Detailed Description

create and manipulate ordered lists of objects

vtkCollection is a general object for creating and manipulating lists of objects. The lists are ordered and allow duplicate entries. vtkCollection also serves as a base class for lists of specific types of objects.

virtual vtkTypeBool vtkCollection::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkActor2DCollection, vtkAssemblyPath, vtkPropCollection, vtkActorCollection, vtkLightCollection, vtkRenderPassCollection, vtkAssemblyPaths, vtkProp3DCollection, vtkObjectFactoryCollection, vtkTextPropertyCollection, vtkOverrideInformationCollection, vtkPlaneCollection, vtkMapperCollection, vtkVolumeCollection, vtkDataArrayCollection, vtkIdListCollection, vtkDataObjectCollection, vtkPolyDataCollection, vtkTransformCollection, vtkCullerCollection, vtkRendererCollection, vtkRenderWindowCollection, vtkViewNodeCollection, vtkImageSliceCollection, vtkImplicitFunctionCollection, vtkImageReader2Collection, vtkDataSetCollection, vtkStructuredPointsCollection, and vtkSocketCollection.

void vtkCollection::PrintSelf	(	ostream &	os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

Reimplemented in vtkAssemblyPath, vtkActorCollection, vtkLightCollection, vtkRenderPassCollection, vtkProp3DCollection, vtkTextPropertyCollection, vtkMapperCollection, vtkVolumeCollection, vtkPolyDataCollection, vtkCullerCollection, vtkRendererCollection, vtkRenderWindowCollection, vtkViewNodeCollection, vtkImageReader2Collection, vtkStructuredPointsCollection, and vtkSocketCollection.

static vtkCollection* vtkCollection::New ( )

static

Construct with empty list.

void vtkCollection::AddItem ( vtkObject * )

Add an object to the bottom of the list.

Does not prevent duplicate entries.

void vtkCollection::InsertItem	(	int	i,
		vtkObject *
	)

Insert item into the list after the i'th item.

Does not prevent duplicate entries. If i < 0 the item is placed at the top of the list.

void vtkCollection::ReplaceItem	(	int	i,
		vtkObject *
	)

Replace the i'th item in the collection with another item.

void vtkCollection::RemoveItem ( int i )

Remove the i'th item in the list.

Be careful if using this function during traversal of the list using GetNextItemAsObject (or GetNextItem in derived class). The list WILL be shortened if a valid index is given! If this->Current is equal to the element being removed, have it point to then next element in the list.

void vtkCollection::RemoveItem ( vtkObject * )

Remove an object from the list.

Removes the first object found, not all occurrences. If no object found, list is unaffected. See warning in description of RemoveItem(int).

void vtkCollection::RemoveAllItems ( )

Remove all objects from the list.

int vtkCollection::IsItemPresent ( vtkObject * a )

Search for an object and return location in list.

If the return value is 0, the object was not found. If the object was found, the location is the return value-1.

int vtkCollection::GetNumberOfItems ( )

inline

Return the number of objects in the list.

Definition at line 109 of file vtkCollection.h.

void vtkCollection::InitTraversal ( )

inline

Initialize the traversal of the collection.

This means the data pointer is set at the beginning of the list.

Definition at line 115 of file vtkCollection.h.

void vtkCollection::InitTraversal ( vtkCollectionSimpleIterator & cookie )

inline

A reentrant safe way to iterate through a collection.

Just pass the same cookie value around each time

Definition at line 121 of file vtkCollection.h.

vtkObject * vtkCollection::GetNextItemAsObject ( )

inline

Get the next item in the collection.

nullptr is returned if the collection is exhausted.

Definition at line 177 of file vtkCollection.h.

vtkObject* vtkCollection::GetItemAsObject ( int i )

Get the i'th item in the collection.

nullptr is returned if i is out of range

vtkObject * vtkCollection::GetNextItemAsObject ( vtkCollectionSimpleIterator & cookie )

inline

A reentrant safe way to get the next object as a collection.

Just pass the same cookie back and forth.

Definition at line 192 of file vtkCollection.h.

vtkCollectionIterator* vtkCollection::NewIterator ( )

Get an iterator to traverse the objects in this collection.

void vtkCollection::Register ( vtkObjectBase * o )

overridevirtual

Participate in garbage collection.

Reimplemented from vtkObjectBase.

void vtkCollection::UnRegister ( vtkObjectBase * o )

overridevirtual

Participate in garbage collection.

Reimplemented from vtkObjectBase.

virtual void vtkCollection::RemoveElement	(	vtkCollectionElement *	element,

virtual void vtkCollection::DeleteElement ( vtkCollectionElement * )
