Application No. 08/655,879
to its dependent. Because a component can be both a guardian and a dependent,
upon receiving a notification that it should change state, a guardian evaluates the states
of its guardians. Depending on the states of its guardians, the guardian may change
state but delay notifying its dependents of the change. (Id. at 10.)
A further understanding of the invention can be achieved by reading the following
claim.
10. A computer-implemented method for propagating state changes in a
message-driven computer program comprising:
(a) receiving, in a computer, a first notification signal indicating that
an event has occurred;
(b) transitioning a first component of an application program
executing in the computer from a current state to a new state in response
to the first notification signal;
(c) evaluating the state of a third component of the application
program to determine if the transition of the first component to the new
state should be propagated to a second component of the application
program, wherein the second component is dependent on the first
component;
(d) delaying propagating a second notification signal that indicates
the state transition from the first component to the second component
until the state of the third component indicates that the propagation should
occur; and
(e) propagating the second notification signal from the first
component to the second component by setting a flag in the second
component, wherein the flag represents the state of the first component.
