      • CostMatrixEditor

        public CostMatrixEditor()
        Constructs a new CostMatrixEditor.

    • Method Detail

      • setValue

        public void setValue​(java.lang.Object value)
        Sets the value of the CostMatrix to be edited.
        Specified by:
        setValue in interface java.beans.PropertyEditor
        Parameters:
        value - a CostMatrix object to be edited

      • getValue

        public java.lang.Object getValue()
        Gets the cost matrix that is being edited.
        Specified by:
        getValue in interface java.beans.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 java.beans.PropertyEditor
        Returns:
        true

      • paintValue

        public void paintValue​(java.awt.Graphics gfx,
                       java.awt.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 java.beans.PropertyEditor
        Parameters:
        gfx - the graphics context to draw the representation to
        box - the bounds within which the representation should fit.

      • getJavaInitializationString

        public java.lang.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 java.beans.PropertyEditor
        Returns:
        the initialization string

      • getAsText

        public java.lang.String getAsText()
        Some objects can be represented as text, but a cost matrix cannot.
        Specified by:
        getAsText in interface java.beans.PropertyEditor
        Returns:
        null

      • setAsText

        public void setAsText​(java.lang.String text)
        Some objects can be represented as text, but a cost matrix cannot.
        Specified by:
        setAsText in interface java.beans.PropertyEditor
        Parameters:
        text - ignored
        Throws:
        java.lang.IllegalArgumentException - always throws an IllegalArgumentException

      • getTags

        public java.lang.String[] getTags()
        Some objects can return tags, but a cost matrix cannot.
        Specified by:
        getTags in interface java.beans.PropertyEditor
        Returns:
        null

      • getCustomEditor

        public java.awt.Component getCustomEditor()
        Gets a GUI component with which the user can edit the cost matrix.
        Specified by:
        getCustomEditor in interface java.beans.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 java.beans.PropertyEditor
        Returns:
        true

      • addPropertyChangeListener

        public void addPropertyChangeListener​(java.beans.PropertyChangeListener listener)

        Parameters:
        listener - a new listener to add to the list

      • removePropertyChangeListener

        public void removePropertyChangeListener​(java.beans.PropertyChangeListener listener)
        Removes an object from the list of those that wish to be informed when the cost matrix changes.
