## Field Detail

### _changedColor

    protected Color _changedColor

  The color to render an expression if it changes between steps.

### _defaultColor

    protected Color _defaultColor

  The default color to render an expression

## Constructor Detail

### AbstractExpressionValueCellRenderer

    public AbstractExpressionValueCellRenderer()

  The default constructor for an `AbstractExpressionValueCellRenderer`.

## Method Detail

### configureLabel(JLabel) Method

    protected abstract void configureLabel(JLabel label)

The method that actually sets-up the label with the expression value. Subclasses should set the text correctly, as well as set the foreground color as appropriate.

#### Parameters

label
  the `JLabel``` to show the expression value in.

### getTableCellRendererComponent(JTable, Object, boolean, boolean, int, int) Method

    public Component getTableCellRendererComponent(JTable table,
                                                   Object o,
                                                   boolean isSelected,
