Package groovy.transform.builder

## Class SimpleStrategy

- java.lang.Object
- - org.codehaus.groovy.transform.BuilderASTTransformation.AbstractBuilderStrategy
  - - 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.
