Class TableTreeContentProvider

java.lang.Object

com.webmethods.caf.faces.bean.PageFlowScopeAdapter

com.webmethods.caf.faces.data.tree.object.TableTreeContentProvider

All Implemented Interfaces:

IPageFlowScopeAdapter, IAddressableTableContentProvider, IContentProvider, IFilterableTableContentProvider, IRefreshable, IRefreshableContentProvider, ISelectableTableContentProvider, ISortableTableContentProvider, ITableContentProvider, ITransactionalContentProvider, IUpdateableContentProvider, IUpdateableTableContentProvider, ITreeContentProvider

public class TableTreeContentProvider
extends PageFlowScopeAdapter
implements ITreeContentProvider, IRefreshableContentProvider, ISortableTableContentProvider, IFilterableTableContentProvider, ISelectableTableContentProvider, ITransactionalContentProvider, IUpdateableTableContentProvider

Adapts an IAddressableTableContentProvider to an ITreeContentProvider. The table content provider must provide the rows in proper depth-first tree order (contrast this with other tree providers, such as ListTreeContentProvider, which are able to automatically re-order rows into depth-first tree order). For each of the following properties, either the getter method must be overriden, or this instance must be supplied with the corresponding --FieldName property:

• rootIds
• depth
• parentId
• childIds
• hasChildren
• firstChild
• lastChild

This relies on the underlying table content provider to implement any IRefreshableContentProvider, ISortableTableContentProvider, ISelectableTableContentProvider, ITransactionalContentProvider, IFilterableTableContentProvider, or IUpdateableTableContentProvider functionality, if used.
