| 描述 |
Avalon Excalibur's resource management code allows you to be notified when a resource has changed. There
are two methods of resource management: active and passive. Passive resource management acts as a holder
for resources, and after the resource has been modified through it's normal API, notification goes to all
listeners. Active resource management does the same, but it also polls the resources periodically to see
if the resource was modified through an external method. Active resource management is perfect for
monitoring files because they can be modified by external programs, and your program will be notified when
the change occurs instead of constantly polling it. |
