Method Detail

addValidator

protected void addValidator(String attributeName,
                            Validator validator)

Adds a validator whose validation failed.

Parameters:

attributeName - name of attribute for which validation failed.

validator - validator.

setLocale

public void setLocale(Locale locale)

Sets a locale on this instance. All messages returned from get(Object) methods will be returned according to rules of Java Resource Bundles.

Parameters:

locale - locale instance to configure this object.

get

public String get(Object attributeName)

Provides a message from a resource bundle activejdbc_messages. If an there was no validation error generated for the requested attribute, returns null.

Specified by:

get in interface Map<String,String>

Parameters:

attributeName - name of attribute in error.

Returns:

a message from a resource bundle activejdbc_messages as configured in a corresponding validator. If an there was no validation error generated for the requested attribute, returns null.

get

public String get(String attributeName,
                  Object... params)

Provides a message from the resource bundle activejdbc_messages which is merged with parameters. This methods expects the message in the resource bundle to be parametrized. This message is configured for a validator using a Fluent Interface when declaring a validator:

        public class Temperature extends Model {
            static{
                validateRange("temp", 0, 100).message("temperature cannot be less than {0} or more than {1}");
            }
        }
 

Parameters:

attributeName - name of attribute in error.

params - list of parameters for a message. The order of parameters in this list will correspond to the numeric order in the parameters listed in the message and has nothing to do with a physical order. This means that the 0th parameter in the list will correspond to {0}, 1st to {1} and so on.

Returns:

a message from the resource bundle activejdbc_messages with default locale, which is merged with parameters.
