isValid

public boolean isValid(V valueMap)

Specified by:

isValid in interface ValueMap.Validator<K,V extends ValueMap<K,?>>

Parameters:

valueMap - the value map

Returns:

true if the given value map contains only valid values

validate

public void validate(V valueMap)
              throws ValidationException

Checks if the values in the given value map are valid

Specified by:

validate in interface ValueMap.Validator<K,V extends ValueMap<K,?>>

Parameters:

valueMap - the value map

Throws:

ValidationException - in case of an invalid value

validate

public void validate(V valueMap,
                     K key)
              throws ValidationException

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

Specified by:

validate in interface ValueMap.Validator<K,V extends ValueMap<K,?>>

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

public final void revalidate()

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

Specified by:
