| <P > |
| The <a href="../reference/extension-points/org_eclipse_core_resources_refreshProviders.html"><b>org.eclipse.core.resources.refreshProviders</b></a> |
| extension point allows plug-ins to register and implement their own mechanisms for monitoring the external file system |
| and refreshing the workspace appropriately. This extension point is intended for plug-ins that implement |
| specialized, often native, schemes for monitoring file system changes.</P> |
| <p> |
| The plug-in fragment <b>org.eclipse.core.resources.win32</b> implements a native refresh monitor based on |
| file system callbacks. A more naive refresh monitor based on polling is defined for other platforms. |
| </p> |
| <p>The following snippet shows the definition for this extension in the <b>org.eclipse.core.resources.win32</b> |
| fragment. |
| </p> |
| <pre> <extension |
| id="win32" |
| point="org.eclipse.core.resources.refreshProviders"> |
| <refreshProvider |
| name="%win32MonitorFactoryName" |
| <b>class="org.eclipse.core.internal.resources.refresh.win32.Win32RefreshProvider"</b>> |
| </refreshProvider> |
| </extension> |
| </pre> |
| <p>The <b>class</b> attribute must be a class that extends |
| <b><a href="../reference/api/org/eclipse/core/resources/refresh/RefreshProvider.html">RefreshProvider</a></b>. |
| This class is responsible for installing a monitor on a specific resource and its resource subtree if it is a |
| project or folder. The monitor must implement |
| <b><a href="../reference/api/org/eclipse/core/resources/refresh/IRefreshMonitor.html">IRefreshMonitor</a></b>. |
