Constructor Summary
`GenericArrayEditor()` Sets up the array editor.

Method Summary
`void` | `addPropertyChangeListener(java.beans.PropertyChangeListener l)` Adds a PropertyChangeListener who will be notified of value changes.
`java.lang.String` | `getAsText()` Returns null as we don't support getting/setting values as text.
`java.awt.Component` | `getCustomEditor()` Returns the array editing component.
`java.lang.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.
`java.lang.String[]` | `getTags()` Returns null as we don't support getting values as tags.
`java.lang.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(java.lang.String[] args)` Tests out the array editor from the command line.
`static java.lang.Object` | `makeCopy(java.lang.Object source)` Makes a copy of an object using serialization.
`void` | `paintValue(java.awt.Graphics gfx, java.awt.Rectangle box)` Paints a representation of the current classifier.
`void` | `removePropertyChangeListener(java.beans.PropertyChangeListener l)` Removes a PropertyChangeListener.
`void` | `setAsText(java.lang.String text)` Returns null as we don't support getting/setting values as text.
`void` | `setValue(java.lang.Object o)` Sets the current object array.
`boolean` | `supportsCustomEditor()` Returns true because we do support a custom editor.

    public GenericArrayEditor()

  Sets up the array editor.

Method Detail

### setValue

    public void setValue(java.lang.Object o)

  Sets the current object array.

  Specified by:
    `setValue` in interface `java.beans.PropertyEditor`

  Returns:
    the current object array

### getJavaInitializationString

    public java.lang.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 `java.beans.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 `java.beans.PropertyEditor`
  Returns:
    true

### paintValue

    public void paintValue(java.awt.Graphics gfx,
                           java.awt.Rectangle box)

  Paints a representation of the current classifier.

  Specified by:
    `paintValue` in interface `java.beans.PropertyEditor`
  Parameters:
    `gfx` - the graphics context to use
    `box` - the area we are allowed to paint into

### getAsText

    public java.lang.String getAsText()

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

    `getAsText` in interface `java.beans.PropertyEditor`
  Returns:
    null

### setAsText

    public void setAsText(java.lang.String text)

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

  Specified by:

  Parameters:
    `text` - the text value
  Throws:
    `java.lang.IllegalArgumentException` - as we don't support getting/setting values as text.

### getTags

  Specified by:
    `getTags` in interface `java.beans.PropertyEditor`
  Returns:
