new 3b06d5e629 AVRO-4202: Refer to fields for generated hashCode (#3547)
3b06d5e629 is described below
commit 3b06d5e629f4d91f6262c1f8175cee7a7b8d0983
Author: Steven Aerts <[email protected]>
AuthorDate: Fri Nov 14 18:11:56 2025 +0100
AVRO-4202: Refer to fields for generated hashCode (#3547)
The generated hashCode function has a local parameter called result.
To prevent this local variable to conflict with field which have the
same name, it has to refer to the fields with `this.<fieldName>` making
it unambiguous refer to fields and not local variables.
