Class FileData

java.lang.Object

net.sf.jguiraffe.examples.tutorial.model.FileData

All Implemented Interfaces:

Comparable<FileData>

public class FileData
extends Object
implements Comparable<FileData>

A simple data class representing a file (or sub directory) in a directory.

Objects of this type are used by the model of the table control. Each instance represents one row in the table. An instance wraps a File object and provides bean-style get methods for it. (The API of File does not always conform to the Java Beans standard.)

FileData

public FileData(String name,
                Object icon)

Creates a new instance of FileData that does not represent a file. Objects of this type are used as placeholders if no real data is available, e.g. if data has to be loaded first.

Parameters:

name - the name to be displayed

icon - an icon

Method Detail

getFile

public File getFile()

Returns the associated File object. If this object represents a special entry which is not associated with a file, result is null.

Returns the date this file was modified.

Returns:

the last modification date (can be null)

getSize

public long getSize()

Returns the size of this file.

Returns:

the size

equals

public boolean equals(Object obj)

Compares this object with another one. Two instances of FileData are equal if they refer to the same file.

Overrides:

equals in class Object

Parameters:

obj - the object to compare to

Returns:

a flag whether the objects are equal

hashCode

public int hashCode()

Returns a hash code for this object.

Overrides:

hashCode in class Object

Returns:

a hash code

toString

a string for this object

compareTo

public int compareTo(FileData o)

A special compareTo() implementation. Files are sorted alphabetically by their names. Directories are sorted before plain files.

Specified by:

compareTo in interface Comparable<FileData>

Parameters:

o - the other FileData object

Returns:

a value indicating the order of these objects
