public class ByteValidator extends AbstractNumberValidator
Byte Validation and Conversion routines (java.lang.Byte
).
This validator provides a number of methods for
validating/converting a String
value to
a Byte
using java.text.NumberFormat
to parse either:
Locale
Locale
Locale
Locale
Use one of the isValid()
methods to just validate or
one of the validate()
methods to validate and receive a
converted Byte
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:
Locale
Locale
Locale
Locale

Construct an instance with the specified strict setting and format type.
The formatType
specified what type of
NumberFormat
is created - valid types
are:
Parameters: strict true
if strict
Format
parsing should be used. formatType The NumberFormat
type to
create for validation, default is STANDARD_FORMAT.
Returns: A singleton instance of the ByteValidator.
Parameters: value The Number
value to check. min The minimum value of the range. max The maximum value of the range.
Returns: true
if the value is within the
specified range.
Parameters: value The Number
value to check. min The minimum value of the range. max The maximum value of the range.
Returns: true
if the value is within the
specified range.
Parameters: value The value validation is being performed on. max The maximum value.
Returns: true
if the value is less than
or equal to the maximum.
Parameters: value The value validation is being performed on. max The maximum value.
Returns: true
if the value is less than
or equal to the maximum.
Parameters: value The value validation is being performed on. min The minimum value.
Returns: true
if the value is greater than
or equal to the minimum.
Parameters: value The value validation is being performed on. min The minimum value.
Returns: true
if the value is greater than
or equal to the minimum.
