Thiruvalluvan M. G. updated AVRO-628:
-------------------------------------
    Component/s: c

> Unions have no getter function (avro_union_get)
> -----------------------------------------------
>
>                 Key: AVRO-628
>                 URL: https://issues.apache.org/jira/browse/AVRO-628
>             Project: Apache Avro
>          Issue Type: Improvement
>          Components: c
>            Reporter: Gavin M. Roy
>            Priority: Major
>
> The union data type has no getter function and as such, the only way to get to the data in the union is to create a struct
> {code}typedef struct avro_union_datum_t {
> 	struct avro_obj_t obj;
> 	int64_t discriminant;
> 	avro_datum_t value;
> } avro_union_datum_t;{code}
> in your own include or code as the struct for this is in datum.h which is not installed with the library.  In addition, there is a type warning when trying to use avro_record_get using the avro_union_datum_t.
> Ideally there would be a getter that exposes the datum in the union.
