public class UIXTree
extends UIXHierarchy
implements javax.faces.component.NamingContainer

Apache Trinidad tree components are used to display hierarchical data. For example, if we have a personnel organization chart depicting all the direct reports under each employee, we could use a tree component to display this chart. While each element (employee) in the hierarchy may have any number of child elements, each element can only have one parent element.

The Apache Trinidad tree components use a model to access the data in the underlying hierarchy. The specific model class is org.apache.myfaces.trinidad.model.TreeModel. You may find the org.apache.myfaces.trinidad.model.ChildPropertyTreeModel class useful when constructing a TreeModel.
The tree components use a stamping strategy similar to the Trinidad Table component. Child components are used to display the data for each element in the tree. Each child component is not recreated per element; instead, each child is repeatedly rendered (stamped) once per element. Because of this stamping behavior, only certain types of components are supported as children. Supported components include all components with no behavior and most components that implement the EditableValueHolder or ActionSource interfaces. Each time a child component is stamped, the data for the current element is copied into an EL reachable property. The name of this property is defined by the var property on the tree component. Once the tree has completed rendering, this property is removed (or reverted back to its previous value).
When the user expands or collapses a subtree the tree generates a DisclosureEvent. This event has an isExpanded method that returns whether the user wants to expand or collapse the subtree of a particular element. That particular element is made current on the Tree before the event is delivered.
The Trinidad tree components use an instance of the org.apache.myfaces.trinidad.model.RowKeySet class to keep track of which elements are expanded. This instance is stored as the "expandedRowKeys" attribute on the component. You may use this instance to programmatically control the expand/collapse state of an element in the hierarchy.

Events:

Type Phases Description
org.apache.myfaces.trinidad.event.RowDisclosureEvent Apply
Request
Values
Invoke
Application
The expansion event is generated for a table when the detail facet of a row is expanded or collapsed. For tree or a treeTable, the expansion event is generated when tree nodes are expanded or collapsed.
org.apache.myfaces.trinidad.event.SelectionEvent Apply
Request
Values
Invoke
Application
The selection event is delivered when the table selection changes.
org.apache.myfaces.trinidad.event.FocusEvent Apply
Request
Values
Invoke
Application
Event delivered when user clicks to focus on (or zoom into) a particular element's subtree of children. The TreeTable responds to this event by modifying the "focusPath" property appropriately. Subsequently, any registered FocusListener instances are called.
org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke
Application
Apply
Request
Values
Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

postCreateCollectionModel

protected void postCreateCollectionModel(CollectionModel model)
Description copied from class: UIXCollection
Hook called with the result of createCollectionModel. Subclasses can use this method to perform initialization after the CollectionModel is fully initialized. Subclassers should call super before accessing any component state to ensure that superclass initialization has been performed.

UIXCollection.processComponent(javax.faces.context.FacesContext, javax.faces.component.UIComponent, javax.faces.event.PhaseId) may be called repeatedly for the same child if that child is being stamped.

Specified by:

Subclasses should override this method if they wish to change the way in which the non-stamped children are visited. If they wish to change the wash the the stamped children are visited, they should override visitData instead.

Overrides:

Parameters:
visitContext - the VisitContext for this visit
callback - the VisitCallback instance
Returns:
true if all of the children to visit have been visited

Parameters:
visitContext - The visiting context
callback - The visit callback
Returns:
true if the visiting should stop
See Also:

getNodeStamp

public final javax.faces.component.UIComponent getNodeStamp()

isImmediate

public final boolean isImmediate()
Gets whether or not data validation - client-side or server-side - should take place when events are generated by this component. When immediate is true, the default ActionListener provided by the JavaServer Faces implementation should be executed during Apply Request Values phase of the request processing lifecycle, rather than waiting until the Invoke Application phase.

Returns:
the new immediate value

setImmediate

public final void setImmediate(boolean immediate)
Sets whether or not data validation - client-side or server-side - should take place when events are generated by this component. When immediate is true, the default ActionListener provided by the JavaServer Faces implementation should be executed during Apply Request Values phase of the request processing lifecycle, rather than waiting until the Invoke Application phase.

Returns:
the new rowDisclosureListener value

setRowDisclosureListener

Sets a method reference to an ExpansionListener

Parameters:
rowDisclosureListener - the new rowDisclosureListener value

getDisclosedRowKeys

public final RowKeySet getDisclosedRowKeys()
Gets the set of disclosed rows for this component. Each entry in the set is a rowKey.

Returns:
the new disclosedRowKeys value

setDisclosedRowKeys

public final void setDisclosedRowKeys(RowKeySet disclosedRowKeys)
Sets the set of disclosed rows for this component. Each entry in the set is a rowKey.

Parameters:

getSelectionListener

public final javax.el.MethodExpression getSelectionListener()
Gets a method reference to a selection listener

Returns:
the new selectionListener value

setSelectionListener

public final void setSelectionListener(javax.el.MethodExpression selectionListener)
Sets a method reference to a selection listener

Parameters:
selectionListener - the new selectionListener value

getVarStatus

public final String getVarStatus()
Gets Name of the EL variable used to reference the varStatus information. Once this component has completed rendering, this variable is removed (or reverted back to its previous value). The VarStatus provides contextual information about the state of the component to EL expressions. For components that iterate, varStatus also provides loop counter information. Please see the this component's documentation for the specific properties on the varStatus. The common properties on varStatus include:
  • "model" - returns the CollectionModel for this component
  • "index" - returns the zero based row index
  • "hierarchicalIndex" - returns an array containing the row indices of heirarchy of the currrent row, for e.g. [0,1,2] Please use this attribute with caution since it requires moving currency to calculate the row index for each parent collection in the tree hierarchy.
  • "hierarchicalLabel" - returns a string label representing the hierarchy of that row, for e.g. 1.1, 1.1.1. It should be noted that the labels are 1 based vs 0 based for rowIndex. Please use this attribute with caution since it requires moving currency to calculate the row index for each parent collection in the tree hierarchy.

Specified by:
getVarStatus in class UIXCollection
Returns:
the new varStatus value
See Also:
UIXCollection.createVarStatusMap()

setVarStatus

public final void setVarStatus(String varStatus)
Sets Name of the EL variable used to reference the varStatus information. Once this component has completed rendering, this variable is removed (or reverted back to its previous value).
