The range of the elements of the $array is from the $offset to the position proceeded by the $length.

If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.

Exceptions:

The $array must be defined. Otherwize an exception is thrown.

The $offset must be greater than or equal to 0. Otherwize an exception is thrown.

The $offset + the $length must be less than or equal to the length of the $array. Otherwize an exception is thrown.

=head2 memset_object

  static method memset_object : void ($array : object[], $element : object, $offset = 0 : int, $length = -1 : int);

The alias for the following code using L</"memset_object">.

  &memset_object($dest, $element, $dest_offset, $length);

=head2 new_proto

  static method new_proto : object[] ($proto_array : object[], $length : int);

Create a new object array as the same type as the $proto_array with the $length.

Exceptions:
