in repository https://gitbox.apache.org/repos/asf/sis.git
commit 4b389265a72ef36b9d97a13865a41664a9df3413
Author: Martin Desruisseaux <martin.desruisse...@geomatys.com>
AuthorDate: Sat Sep 21 12:08:52 2024 +0200
Simplify fetching `MethodHandle` by storing the linker as a
`NativeFunctions` field.
Make the method handles for `move` and `delete` operations optional.
