Eclipse Platform
Release 3.5

org.eclipse.core.resources
Class ResourcesPlugin

java.lang.Object
  extended by 

org.eclipse.core.runtime.Plugin
      extended by 
org.eclipse.core.resources.ResourcesPlugin
All Implemented Interfaces:
BundleActivator

public final class ResourcesPlugin
extends Plugin

The plug-in runtime class for the Resources plug-in. This is the starting point for all workspace and resource manipulation. A typical sequence of events would be for a dependent plug-in to call ResourcesPlugin.getWorkspace(). Doing so would cause this plug-in to be activated and the workspace (if any) to be loaded from disk and initialized.

Restriction:
This class is not intended to be instantiated by clients.

Constructor Detail

ResourcesPlugin

public ResourcesPlugin()
Constructs an instance of this plug-in runtime class.

An instance of this plug-in runtime class is automatically created when the facilities provided by the Resources plug-in are required. Clients must never explicitly instantiate a plug-in runtime class.

Method Detail

getEncoding

public static 
String getEncoding()
Returns the encoding to use when reading text files in the workspace. This is the value of the PREF_ENCODING preference, or the file system encoding (System.getProperty("file.encoding")) if the preference is not set.

Note that this method does not check whether the result is a supported encoding. Callers should be prepared to handle UnsupportedEncodingException where this encoding is used.

Returns:
the encoding to use when reading text files in the workspace
See Also:
UnsupportedEncodingException

getPlugin

public static 
ResourcesPlugin getPlugin()
Returns the Resources plug-in.

Returns:
the single instance of this plug-in runtime class

getWorkspace

public static 
IWorkspace getWorkspace()
Returns the workspace. The workspace is not accessible after the resources plug-in has shutdown.

Returns:
the workspace that was created by the single instance of this plug-in class.

stop

public void stop(
BundleContext context)
          throws 
Exception
This implementation of the corresponding BundleActivator method closes the workspace without saving.

Specified by:
stop in interface BundleActivator
Overrides:
stop in class Plugin
Parameters:
context - the bundle context for this plug-in
Throws:
Exception - if this method fails to shut down this plug-in
See Also:
BundleActivator.stop(BundleContext)

start

public void start(
BundleContext context)
           throws 
Exception
This implementation of the corresponding BundleActivator method opens the workspace.

Specified by:
start in interface BundleActivator
Overrides:
start in class Plugin
Parameters:
context - the bundle context for this plug-in
Throws:
Exception - if this plug-in did not start up properly
See Also:
BundleActivator.start(BundleContext)
