Method Detail

getInstance

public static ManagingFS getInstance()

readAttribute

public abstract java.io.DataInputStream readAttribute(VirtualFile file,
                                                      FileAttribute att)

writeAttribute

public abstract java.io.DataOutputStream writeAttribute(VirtualFile file,
                                                        FileAttribute att)

getModificationCount

public abstract int getModificationCount(VirtualFile fileOrDirectory)

Returns:

a number that's incremented every time something changes for the file: name, size, flags, content. This number is persisted between IDE sessions and so it'll always increase. This method invocation means disk access, so it's not terribly cheap.

getModificationCount

public abstract int getModificationCount()

Returns:

a number that's incremented every time something changes in the VFS, i.e. file hierarchy, names, flags, attributes, contents. This only counts modifications done in current IDE session.

See Also:

getStructureModificationCount(), getFilesystemModificationCount()

getStructureModificationCount

public abstract int getStructureModificationCount()

Returns:

a number that's incremented every time something changes in the VFS structure, i.e. file hierarchy or names. This only counts modifications done in current IDE session.

See Also:

getModificationCount()

getFilesystemModificationCount

public abstract int getFilesystemModificationCount()

Returns:

a number that's incremented every time modification count for some file is advanced, @see getModificationCount(VirtualFile). This number is persisted between IDE sessions and so it'll always increase. This method invocation means disk access, so it's not terribly cheap.

getCreationTimestamp

public abstract long getCreationTimestamp()

areChildrenLoaded

public abstract boolean areChildrenLoaded(VirtualFile dir)

wereChildrenAccessed

public abstract boolean wereChildrenAccessed(VirtualFile dir)

findRoot

public abstract NewVirtualFile findRoot(java.lang.String path,
                                        NewVirtualFileSystem fs)

getRoots

public abstract VirtualFile [] getRoots()

getRoots

public abstract VirtualFile [] getRoots(NewVirtualFileSystem fs)

getLocalRoots

public abstract VirtualFile [] getLocalRoots()

findFileById

public abstract VirtualFile findFileById(int id)
