TRangeValidator class

TRangeValidator tests whether an input value is within a specified range.

TRangeValidator uses three key properties to perform its validation. The MinValue and MaxValue properties specify the minimum and maximum values of the valid range. The DataType property is used to specify the data type of the value and the minimum and maximum range values. These values are converted to this data type before the validation operation is performed. The following value types are supported:

  • Integer A 32-bit signed integer data type.
  • Float A double-precision floating point number data type.
  • Date A date data type. The date format can be specified by setting DateFormat property, which must be recognizable by TSimpleDateFormatter. If the property is not set, the GNU date syntax is assumed.
  • String A string data type.
  • StringLength check for string length.
If StrictComparison is true, then the ranges are compared as strictly less than the max value and/or strictly greater than the min value.

The TRangeValidator allows a special DataType "StringLength" that can be used to verify minimum and maximum string length. The Charset property can be used to force a particular charset for comparison. Otherwise, the application charset is used and is defaulted as UTF-8.
