Folder
contract.
WARNING: it is suggested that you verify the types of each element in the returned list, as there is no guarantee that all elements share the same type. Usually all of them are of type @{link Element} but there can be a few elements of type @{link Reference} as well, this happens when a

public void setListOfChildren(java.util.List<?> list)
Folder
contract. Sets the child list of the DataFolder
instance to match the specified List
. Only objects in the List
that can be cast to Element
are added. The implementation uses the DefaultFolder.add(Element)
method to add the child to the list, so that subclass implementations can override DefaultFolder.add(Element)
without having to also override this method.public boolean mayHaveChildren()
Element
interface. This implementation always returns true
.mayHaveChildren
in interface Element
mayHaveChildren
in class Node

may contain child Element

public java.util.Iterator<Element> getChildren()
Element
interface. This implementation returns an Iterator
over the current list of children.getChildren
in interface Element
getChildren
in class Node
Iterator
over any child Element
s contained by this Element
. If there are no children, null
is returned.Element.getChildren()
public boolean canAdd(Element element)
Folder
interface. The default implementation returns true
if and only if the specified Element
is not null

in interface Folder

that is about to be added to this Folder
.true
if and only if the specified Element
is not null
.Folder.canAdd(Element)
public boolean add(Element element)
Folder
interface. The specified Element
is added to the end of the child list. However, if the Element
is null
, this method does nothing.
No notification is fired by this method.

Folder.add(oracle.ide.model.Element)
public boolean canRemove(Element element)

interface. The default implementation returns true

is not null

that is about to be removed from this Folder
.true
if and only if the specified Element
is not null
.Folder.canRemove(Element)
public boolean remove(Element element)
Folder
interface. The specified Element
is removed from the child list. However, if the Element
is null
, this method does nothing. If the Element
occurs more than once in the child list, then only the first instance is removed.
No notification is fired by this method.

public boolean add(java.util.Collection childElements, boolean notify)
Collection
of Element
objects to the child list for the container. Each Element
is added with the add(Element, boolean)
method. If an Object
in the Collection
is not an Element
or if an Element
cannot be added to the container, then it is skipped and false
is returned; the other Element
objects in the Collection
will still be added, however.protected void resetSubDirtyableOwners(java.util.List children)
SubDirtyable
element. When a sub-dirtyable element is made dirty it actually makes its owner dirty.protected void setSubDirtyableOwner(Element element, Dirtyable owner)
