Method Detail

getInstance

public static DummyFileSystem getInstance()

createRoot

public VirtualFile createRoot(java.lang.String name)

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

extractPresentableUrl

public java.lang.String extractPresentableUrl(java.lang.String path)

Description copied from class: VirtualFileSystem

Fetches presentable URL of file with the given path in this file system.

Overrides:

extractPresentableUrl in class VirtualFileSystem

Parameters:

path - the path to get presentable URL for

Returns:

presentable URL

See Also:

VirtualFile.getPresentableUrl()

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

deleteFile

public void deleteFile(java.lang.Object requestor,
                       VirtualFile vFile)
                throws java.io.IOException

Description copied from class: VirtualFileSystem

Implementation of deleting files in this file system

Overrides:

deleteFile in class DeprecatedVirtualFileSystem

Throws:

java.io.IOException

See Also:

VirtualFile.delete(Object)

renameFile

public void renameFile(java.lang.Object requestor,
                       VirtualFile vFile,
                       java.lang.String newName)

Description copied from class: VirtualFileSystem

Implementation of renaming files in this file system

Overrides:

renameFile in class DeprecatedVirtualFileSystem

See Also:

VirtualFile.rename(Object,String)

createChildFile

public VirtualFile createChildFile(java.lang.Object requestor,
                                   VirtualFile vDir,
                                   java.lang.String fileName)
