Method Detail

getRootHub

public static Hub getRootHub(Hub thisHub)

If this is a recursive hub with an owner, then the root hub will be returned, else null.

setRootHub

public static void setRootHub(Hub thisHub,
                              boolean b)

Used for recursive object relationships, to set the root Hub. A recursive relationship is where an object has a reference to many children (Hub) of objects that are the same class.

The root is the Hub that where the reference to a parent object is null. OAObject and Hub will automatically keep/put objects in the correct Hub based on the parent reference.

Note: the root Hub is automatically set when a master object owns a Hub.
Example:
If a Class "Test" is recursive and a Class Employee has many "Tests", then each Employee object will own a recursive list of "Test" Hubs. Each "Test" object under the Employee object will have a reference to the Employee object.

Calls OAObjectInfo to set this hub as the root hub for other recursive hubs in same object class. If this is not a recursive hub then an exception will be thrown.

Parameters:

b - if true then set thisHub as the root, else remove as the rootHub.
