Method Detail

isNullable

boolean isNullable(V valueMap,
                   K key)

Parameters:

valueMap - the value map

key - the key

Returns:

true if this value is allowed to be null in the given value map

isValid

boolean isValid(V valueMap)

Parameters:

valueMap - the value map

Returns:

true if the given value map contains only valid values

validate

void validate(V valueMap)
       throws ValidationException

Checks if the values in the given value map are valid

Parameters:

valueMap - the value map

Throws:

ValidationException - in case of an invalid value

validate

void validate(V valueMap,
              K key)
       throws ValidationException

Checks if the value associated with the give key is valid, throws a ValidationException if not

Parameters:

valueMap - the value map to validate

key - the key the value is associated with

Throws:

ValidationException - if the given value is not valid for the given key

revalidate

void revalidate()

Notifies all re-validation listeners that a re-validation is called for, for example due to modified validation settings
