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();
  }
}

After the quick-fix is applied:

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();.

Inspection options
