Usage
package test;
import com.google.auto.value.AutoValue;
import cz.jcode.auto.value.step.builder.AutoValueStepBuilder;
import javax.annotation.Nullable;
@AutoValue
@AutoValueStepBuilder
public abstract class Value {
public abstract String required1();
public abstract String required2();
public abstract String required3();
@Nullable
public abstract String optional1();
@Nullable
public abstract String optional2();
public static AutoValue_Value.Required1Step step() {
return AutoValue_Value.step();
}
public static AutoValue_Value.Required1LazyStep lazyStep() {
return AutoValue_Value.lazyStep();
}
}
Simple Example
package test;
public class Main {
public static void main(String[] args) {
Value.step()
.required1("string")
.required2("string")
.required3("string")
.optional()
.optional1("optional")
.optional2(null)
.build();
Value.lazyStep()
.required1(() -> "string")
.required2(() -> "string")
.required3(() -> "string")
.optional()
.optional1(() -> "optional")
.optional2(() -> null)
.build();
}
