public class DetailHub<TYPE>
extends Hub<TYPE>

A DetailHub is a Hub that automatically contains the object(s) of a property from the active object of another Hub (master). This is referred as a Master/Detail relationship.

Whenever the active object of the master Hub is changed, the Detail Hub will automatically be updated to include the objects of a property in the active object.

Example:
A Department Class has many Employees (using a Hub). A DetailHub can be created using a Hub of Department objects as the master Hub. This DetailHub will automatically contain the Employee objects for whichever Department is currenly the active object in the master Hub.

Using the diagram, the detail Hub is populated with the Employee objects from the Department that is the active object in the master Hub. Actually, the detail Hub is not really populated, but rather it uses the same Data that the Dept B Employee Hub is using. If an Employee object is added to the active Department's Employee Hub, the Detail Hub would also contain this Employee.

In this example, a UI Component (ex: JTable) could be setup to list the Department objects and another UI Component (ex: JTable) could list the Employee objects from the Department that is selected. If another Department is selected, then the JTable listing the Employees will show that Departments Employee objects.

 Hub hubDept = new Hub(Department.class);   // create new Hub for Department objects
 hubDept.select();      // select all departments from datasource
 Hub hubEmp = new HubDetail(hubDept, "Employees"); // create Hub that will automatically
                                                   //  contain the Employee objects
                                                   //  for the active Department
 // Or
 Hub hubEmp = new HubDetail(hubDept,"Employees", "lastName, firstName"); // sets sort order
