Chained method calls

Reports method calls whose target is another method call. The quick-fix suggests to introduce a local variable.

Example:

class X { int foo(File f) { return f.getName().length(); } }
class X { int foo(File f) { final String name = f.getName(); return name.length(); } }

Use the inspection options to toggle warnings for the following cases:

  • chained method calls in field initializers, for instance, private final int i = new Random().nextInt();

  • chained method calls operating on the same type, for instance, new StringBuilder().append("x: ").append(new X()).append("y: ").append(new Y()).toString();.
