContainer arguments) held in the container to which methods or Signal2 objects are attached that will be executed just before the container itself is destroyed, allowing objects that depend on it (and hold iterators to it) to clear themselves.

◆ getNextID()

virtual quint64 itasca::IContainer::getNextID ( ) const

pure virtual

Returns an ID one larger than the largest ID of any IThing currently in the container. This ID will be assigned automatically to the next added IThing, if it does not have an ID already.

◆ getRemovedSignal()

virtual signal_type* itasca::IContainer::getRemovedSignal ( ) const

pure virtual

Returns the small granularity callback Signal2 object (templatized with IThing * and IContainer * arguments) held in the container to which methods or Signal2 objects are attached that will be executed whenever an IThing is removed or erased from the container via the remove() or erase() functions. If the first argument (const IThing *) is null, that indicates that the list is about to be cleared of ALL elements.

◆ increment()

virtual bool itasca::IContainer::increment ( IOpaqueIterator * i ) const

pure virtual

Increments the iterator if possible. Returns true if the iterator is incremented (e.g., if there is a next IThing in the container) else false.

Parameters

i	Pointer to IOpaqueIterator.

◆ release()

virtual void itasca::IContainer::release ( IOpaqueIterator * i ) const

pure virtual

Release a previously acquired IOpaqueIterator.

Parameters

i	Pointer to IOpaqueIterator.

◆ remove()

virtual IThing* itasca::IContainer::remove ( IThing * t )

pure virtual

Remove the IThing t from the container. A pointer to t is returned. Any method or Signal2 attached to the Signal2 returned by getRemovedSignal() will be executed when remove() is invoked.

Parameters

t	Pointer to an IThing that will be removed from the container. This function is not allowed on a value based container, and will automatically trigger an exception.
