Eclipse Platform
Release 3.5

org.eclipse.update.configuration
Class LocalSystemInfo

java.lang.Object
  extended by 
org.eclipse.update.configuration.LocalSystemInfo

Deprecated. The org.eclipse.update component has been replaced by Equinox p2. This provisional API was never promoted to stable API, and may be removed from a future release of the platform.

public class LocalSystemInfo
extends Object

Utility class providing local file system information. The class attempts to load a native library implementation of its methods. If successful, the method calls are delegated to the native implementation. Otherwise a default non-native implementation is used. *

Note: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Since:
2.0
See Also:
ILocalSystemInfoListener

getFreeSpace

public static long getFreeSpace(
File path)
Deprecated. 
Determines available free space on a volume. Returns the amount of free space available to this user on the volume containing the specified path. The method takes into account any space quotas or other native mechanisms that may restrict space usage on a given volume.

Parameters:
path - file path. May contain path elements beyond the volume "root"
Returns:
the amount of free space available (in units of Kbyte), or an indication the size is not known

Deprecated. 
Remove local system change listener

Parameters:
listener - change listener
Since:
2.0

Note: This method is part of an interim API that is still under development and expected to change significantly before reaching stability.

Notify listeners of change.

Parameters:
volume - the volume representing the change file system structure. Any current paths beyond the specified "root" file of the volume are assumed to be invalidated.
changeType - type of the change that occured.
