Constructor Summary

GenericArrayEditor()
Sets up the array editor.

Method Summary

void	addPropertyChangeListener(PropertyChangeListener l) Adds a PropertyChangeListener who will be notified of value changes.
String	getAsText() Returns null as we don't support getting/setting values as text.
Component	getCustomEditor() Returns the array editing component.
String	getJavaInitializationString() Supposedly returns an initialization string to create a classifier identical to the current one, including it's state, but this doesn't appear possible given that the initialization string isn't supposed to contain multiple statements.
String[]	getTags() Returns null as we don't support getting values as tags.
Object	getValue() Gets the current object array.
boolean	isPaintable() Returns true to indicate that we can paint a representation of the string array.
static void	main(String[] args) Tests out the array editor from the command line.
static Object	makeCopy(Object source) Makes a copy of an object using serialization.
void	paintValue(Graphics gfx, Rectangle box) Paints a representation of the current classifier.
void	removePropertyChangeListener(PropertyChangeListener l) Removes a PropertyChangeListener.
void	setAsText(String text) Returns null as we don't support getting/setting values as text.
void	setValue(Object o) Sets the current object array.
boolean	supportsCustomEditor() Returns true because we do support a custom editor.

Constructor Detail

GenericArrayEditor

public GenericArrayEditor()

Sets up the array editor.

Method Detail

setValue

public void setValue(Object o)

Sets the current object array.

Specified by:

setValue in interface PropertyEditor

Parameters:

o - an object that must be an array.

getValue

public Object getValue()

Gets the current object array.

Specified by:

getValue in interface PropertyEditor

Returns:

the current object array

getJavaInitializationString

public String getJavaInitializationString()

Supposedly returns an initialization string to create a classifier identical to the current one, including it's state, but this doesn't appear possible given that the initialization string isn't supposed to contain multiple statements.

Specified by:

getJavaInitializationString in interface PropertyEditor

Returns:

the java source code initialisation string

isPaintable

public boolean isPaintable()

Returns true to indicate that we can paint a representation of the string array.

Specified by:

isPaintable in interface PropertyEditor

Returns:

true

paintValue

public void paintValue(Graphics gfx,
                       Rectangle box)

Paints a representation of the current classifier.

Specified by:

paintValue in interface PropertyEditor

Parameters:

gfx - the graphics context to use

box - the area we are allowed to paint into

getAsText

public String getAsText()

Returns null as we don't support getting/setting values as text.

Specified by:

getAsText in interface PropertyEditor

Returns:

null

setAsText

public void setAsText(String text)

Returns null as we don't support getting/setting values as text.

Specified by:

setAsText in interface PropertyEditor

Parameters:

text - the text value

Throws:

IllegalArgumentException - as we don't support getting/setting values as text.

getTags

public String[] getTags()

Returns null as we don't support getting values as tags.

Specified by:

getTags in interface PropertyEditor

Returns:

null

supportsCustomEditor

public boolean supportsCustomEditor()

Returns true because we do support a custom editor.

Specified by:

supportsCustomEditor in interface PropertyEditor

Returns:

true

getCustomEditor

public Component getCustomEditor()

Returns the array editing component.

Specified by:

getCustomEditor in interface PropertyEditor

Returns:

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

Adds a PropertyChangeListener who will be notified of value changes.

Specified by:

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)

Removes a PropertyChangeListener.

Specified by:

makeCopy

public static Object makeCopy(Object source)

Makes a copy of an object using serialization.

Parameters:

source - the object to copy

Returns:

a copy of the source object, null if copying fails

main

public static void main(String[] args)

Tests out the array editor from the command line.

Parameters:
