Constructor Detail

CostMatrixEditor

public CostMatrixEditor()

Constructs a new CostMatrixEditor.

Method Detail

setValue

public void setValue(Object value)

Sets the value of the CostMatrix to be edited.

Specified by:

setValue in interface PropertyEditor

Parameters:

value - a CostMatrix object to be edited

getValue

public Object getValue()

Gets the cost matrix that is being edited.

Specified by:

getValue in interface PropertyEditor

Returns:

the edited CostMatrix object

isPaintable

public boolean isPaintable()

Indicates whether the object can be represented graphically. In this case it can.

Specified by:

isPaintable in interface PropertyEditor

Returns:

true

paintValue

public void paintValue(Graphics gfx,
              Rectangle box)

Paints a graphical representation of the object. For the cost matrix it prints out the text "X x X matrix", where X is the size of the matrix.

Specified by:

paintValue in interface PropertyEditor

Parameters:

gfx - the graphics context to draw the representation to

box - the bounds within which the representation should fit.

getJavaInitializationString

public String getJavaInitializationString()

Returns the Java code that generates an object the same as the one being edited. Unfortunately this can't be done in a single line of code, so the code returned will only build a default cost matrix of the same size.

Specified by:

getJavaInitializationString in interface PropertyEditor

Returns:

the initialization string

getAsText

public String getAsText()

Some objects can be represented as text, but a cost matrix cannot.

Specified by:

getAsText in interface PropertyEditor

Returns:

null

setAsText

public void setAsText(String text)

Some objects can be represented as text, but a cost matrix cannot.

Specified by:

setAsText in interface PropertyEditor

Parameters:

text - ignored

Throws:

IllegalArgumentException - always throws an IllegalArgumentException

getTags

public String[] getTags()

Some objects can return tags, but a cost matrix cannot.

Specified by:

getTags in interface PropertyEditor

Returns:

null

getCustomEditor

public Component getCustomEditor()

Gets a GUI component with which the user can edit the cost matrix.

Specified by:

getCustomEditor in interface PropertyEditor

Returns:

an editor GUI component

supportsCustomEditor

public boolean supportsCustomEditor()

Indicates whether the cost matrix can be edited in a GUI, which it can.

Specified by:

supportsCustomEditor in interface PropertyEditor

Returns:

true

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds an object to the list of those that wish to be informed when the cost matrix changes.

Specified by:

addPropertyChangeListener in interface PropertyEditor

Parameters:

listener - a new listener to add to the list

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes an object from the list of those that wish to be informed when the cost matrix changes.

Specified by:

removePropertyChangeListener in interface PropertyEditor

Parameters:

listener - the listener to remove from the list
