Method Detail

getProtocol

public java.lang.String getProtocol()

Description copied from class: VirtualFileSystem

Gets the protocol for this file system. Protocols should differ for all file systems. Should be the same as corresponding KeyedLazyInstanceEP.key.

Specified by:

getProtocol in class VirtualFileSystem

Returns:

String representing the protocol

See Also:

VirtualFile.getUrl(), VirtualFileManager.getFileSystem(java.lang.String)

findFileByPath

public VirtualFile findFileByPath(java.lang.String path)

Description copied from class: VirtualFileSystem

Searches for the file specified by given path. Path is a string which uniquely identifies file within given VirtualFileSystem. Format of the path depends on the concrete file system. For LocalFileSystem it is an absolute path (both Unix- and Windows-style separator chars are allowed).

Specified by:

findFileByPath in class VirtualFileSystem

Parameters:

path - the path to find file by

Returns:

a virtual file if found, null otherwise

splitPath

protected Couple<java.lang.String> splitPath(java.lang.String path)

refresh

public void refresh(boolean asynchronous)

Description copied from class: VirtualFileSystem

Refreshes the cached information for all files in this file system from the physical file system.

If asynchronous is false this method should be only called within write-action. See Application.runWriteAction(java.lang.Runnable).

Specified by:

refresh in class VirtualFileSystem

Parameters:

asynchronous - if true then the operation will be performed in a separate thread, otherwise will be performed immediately

See Also:

VirtualFile.refresh(boolean, boolean), VirtualFileManager.syncRefresh(), VirtualFileManager.asyncRefresh(java.lang.Runnable)

refreshAndFindFileByPath

public VirtualFile refreshAndFindFileByPath(java.lang.String path)

Description copied from class: VirtualFileSystem

Refreshes only the part of the file system needed for searching the file by the given path and finds file by the given path.

This method is useful when the file was created externally and you need to find VirtualFile corresponding to it.

If this method is invoked not from Swing event dispatch thread, then it must not happen inside a read action. The reason is that then the method call won't return until proper VFS events are fired, which happens on Swing thread and in write action. So invoking this method in a read action would result in a deadlock.

Specified by:

refreshAndFindFileByPath in class VirtualFileSystem

Parameters:

path - the path

Returns:

VirtualFile if the file was found, null otherwise

clearHandlersCache

public void clearHandlersCache()
