Subject [Jakarta-commons Wiki] Update of "Chain" by JohnMunsch

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Jakarta-commons Wiki" for change notification.

The following page has been changed by JohnMunsch:

  The Gang of Four's Chain of Responsibility (COR) behavioral design pattern is interesting
and commonly used to model a set of operations. Each operation needs to be modeled as a command
object and linked to others to form a chain. The command objects act upon some data and indicate
whether the control should get passed to the next command in the chain. The benefit is that
an operation can be added or removed easily without changing code. The complete article can
be found here
+ A fairly comprehensive pair of articles which focus __only__ on the Commons Chain is at
O'Reilly's OnJava site:

Commons Chain, Part 1]

Commons Chain, Part 2]
