[lucy-issues] [jira] [Created] (CLOWNFISH-57) Map clownfish.Obj to Go empty
interface
Marvin Humphrey created CLOWNFISH-57:
----------------------------------------
Summary: Map clownfish.Obj to Go empty interface
Key: CLOWNFISH-57
URL: https://issues.apache.org/jira/browse/CLOWNFISH-57
Project: Apache Lucy-Clownfish
Issue Type: Improvement
Components: Go
Reporter: Marvin Humphrey
Assignee: Marvin Humphrey
Fix For: 0.5.0
Autogenerated bindings for Clownfish subroutines which accept or return
clownfish Obj should be mapped to Go's "empty interface" type, `interface{}`.
This sacrifices some type safety, but it is the only way to achieve certain
desirable effects. For example, it should be possible for Vector's Push()
method to take a Go string, instead of requiring the user to perform a manual
conversion to a Clownfish object. Similarly, Vector's Pop() should be able to
return a Go string.
Functions which need to return an actual clownfish Obj wrapped in a Go struct
will need to have hand-coded bindings, but there are fewer of those so
converting Obj by default is the better choice.
