Class BoundChildrenNode

java.lang.Object
  com.webmethods.caf.faces.data.tree.object.DefaultNode
      com.webmethods.caf.faces.data.tree.object.BoundChildrenNode

All Implemented Interfaces:

INode, Serializable

public class BoundChildrenNode
extends DefaultNode

INode implementation that wraps an arbitrary java object, creating a tree structure defined by a set of arbitrary children bindings. If the object has children, one of the configured children binding expressions should resolve to the List or Object[] (array) of the object's children.

This node must be initialized with the java object to wrap, a row variable (used in binding expressions to indicate the current node), a row id binding (a value-binding which evaluates to the unique id of the current node), and a children binding (a value-binding which evaluates to the list or array of children for the current node). Unless this node is a root node, it must also be initialized with its direct parent INode.

BoundChildrenNode

public BoundChildrenNode()

New uninitialized node. This node must be initialized with the java object to wrap, a row variable (used in binding expressions to indicate the current node), a row id binding (a value-binding which evaluates to the unique id of the current node), and a children binding (a value-binding which evaluates to the list or array of children for the current node). Unless this node is a root node, it must also be initialized with its direct parent INode.

BoundChildrenNode

public BoundChildrenNode(Object data)

New node, partially initialized with a java object to wrap. This node must be initialized additionally with a row variable (used in binding expressions to indicate the current node), a row id binding (a value-binding which evaluates to the unique id of the current node), and a children binding (a value-binding which evaluates to the list or array of children for the current node). Unless this node is a root node, it must also be initialized with its direct parent INode.

                         String dataVariable,
                         String idBinding,
                         String childrenBinding)

New node, initialized with a java object to wrap, a row variable (used in binding expressions to indicate the current node), a row id binding (a value-binding which evaluates to the unique id of the current node), and a children binding (a value-binding which evaluates to the list or array of children for the current node). Unless this node is a root node, it must also be initialized with its direct parent INode.

New node, initialized with a java object to wrap, a row variable (used in binding expressions to indicate the current node), a row id binding (a value-binding which evaluates to the unique id of the current node), and a children binding (a value-binding which evaluates to the list or array of children for the current node).

                         INode parent)

New node, initialized with a java object to wrap, a row variable (used in binding expressions to indicate the current node), a row id binding (a value-binding which evaluates to the unique id of the current node), a children binding (a value-binding which evaluates to the list or array of children for the current node), and its direct parent INode.
