GenericNode

protected GenericNode(RescatContext rescatContext,
                      Element parent)

Method Detail

getParent

public final Element getParent()

getRescatContext

public RescatContext getRescatContext()

getChildren

public java.util.Iterator<Element> getChildren()

Description copied from interface: Element

This method is part of the Element interface to provide a convenient way of getting an Iterator over any contained child Elements 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 null from this method. An implementation of Element that could represent a non-leaf in a tree structure should return either an Iterator over the child Elements or null if there are no children.

Specified by:

getChildren in interface Element

Overrides:

getChildren in class Node

Returns:

an Iterator over any child Elements contained by this Element. If there are no children, null is returned.

getChildrenImpl

protected java.util.List<E> getChildrenImpl()

Override this method (and not getChildren()) to cache the children.

setFilterControl

public final void setFilterControl(oracle.adf.rc.core.FilterControl filterControl)

getLongLabel

public java.lang.String getLongLabel()

Description copied from class: Node

Displayable interface method. The Node class returns the path name part of the currently set URL. If the currently set URL is null, then this method returns "<null>".

Specified by:

getLongLabel in interface Displayable

Overrides:

getLongLabel in class Node

Returns:

a long descriptive label of the Displayable that can be shown to the user.

getIcon

public javax.swing.Icon getIcon()

Description copied from class: Node

Displayable interface method. The Node class returns a generic icon.

Specified by:

getIcon in interface Displayable

Overrides:

getIcon in class Node

Returns:

the Icon to be displayed for the Displayable.

getIconOverlays

protected javax.swing.Icon getIconOverlays(javax.swing.Icon icon)

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 Node

Returns:

true if this Element may contain child Elements.

whenDelete

public final boolean whenDelete(boolean doit)

whenRename

public final boolean whenRename(java.lang.String newName,
                                boolean doit)

whenRename

protected boolean whenRename(E childNode,
                             java.lang.String newName,
                             boolean doit)

whenDelete

public boolean whenDelete(E childElement,
                          boolean doit)

Delete childElement from this node.

Parameters:

childElement - the element to delete

whenProperties

public boolean whenProperties(Context context,
                              boolean doit)

forceRefresh

public final void forceRefresh()

forceRefreshImpl

protected void forceRefreshImpl()

hook for subclasses to extend the behavior of forceRefresh() such as clearing intermediate caches.

equalsImpl

protected boolean equalsImpl(java.lang.Object other)

setAttributes

protected void setAttributes(E element)

Set the attributes of the specified element to make it read-only and disable Erase from Disk, Delete, Rename. This method may be overridden by subclasses. For example. RepositoryRootNodes should be deleteable

getFullPath

public final java.lang.String getFullPath()

Returns:

the full path to the node. For example: "My Catalogs/catalog1/folder1/folder2"

getPathFrom

public final java.lang.String getPathFrom(java.lang.Class parentType)

Returns:

the path of this node up to a parent of the type specified by parentType (or last GenericNode)

getElementComparator

protected java.util.Comparator<Element> getElementComparator()

Returns the Comparator that should be used for sorting the children of this node.

Returns:

the Comparator that should be used for sorting the children of this node.
