                                org.outerj.expression.ExpressionContext expressionContext)
Parameters:
value - a value of a class supported by the ValidationRule implementation
expressionContext - many validation rules use the xReporter expression interpreter, the expressionContext allows to resolve variables used in these expressions.

                            boolean arrayType)
Description copied from interface: ValidationRule
