...62   * <strong>Ignoring null fields in the recursive comparison</strong>63   * <p>64   * When an object is partially populated, it can still be interesting to see if its populated values are correct against a fully populated object.65   * <p>66   * This possible by calling {@link #ignoringActualNullFields()} before {@link #isEqualTo(Object) isEqualTo}67   * but bear in mind that <b>only actual null fields are ignored</b>, said otherwise the expected object null fields are used in the comparison.68   * <p>69   * <strong>Recursive comparison use of overridden {@code equals} methods</strong>70   * <p>71   * By default the recursive comparison is <b>not</b> applied on fields whose classes have overridden the {@code equals} method,72   * concretely it means {@code equals} is used to compare these fields instead of keeping on applying the recursive comparison.73   * The rationale is that if a class has redefined {@code equals} then it should be used to compare instances unless having a good reason.74   * <p>75   * It is possible though to change this behavior and force recursive comparison by calling any of these methods (but before calling {@code isEqualTo} otherwise this has no effect!):76   * <ol>77   * <li> {@link #ignoringOverriddenEqualsForTypes(Class...)} Any fields of these classes are compared recursively</li>78   * <li> {@link #ignoringOverriddenEqualsForFields(String...)} Any given fields are compared recursively</li>79   * <li> {@link #ignoringOverriddenEqualsForFieldsMatchingRegexes(String...)} Any fields matching one of these regexes are compared recursively</li>80   * <li> {@link #ignoringAllOverriddenEquals()} except for java types, all fields are compared field by field recursively.</li>81   * </ol>82   * <strong>Recursive comparison and cycles</strong>83   * <p>84   * The recursive comparison handles cycles.85   * <p>86   * <strong>Comparator used in the recursive comparison</strong>87   * <p>88   * By default {@code floats} are compared with a precision of 1.0E-6 and {@code doubles} with 1.0E-15.89   * <p>90   * You can specify a custom comparator or equals BiPredicate per (nested) fields or type with the methods below (but before calling {@code isEqualTo} otherwise this has no effect!):91   * <ol>92   * <li> {@link #withEqualsForType(BiPredicate, Class)} for a given type</li>93   * <li> {@link #withComparatorForType(Comparator, Class)} for a given type</li>94   * <li> {@link #withComparatorForFields(Comparator, String...) withComparatorForFields(Comparator, String...)} for one or multiple fields</li>95   * <li> {@link #withComparatorForFields(Comparator, String...) withComparatorForFields(Comparator, String...)} for one or multiple fields</li>96   * </ol>97   * <p>98   * Note that field comparators always take precedence over type comparators.99   * <p>100   * <strong>Example</strong>101   * <p>102   * Here is a basic example with a default {@link
