|

* It should be easy to add char[] and CharSequence ByteGetter instances, |
63 | 61 |

65 | 63 |
* I did not implement real unsigned 32-bit integers or emulate them with long, |
66 | 64 |
* as both java Arrays and Strings currently can have only 2^31-1 elements |
67 | 65 |
* (bytes), so we cannot even get or build Geometries with more than approx. |
68 | 66 |
* 2^28 coordinates (8 bytes each). |
