Class RangeValidator

java.lang.Object
  extended by org.mbari.siam.utils.RangeValidator

public class RangeValidator
extends java.lang.Object

The RangeValidator evaluates the value of its input against a specified range of values. The output is valid if the value is within the specified range. If the input value is outside the valid range, there are several options, set by a member variable: - REJECT : reject the value; do not change output - USE_LAST_VALID : output last valid input value - USE_AVERAGE : average up to _average_n previous valid values - USE_CONSTANT : use the same constant value This class is intended to be immutable: if you want a different one, create a new one.
