> SC: a property defined by an extension method of List is read from each
> element of the list
> -------------------------------------------------------------------------------------------
>
> Key: GROOVY-12534
> URL: https://issues.apache.org/jira/browse/GROOVY-12534
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Assignee: Daniel Sun
> Priority: Major
> Fix For: 7.0.0-alpha-1, 6.0.1
>
>
> Under {{@CompileStatic}}, a property whose getter is an extension method of
> {{List}}, or of a class that implements {{List}}, is compiled as a property
> of the list's elements: the getter is called once for each element, with the
> element cast to the extension's receiver type. With this extension module:
> {code:java}
> package demo;
> import java.util.List;
> public class ListExtension {
> public static String getJoined(List<String> self) { return
> String.join(",", self); }
> }
> {code}
> {code:groovy}
> @groovy.transform.CompileStatic
> class C {
> def test(List<String> words) { words.joined }
> }
> new C().test(['x', 'y']) // GroovyCastException: Cannot cast object 'x' with
> class 'java.lang.String' to class 'java.util.List'
> {code}
> {{words.getJoined()}} returns 'x,y' in every mode, and dynamic Groovy and
> {{@TypeChecked}} return 'x,y' for {{words.joined}} too. On an empty list,
> {{words.joined}} evaluates to {{[]}} instead of an empty string.
> {{StaticCompilationVisitor.existsProperty}} marks the property expression
> spread-safe when the getter's declaring class implements {{List}} but does
> not declare the getter, which is meant for a property of the element type.
> The declaring class of an extension method is its receiver type, which never
> declares it. Extension getters declared for {{Collection}} or {{Iterable}},
> such as {{getIndices}} and {{isSorted}}, are not affected.
> {{DefaultGroovyMethodsSTCTest.testPropertySemantics2}}, which
> {{StaticCompileDGMTest}} also runs, keeps the property forms of
> {{getSequence(List)}} and {{getString(List)}} from {{TestStringExtension}}
> commented out. Seen in 4.0.33, 5.0.8, 6.0.0 and master.
> Expected: the property calls the extension getter on the list, as in dynamic
> Groovy and {{@TypeChecked}}.
