org.openide.filesystems
Class Repository

java.lang.Object
  org.openide.filesystems.Repository

All Implemented Interfaces:

Serializable

---

public class Repository
extends Object
implements Serializable

Holder for system filesystem, used for most of NetBeans' runtime configuration. There is only one useful thing to do with this class:

 FileSystem sfs = Repository.getDefault().getDefaultFileSystem();
 // now use somehow, e.g.
 FileObject menus = sfs.findResource("Menu");
 // ...
 

Formerly (NB 3.x) contained a list of mounted filesystems. This functionality is no longer used and is now deprecated.

Constructor Detail

Repository

public Repository(FileSystem def)

Creates new instance of filesystem pool and registers it as the default one. Also registers the default filesystem.

Parameters:

def - the default filesystem

Method Detail

getDefault

public static Repository getDefault()

Access method to get default instance of repository in the system. The instance is either taken as a result of org.openide.util.Lookup.getDefault ().lookup (Repository.class) or (if the lookup query returns null) a default instance is created.

Returns:

default repository for the system

---

getDefaultFileSystem

public final FileSystem getDefaultFileSystem()

Gets the NetBeans default (system, configuration) filesystem.

Returns:

the default filesystem

---

addFileSystem

@Deprecated
public final void addFileSystem(FileSystem fs)

Deprecated. Please use the ClassPath API instead.

Adds new filesystem to the pool. Note that a filesystem cannot be assigned to more than one file system pool at one time (though currently there is only one pool anyway). At any given time, no two filesystems in the pool may share the same name (unless all but one are invalid). To be sure, that filesystem was really added in Repository, then test that FileSystem is valid.

Parameters:

fs - filesystem to add

---

removeFileSystem

@Deprecated
public final void removeFileSystem(FileSystem fs)

Deprecated. Please use the ClassPath API instead.

Removes a filesystem from the pool.

Parameters:

fs - filesystem to remove

---

reorder

@Deprecated
public final void reorder(int[] perm)

Deprecated. Please use the ClassPath API instead.

Reorders FileSystems by given permutation. For example, if there are three filesystems, new int[] {2, 0, 1} cycles the filesystems forwards.

Parameters:

perm - an array of integers

Throws:

IllegalArgumentException - if the array is not a permutation, or is not the same length as the current number of filesystems in the pool

---

getFileSystems

@Deprecated
public final Enumeration<? extends FileSystem> getFileSystems()

Deprecated. Please use the ClassPath API instead.

Returns enumeration of all filesystems.

Returns:

enumeration of type FileSystem

---

fileSystems

@Deprecated
public final Enumeration<? extends FileSystem> fileSystems()

Deprecated. Please use the ClassPath API instead.

Returns enumeration of all filesystems.

Returns:

enumeration of type FileSystem

---

toArray

@Deprecated
public final FileSystem[] toArray()

Deprecated. Please use the ClassPath API instead.

Returns a sorted array of filesystems.

Returns:

a sorted array of filesystems

---

findFileSystem

@Deprecated
public final FileSystem findFileSystem(String systemName)

Deprecated. Please use the ClassPath API instead.

Finds filesystem when only its system name is known.

Parameters:

systemName - name of the filesystem

Returns:

the filesystem or null if there is no such filesystem

---

writeExternal

@Deprecated
public final void writeExternal(ObjectOutput oos)
                         throws IOException

Deprecated. Unused.

Saves pool to stream by saving all filesystems. The default (system) filesystem, or any persistent filesystems, are skipped.

Parameters:

oos - object output stream

Throws:

IOException - if an error occures

---

readExternal

@Deprecated
public final void readExternal(ObjectInput ois)
                        throws IOException,
                               ClassNotFoundException

Deprecated. Unused.

Reads object from stream. Reads all filesystems. Persistent and system filesystems are untouched; all others are removed and possibly reread.

Parameters:

ois - object input stream

Throws:

IOException - if an error occures

ClassNotFoundException - if read class is not found

---

find

@Deprecated
public final FileObject find(String aPackage,
                                        String name,
                                        String ext)

Deprecated. Please use the ClassPath API instead.

Finds file when its name is provided. It scans in the list of filesystems and asks them for the specified file by a call to find. The first object that is found is returned or null if none of the filesystems contain such a file.

Parameters:

aPackage - package name where each package is separated by a dot

name - name of the file (without dots) or null if one wants to obtain the name of a package and not a file in it

ext - extension of the file or null if one needs a package and not a file name

Returns:

FileObject that represents file with given name or null if the file does not exist

---

findResource

@Deprecated
public final FileObject findResource(String name)

Deprecated. Please use the ClassPath API instead.

Searches for the given resource among all filesystems.

Parameters:

name - a name of the resource

Returns:

file object or null if the resource can not be found

See Also:

FileSystem.findResource(java.lang.String)

---

findAllResources

@Deprecated
public final Enumeration<? extends FileObject> findAllResources(String name)

Deprecated. Please use the ClassPath API instead.

Searches for the given resource among all filesystems, returning all matches.

Parameters:

name - name of the resource

Returns:

enumeration of FileObjects

---

findAll

@Deprecated

                                                                  String name,

Deprecated. Please use the ClassPath API instead.

Finds all files among all filesystems matching a given name, returning all matches. All filesystems are queried with FileSystem.find(java.lang.String, java.lang.String, java.lang.String).

Parameters:

aPackage - package name where each package is separated by a dot

name - name of the file (without dots) or null if one wants to obtain the name of a package and not a file in it

ext - extension of the file or null if one needs a package and not a file name

Returns:

enumeration of FileObjects

---

Deprecated. Please use the ClassPath API instead.

Adds new listener.

Parameters:

list - the listener
