Constructor Detail

EweFile.EweEntryFile

public EweFile.EweEntryFile(EweFile ef)

Create an EweEntryFile for a particular EweFile. You can then call getNew(null,"/") to get a representation of the root directory in the EweFile.

Parameters:

ef - the EweFile

EweFile.EweEntryFile

public EweFile.EweEntryFile(EweFile ef,
                            Handle h)

Create an EweEntryFile for a particular EweFile. You can then call getNew(null,"/") to get a representation of the root directory in the EweFile.

Parameters:

ef - the EweFile

h - an optional handle that can be used to abort the construction.

Method Detail

getNew

public File getNew(File parent,
                   String file)

Description copied from class: FileBase

Get a new File object given the directory and new path. This is for objects which inherit from File. The default implementation of this will call getNewInstance() and then call set(File directory,String path). If you do not override getNew() you must override getNewInstance().

Overrides:

getNew in class FileBase

isValid

public boolean isValid()

exists

public boolean exists()

Description copied from class: File

Returns true if the file exists and false otherwise.

Specified by:

exists in class FileAdapter

isDirectory

public boolean isDirectory()

Description copied from class: File

Returns true if the file is a directory and false otherwise.

Specified by:

isDirectory in class FileAdapter

getLength

public int getLength()

Description copied from class: File

Returns the length of the file in bytes.

Specified by:

getLength in class FileAdapter

getSetModified

protected void getSetModified(Time time,
                              boolean doGet)

Description copied from class: FileBase

This gets/sets the modified time of the file. should not exist.

Overrides:

getSetModified in class FileAdapter

set

public void set(File parent,
                String file)

Description copied from class: FileAdapter

This is used to tell the File to represent a different File entity. By default all it does is call setFullPathName() so that the protected name variable represents the full path name. If your File representation has more state than just the full path name, then override this method to setup the new state.

Overrides:

set in class FileAdapter

startFind

protected int startFind(String mask)

Description copied from class: FileAdapter

This is used as the start point for listing. The method should begin the find operation and return a unique ID for the find operation.

Specified by:

startFind in class FileAdapter

findNext

protected Object findNext(int search)

Description copied from class: FileAdapter

This will find the next file in sequence given the search ID returned by startFind(). It can either return a File Object or the name of the file.

Specified by:

findNext in class FileAdapter

endFind

protected void endFind(int search)

Description copied from class: FileAdapter

This tells the File to free all resources associated with the find given the search ID returned by startFind().

Specified by:

endFind in class FileAdapter

getInfo

public Object getInfo(int value,
                      Object source,
                      Object resultDestination,
                      int options)

Description copied from class: File

This method is used to get extended information about the File or the File system in general. It is used with the INFO_ specifiers and options.

Overrides:

getInfo in class FileAdapter

toReadableStream

public Stream toReadableStream()
                        throws IOException

Description copied from class: FileBase

Create and return a Stream to use for reading from the File.

Overrides:

toReadableStream in class FileBase

Returns:

An open Steam that can be used for reading from the File.

Throws:

IOException - if an open stream could not be created.
