Class ShortValidator
- All Implemented Interfaces:
Serializable
Short Validation and Conversion routines (java.lang.Short).
This validator provides a number of methods for
validating/converting a String value to
a Short using NumberFormat
to parse either:
- using the default format for the default
Locale - using a specified pattern with the default
Locale - using the default format for a specified
Locale - using a specified pattern with a specified
Locale
Use one of the isValid() methods to just validate or
one of the validate() methods to validate and receive a
converted Short value.
Once a value has been successfully converted the following methods can be used to perform minimum, maximum and range checks:
minValue()checks whether the value is greater than or equal to a specified minimum.maxValue()checks whether the value is less than or equal to a specified maximum.isInRange()checks whether the value is within a specified range of values.
So that the same mechanism used for parsing an input value
for validation can be used to format output, corresponding
format() methods are also provided. That is you can
format either:

ShortValidator
Construct an instance with the specified strict setting and format type.
The
formatTypespecified what type ofNumberFormatis created - valid types are:- AbstractNumberValidator.STANDARD_FORMAT -to create standard number formats (the default).
- AbstractNumberValidator.CURRENCY_FORMAT -to create currency number formats.
- AbstractNumberValidator.PERCENT_FORMAT -to create percent number formats (the default).
- Parameters:
strict-trueif strictFormatparsing should be used.formatType- TheNumberFormattype to create for validation, default is STANDARD_FORMAT.
