Class ShortValidator
- Serializable
public class ShortValidator
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
java.text.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 sucessfully 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:
- 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

ShortValidator
public ShortValidator()
Construct a strict instance.
ShortValidator
public ShortValidator(boolean strict,
int formatType)
Construct an instance with the specified strict setting
and format type.
The
formatType
specified what type of
NumberFormat
is 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).
strict
- true
if strict
Format
parsing should be used.formatType
- The NumberFormat
type to
create for validation, default is STANDARD_FORMAT.
