XMLDataContainer (Oracle Fusion Middleware Java API Reference for Oracle Extension SDK Reference)

The XMLDataContainer is the Node wrapper for a Folder-implementing JavaBean that can be persisted to XML using the XML marshalling framework in oracle.ide.marshal.xml.

XMLDataContainer wraps objects that can contain children. In order to interact with XMLDataContainer, wrapped objects must implement Folder.

All methods to the XMLDataContainer's Element and Folder methods are forwarded to the wrapped Folder object.

If the wrapped object is not an instance of Folder, then an IllegalStateException will be thrown every time an operation that requires the children list is called.

Method Summary
`boolean`	`add(Element element)` Appends a child `Element` to the end of the `Folder`.
`boolean`	`add(Element element, boolean notify)`
`boolean`	`canAdd(Element element)` Other classes can call this method to determine whether the given `Element` can be added to the `Folder`.
`boolean`	`canRemove(Element element)` Other classes can call this method to determine whether the specified `Element` can be removed from this `Folder`.
`boolean`	`containsChild(Element child)` Returns `true` if the folder contains the specified child `Element`; returns `false` otherwise.
`protected Folder`	`getDataFolder()` Retrieves the `Folder` object associated with this `XMLDataContainer` instance.
`boolean`	`mayHaveChildren()` This method is part of the `Element` interface to provide a convenient way of determining whether an object may have children without having to test the object's type with the `instanceof` operator or having to downcast to a more specific type.
`boolean`	`remove(Element element)` Removes the specified child `Element`.
`boolean`	`remove(Element element, boolean notify)`
`void`	`removeAll()` Removes all children from the folder.
`void`	`removeAll(boolean notify)`
`int`	`size()` Returns the current number of children in the folder.

Method Detail

mayHaveChildren

public boolean mayHaveChildren()

Description copied from interface: Element

This method is part of the Element interface to provide a convenient way of determining whether an object may have children without having to test the object's type with the instanceof operator or having to downcast to a more specific type.

An implementation of Element that represents a leaf in a tree structure should return false from this method. An implementation of Element that could represent a non-leaf in a tree structure should return true from this method, even if it does not currently contain any children.

Specified by:: mayHaveChildren in interface Element
Overrides:: mayHaveChildren in class XMLDataNode

Returns:: true if this Element may contain child Elements.
