Method Detail

• equals

   static boolean equals(@Nullable() Object a, @Nullable() Object b)

  Returns {@code true} if the arguments are equal to each otherand {@code false} otherwise.

  Consequently, if both arguments are {@code null}, {@code true} is returned and if exactly one argument is {@code null}, {@code * false} is returned. Otherwise, equality is determined by usingthe equals method of the firstargument.

  Parameters:

  a - an object

  b - an object to be compared with {@code a} for equality

• hashCode

   static int hashCode(@Nullable() Object o)

  Returns the hash code of a non-{@code null} argument and 0 for a {@code null} argument.

  Parameters:

  o - an object

• hash

   static int hash(@Nullable() Array<Object> values)

  Generates a hash code for a sequence of input values. The hash code is generated as if allthe input values were placed into an array, and that array were hashed by calling hashCode.

  This method is useful for implementing hashCode on objects containingmultiple fields. For example, if an object that has three fields, {@code x}, {@code y}, and {@code z}, one could write:

  @Override public int hashCode() {
      return ObjectsCompat.hash(x, y, z);
  }
  

  Warning: When a single object reference is supplied, the returned value does not equal thehash code of that object reference. This value can be computed by calling hashCode.

  Parameters:

  values - the values to be hashed

• toString

  @Nullable() static String toString(@Nullable() Object o, @Nullable() String nullDefault)

  Returns the result of calling {@code toString} on the first argument if the first argumentis not {@code null} and returns the second argument otherwise.

  Parameters:

  o - an object

  nullDefault - string to return if the first argument is {@code null}
