Return of 'this'

Reports methods returning this.

While such a return is valid, it is rarely necessary, and usually indicates that the method is intended to be used as part of a chain of similar method calls (for example, buffer.append("foo").append("bar").append("baz")). Such chains are frowned upon by many coding standards.

Example:

  public Builder append(String str) {
    // [...]
    return this;
  }
