Constant Field Values
public static boolean (java.lang.String value)
Checks if the field isn't null and length of the field is greater than zero not
including whitespace.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value,
java.lang.String regexp)
Checks if the value matches the regular expression.
- Parameters:
value - The value validation is being performed on.regexp - The regular expression.
public static boolean (java.lang.String value)
Checks if the value can safely be converted to a byte primitive.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value)
Checks if the value can safely be converted to a short primitive.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value)
Checks if the value can safely be converted to a int primitive.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value)
Checks if the value can safely be converted to a long primitive.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value)
Checks if the value can safely be converted to a float primitive.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value)
Checks if the value can safely be converted to a double primitive.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value,
java.util.Locale locale)
Checks if the field is a valid date. The Locale is
used with java.text.DateFormat . The setLenient method
is set to false for all.
- Parameters:
value - The value validation is being performed on.
public static boolean (java.lang.String value,
java.lang.String datePattern,
boolean strict)
Checks if the field is a valid date. The pattern is used with
java.text.SimpleDateFormat . If strict is true, then the
length will be checked so '2/12/1999' will not pass validation with
the format 'MM/dd/yyyy' because the month isn't two digits.
The setLenient method is set to false for all.
- Parameters:
value - The value validation is being performed on.datePattern - The pattern passed to SimpleDateFormat .strict - Whether or not to have an exact match of the datePattern.
public static boolean (int value,
int min,
int max)
Checks if a value is within a range (min & max specified
in the vars attribute).
- Parameters:
value - The value validation is being performed on.min - The minimum value of the range.max - The maximum value of the range.
public static boolean (float value,
float min,
float max)
Checks if a value is within a range (min & max specified
in the vars attribute).
- Parameters:
value - The value validation is being performed on.min - The minimum value of the range.max - The maximum value of the range.
public static boolean (short value,
short min,
short max)
Checks if a value is within a range (min & max specified
in the vars attribute).
- Parameters:
value - The value validation is being performed on.min - The minimum value of the range.max - The maximum value of the range.
public static boolean (double value,
double min,
double max)
Checks if a value is within a range (min & max specified
in the vars attribute).
- Parameters:
value - The value validation is being performed on.min - The minimum value of the range.max - The maximum value of the range.
