Method Details

evaluate

boolean evaluate()
          throws JmriException

Evaluate this expression.

This method must ensure that the value is not a Double.NaN, negative infinity or positive infinity. If that is the case, it must throw an IllegalArgumentException before checking if an error has occured.

Specified by:

evaluate in interface DigitalExpression

Returns:

the result of the evaluation

Throws:

JmriException - when an exception occurs

getLastResult

boolean getLastResult()

Get the last result of the evaluation.

Returns:

the last result
