Paul King closed GROOVY-7956. ----------------------------- > Provide an AST transformation which improves named parameter support > -------------------------------------------------------------------- > > Key: GROOVY-7956 > URL: https://issues.apache.org/jira/browse/GROOVY-7956 > Project: Groovy > Issue Type: New Feature > Components: GEP > Reporter: Graeme Rocher > Assignee: Paul King > Priority: Major > Fix For: 2.5.0-beta-3 > > > In order to aid static compilation for builders we have {{@DelegatesTo}} > which allows statically compiled code to know what the delegate of a closure > is. > This proposal is to allow {{@DelegatesTo}} on {{Map}} types such that IDEs > and the static compiler can resolve the target type the named arguments are > to be used on. > For example: > {code} > class Farm { > void animal(@DelegatesTo(Animal) Map arguments, > @DelegatesTo(AnimalBuilder) Closure callable) { > def animal = new Animal(arguments) > // handle closure > } > } > class Animal { String name } > {code} > The following code would then fail to compile : > {code} > def farm = new Farm() > // compilation failure, no name property on Animal > farm.animal(nam: "Dog") { > } > {code} > It would then be down to IDEs to also provide support for code completion etc. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
