groovy.transform.builder.SimpleStrategy

All Implemented Interfaces:
  `BuilderASTTransformation.BuilderStrategy`

public class SimpleStrategy extends BuilderASTTransformation.AbstractBuilderStrategy
This strategy is used with the `Builder` AST transform to modify your Groovy objects so that the setter methods for properties return the original object, thus allowing chained usage of the setters. You use it as follows:

     import groovy.transform.builder.*

     @Builder(builderStrategy=SimpleStrategy)
     class Person {
         String firstName
         String lastName
         int age
     }
     def person = new Person().setFirstName("Robert").setLastName("Lewandowski").setAge(21)
     assert person.firstName == "Robert"
     assert person.lastName == "Lewandowski"
     assert person.age == 21

The `prefix` annotation attribute can be used to create setters with a different naming convention, e.g. with the prefix set to the empty String, you would use your setters as follows:

     def p1 = new Person().firstName("Robert").lastName("Lewandowski").age(21)

or using a prefix of 'with':

     def p2 = new Person().withFirstName("Robert").withLastName("Lewandowski").withAge(21)

When using the default prefix of "set", Groovy's normal setters will be replaced by the chained versions. When using a custom prefix, Groovy's unchained setters will still be available for use in the normal unchained fashion. The 'useSetters' annotation attribute can be used for writable properties as per the `Builder` transform documentation. The other annotation attributes for the `@Builder` transform for configuring the building process aren't applicable for this strategy.
