Method Detail

isBlankOrNull

public static boolean isBlankOrNull(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.

matchRegexp

public static boolean matchRegexp(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.

isByte

public static boolean isByte(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.

isShort

public static boolean isShort(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.

isInt

public static boolean isInt(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.

isLong

public static boolean isLong(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.

isFloat

public static boolean isFloat(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.

isDouble

public static boolean isDouble(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.

isDate

public static boolean isDate(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.

locale - The locale to use for the date format, defaults to the default system default if null.

isDate

public static boolean isDate(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.
