🚀 New and noteworthy

Collections exposed as XPath attributes

Up to now, all AST node getters would be exposed to XPath, as long as the return type was a primitive (boxed or unboxed), String or Enum. That meant that collections, even of these basic types, were not exposed, so for instance accessing Apex's ASTUserClass.getInterfaceNames() to list the interfaces implemented by a class was impossible from XPath, and would require writing a Java rule to check it.

Since this release, PMD will also expose any getter returning a collection of any supported type as a sequence through an XPath attribute. They would require to use apropriate XQuery functions to manipulate the sequence. So for instance, to detect any given ASTUserClass in Apex that implements Queueable, it is now possible to write:

/UserClass[@InterfaceNames = 'Queueable']
