in repository https://gitbox.apache.org/repos/asf/sis.git
The following commit(s) were added to refs/heads/geoapi-4.0 by this push:
new 0ee27a9df1 Provide more context in the internal
`createMapProjection(…)` method. This is needed when the projection needs to
delegate to another method. This change replaces
`NormalizedProjection.delegate(…)`.
0ee27a9df1 is described below
commit 0ee27a9df15a5cdcd1e2afd46195770265bae9da
Author: Martin Desruisseaux <[email protected]>
AuthorDate: Wed Apr 24 13:06:36 2024 +0200
Provide more context in the internal `createMapProjection(…)` method.
This is needed when the projection needs to delegate to another method.
This change replaces `NormalizedProjection.delegate(…)`.
