All auto-refresh providers must subclass this class. A
RefreshProvider
is responsible for creating
IRefreshMonitor

it is capable of monitoring the file, or folder and subtree under the path that is provided.

protected IRefreshMonitor |
createPollingMonitor(IResource resource)
Creates a new refresh monitor that performs naive polling of the resource
in the file system to detect changes.
|
abstract IRefreshMonitor |
installMonitor(IResource resource,
IRefreshResult result)
Returns an
IRefreshMonitor that will monitor a resource. |

resetMonitors(IResource resource)
Resets the installed monitors for the given resource.
|
protected IRefreshMonitor createPollingMonitor(IResource resource)
This default monitor can be returned by subclasses when
installMonitor
is called.
If the returned monitor is not immediately returned from the installMonitor
method, then clients are responsible for telling the returned monitor to
stop polling when it is no longer needed. The returned monitor can be told to
stop working by invoking IRefreshMonitor.unmonitor(IResource)
.

the resource is an IContainer
the monitor will also

this provider cannot create a monitor for the given resource. The
provider may return the same monitor instance that has been provided for
other resources.
The monitor should send results and failures to the provided refresh result.
