Class DoubleMinValidator<T>

java.lang.Object

io.jmix.ui.component.validation.AbstractValidator<T>

io.jmix.ui.component.validation.DoubleMinValidator<T>

Type Parameters:

T - Double and String that represents BigDouble value with current locale

All Implemented Interfaces:

Validator<T>, java.util.function.Consumer<T>

@Component(value="ui_DoubleMinValidator")
 @Scope(value="prototype")
public class DoubleMinValidator<T>
extends AbstractValidator<T>

Double validator checks that value must be greater than or equal to the specified minimum.

For error message it uses template string and it is possible to use '${value}' and '${min}' keys for formatted output.

In order to provide your own implementation globally, create a subclass and register it in configuration class, for example:

     @Bean("ui_DoubleMinValidator")
     @Scope(BeanDefinition.SCOPE_PROTOTYPE)
     @Primary
     protected DoubleMinValidator doubleMinValidator(Double min) {
          return new CustomDoubleMinValidator(min);
     }
