- - ### Element Detail

    - #### knownImmutableClasses

          Class[] knownImmutableClasses

      Allows you to provide `@Immutable` with a list of classes which are deemed immutable. By supplying a class in this list, you are vouching for its immutability and `@Immutable` will do no further checks. Example:

           import groovy.transform.*
           @Immutable(knownImmutableClasses = [Address])
           class Person {
               String first, last
               Address address
           }

           @TupleConstructor
           class Address {
               final String street
           }

      Default:
        {}

  - - #### knownImmutables

          String[] knownImmutables

      Allows you to provide `@Immutable` with a list of property names which are deemed immutable. By supplying a property's name in this list, you are vouching for its immutability and `@Immutable` will do no further checks. Example:

           @groovy.transform.Immutable(knownImmutables = ['address'])
           class Person {
               String first, last
               Address address
           }
           ...

      Default:
        {}
