short validator
Description
Field Validator that checks if the short specified is within a certain range.
Parameters
fieldName- The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required.min- the minimum value (if none is specified, it will not be checked).max- the maximum value (if none is specified, it will not be checked).parse- if set to true, minExpression and maxExpression will be evaluated to find min/max.minExpression- expression to calculate the minimum value (if none is specified, it will not be checked).maxExpression- expression to calculate the maximum value (if none is specified, it will not be checked).
You can either use the min / max value or minExpression / maxExpression (when parse is set to true) - using
expression can be slightly slower, see the example below.
Warning: do not use
${minExpression}and${maxExpression}as an expression as this will turn into infinitive loop!
