All Implemented Interfaces:

com.compoze.common.IPagination, java.io.Serializable

public class ToDos

extends java.lang.Object

implements com.compoze.common.IPagination, java.io.Serializable

This class represents a to do. The to do collection may be used to iterate through to dos. By default, the to do colleciton is sorted by due date in ascending order.

The to do collection may also be used for searching. The following code segment shows how to reduce the to do that are returned in the collection to ones with a particular name and implies sorting:

 ToDoSession s = ToDoSession.getSession(user);
 ToDos	todos = s.getToDos();

 ToDoFilter filter = new ToDoFilter();
 filter.setSummary("Management Report");

 todos.setFilter(filter);
 todos.sort(SortOrder.ASCENDING, ToDoProperty.SUMMARY);

 Iterator	it = todos.todos().iterator();
 while(it.hasNext())
	{
	ToDo   td = (ToDo)it.next();
	...
  }
