Class DOOV

java.lang.Object

io.doov.core.dsl.DOOV

public class DOOV
extends java.lang.Object

Entry point of the DSL.

All validation rules will start with the when(StepCondition) method. Then you can create a step condition either by referencing a FieldInfo that you generated (in the example below it's userEmail) or by using a composition method like matchAll(StepCondition...).

 DOOV.when(userEmail().matches("...")).validate();
