Annotation Type Mod10Check

@Documented
 @Constraint(validatedBy={})
 @Target(value={METHOD,FIELD,ANNOTATION_TYPE,CONSTRUCTOR,PARAMETER,TYPE_USE})
 @Retention(value=RUNTIME)
 @Repeatable(value=Mod10Check.List.class)
public @interface Mod10Check

@Modulo 10 check constraint.

Allows to validate that a series of digits pass the Mod10 checksum algorithm. The classic Mod10 is calculated by summing up the digits, with every odd digit (from right to left) value multiplied by a multiplier. As example ISBN-13 is Modulo 10 checksum with multiplier = 3.

There are known cases of codes using multipliers for both even and odd digits; To support this kind of implementations the Mod10 constraint uses the weight option, which has the same effect as the multiplier but for even numbers.

The supported type is CharSequence. null is considered valid.

Element Detail

message

public abstract String message

Default:

"{org.hibernate.validator.constraints.Mod10Check.message}"

groups

public abstract Class<?>[] groups

Default:

{}

payload

public abstract Class<? extends Payload>[] payload

Default:

{}

multiplier

public abstract int multiplier

Returns:

The multiplier to be used for odd digits when calculating the Mod10 checksum.

Default:

3

weight

public abstract int weight

Returns:

The weight to be used for even digits when calculating the Mod10 checksum.

Default:

1

startIndex

public abstract int startIndex

Returns:

the start index (inclusive) for calculating the checksum. If not specified 0 is assumed.

Default:

0

endIndex

public abstract int endIndex

Returns:

the end index (inclusive) for calculating the checksum. If not specified the whole value is considered.

Default:

2147483647

checkDigitIndex

public abstract int checkDigitIndex

Returns:

The index of the check digit in the input. Per default it is assumed that the check digit is the last digit of the specified range. If set, the digit at the specified index is used. If set the following must hold true:
checkDigitIndex > 0 && (checkDigitIndex < startIndex || checkDigitIndex >= endIndex.

Default:

-1

ignoreNonDigitCharacters

public abstract boolean ignoreNonDigitCharacters

Returns:

Whether non-digit characters in the validated input should be ignored (true) or result in a validation error (false).

Default:

true
