Method Detail

areChildrenAllowed

public boolean areChildrenAllowed(Object itemId)

Deprecated.

Description copied from interface: Container.Hierarchical

Tests if the Item with given ID can have children.

Specified by:

areChildrenAllowed in interface Container.Hierarchical

Parameters:

itemId - ID of the Item in the container whose child capability is to be tested

Returns:

true if the specified Item exists in the Container and it can have children, false if it's not found from the container or it can't have children.

getChildren

public Collection<?> getChildren(Object itemId)

Deprecated.

Description copied from interface: Container.Hierarchical

Gets the IDs of all Items that are children of the specified Item. The returned collection is unmodifiable.

Specified by:

getChildren in interface Container.Hierarchical

Parameters:

itemId - ID of the Item whose children the caller is interested in

Returns:

An unmodifiable collection containing the IDs of all other Items that are children in the container hierarchy; null if item does not have any children.

getParent

public Object getParent(Object itemId)

Deprecated.

Description copied from interface: Container.Hierarchical

Gets the ID of the parent Item of the specified Item.

Specified by:

getParent in interface Container.Hierarchical

Parameters:

itemId - ID of the Item whose parent the caller wishes to find out.

Returns:

the ID of the parent Item. Will be null if the specified Item is a root element.

hasChildren

public boolean hasChildren(Object itemId)

Deprecated.

Description copied from interface: Container.Hierarchical

Tests if the Item specified with itemId has child Items or if it is a leaf. The Container.Hierarchical.getChildren(Object itemId) method always returns null for leaf Items.

Note that being a leaf does not imply whether or not an Item is allowed to have children.

Specified by:

hasChildren in interface Container.Hierarchical

Parameters:

itemId - ID of the Item to be tested

Returns:

true if the specified Item has children, false if not (is a leaf)

isRoot

public boolean isRoot(Object itemId)

Deprecated.

Description copied from interface: Container.Hierarchical

Tests if the Item specified with itemId is a root Item. The hierarchical container can have more than one root and must have at least one unless it is empty. The Container.Hierarchical.getParent(Object itemId) method always returns null for root Items.

Specified by:

isRoot in interface Container.Hierarchical

Parameters:

itemId - ID of the Item whose root status is to be tested

Returns:

true if the specified Item is a root, false if not

rootItemIds

public Collection<?> rootItemIds()

Deprecated.

Description copied from interface: Container.Hierarchical

Gets the IDs of all Items in the container that don't have a parent. Such items are called root Items. The returned collection is unmodifiable.

Specified by:

rootItemIds in interface Container.Hierarchical

Returns:

An unmodifiable collection containing IDs of all root elements of the container

setChildrenAllowed

public boolean setChildrenAllowed(Object itemId,
                                  boolean areChildrenAllowed)
                           throws UnsupportedOperationException

Deprecated.

Description copied from interface: Container.Hierarchical

Sets the given Item's capability to have children. If the Item identified with itemId already has children and Container.Hierarchical.areChildrenAllowed(Object) is false this method fails and false is returned.

The children must be first explicitly removed with Container.Hierarchical.setParent(Object itemId, Object newParentId)or Container.removeItem(Object itemId).

This operation is optional. If it is not implemented, the method always returns false.

Specified by:

setChildrenAllowed in interface Container.Hierarchical

Parameters:

itemId - ID of the Item in the container whose child capability is to be set

areChildrenAllowed - boolean value specifying if the Item can have children or not

Returns:

true if the operation succeeded, false if not

Throws:

UnsupportedOperationException

setParent

public boolean setParent(Object itemId,
                         Object newParentId)
                  throws UnsupportedOperationException

Deprecated.

Description copied from interface: Container.Hierarchical

Sets the parent of an Item. The new parent item must exist and be able to have children. ( Container.Hierarchical.areChildrenAllowed(Object) == true ). It is also possible to detach a node from the hierarchy (and thus make it root) by setting the parent null.

This operation is optional.

Specified by:

setParent in interface Container.Hierarchical

Parameters:

itemId - ID of the item to be set as the child of the Item identified with newParentId

newParentId - ID of the Item that's to be the new parent of the Item identified with itemId

Returns:

true if the operation succeeded, false if not

Throws:

UnsupportedOperationException
