Class RegexpValidator

java.lang.Object

com.haulmont.cuba.gui.components.validation.AbstractValidator<java.lang.String>

com.haulmont.cuba.gui.components.validation.RegexpValidator

All Implemented Interfaces:

java.util.function.Consumer<java.lang.String>

@Scope(value="prototype")
 @Component(value="cuba_RegexpValidator")
public class RegexpValidator
extends AbstractValidator<java.lang.String>

Regexp validator checks that String value is matched with specified regular expression.

The regular expression follows the Java regular expression conventions.

For error message it uses Groovy string and it is possible to use '$value' key for formatted output.

In order to provide your own implementation globally, create a subclass and register it in web-spring.xml, for example:

     <bean id="cuba_RegexpValidator" class="com.haulmont.cuba.gui.components.validation.RegexpValidator" scope="prototype"/>
     

Use BeanLocator when creating the validator programmatically.
