Class ProvidedExtensions

java.lang.Object

org.netbeans.modules.masterfs.providers.ProvidedExtensions

All Implemented Interfaces:

InterceptionListener

public class ProvidedExtensions
extends Object
implements InterceptionListener

Encapsulate a group of individual factory methods that are responsible for creating objects of specific interfaces. If subclassed and provided by BaseAnnotationProvider.getInterceptionListener() then individual instances will be called by MasterFileSystem There may exist more than one instance of ProvidedExtensions at a given moment and therefore there is defined for every method wheter will be called by MasterFileSystem for every present instance or just for the first one.

beforeChange

public void beforeChange(FileObject fo)

fileLocked

public void fileLocked(FileObject fo)

Throws:

IOException

fileUnlocked

public void fileUnlocked(FileObject fo)

public Object getAttribute(File file,

refreshRecursively

public long refreshRecursively(File dir,

                               List<? super File> children)

Allows versioning system to exclude some children from recursive listening check. Also notifies the versioning whenever a refresh is required and allows the versiniong to provide special timestamp for a directory.

Default implementation of this method returns -1.

Parameters:

dir - the directory to check timestamp for

lastTimeStamp - the previously known timestamp or -1

children - add subfiles that shall be interated into this array

Returns:

the timestamp that shall represent this directory, it will be compared with timestamps of all children and the newest one will be kept and next time passed as lastTimeStamp. Return 0 if the directory does not have any special timestamp. Return -1 if you are not providing any special implementation

Since:

2.23

priorityIO

public static <T> T priorityIO(Callable<T> run)

Allows registered exceptions to execute some I/O priority action. This will stop all other "idle I/O" operations (like background refresh after window is activated).

Parameters:

run - the Callable to run

Throws:

Exception - the exception thrown by the callable
