Interface BeanValidator

public interface BeanValidator

Interface for the Install4JBeanInfo.ATTRIBUTE_BEAN_VALIDATOR value of a bean descriptor. With a bean validator you can check at design-time if the values of the bean properties are valid and notify the user if this is not the case.

The Install4JBeanInfo class offers a number of convenience methods to help bean validators to quickly check common conditions. It is most convenient if you make the bean info implement the BeanValidator interface itself, in that case the convenience methods are directly accessible.
