> When using *avrogen* for generating C# models from a schemafile, the
> *--namespace* option doesn't behave as expected, if the model refers to other
> types (currently only tested with enums).
> When running
> {code:java}
> avrogen -s file.avsc . --namespace my.avro.ns:my.csharp.ns
> {code}
> the actual namespace of the generated C# files is changed to *my.csharp.ns*,
> but any references between the models are not updated with the correct
> namespace.
>
> Given a schemafile containing:
> {code:json}
> {
> "type" : "record",
> "name" : "TestModel",
> "namespace" : "my.avro.ns",
> "fields" : [ {
> "name" : "eventType",
> "type" : {
> "type" : "enum",
> "name" : "EventType",
> "symbols" : [ "CREATE", "UPDATE", "DELETE" ]
> }
> } ]
> }
> {code}
> And running
> {code:java}
> avrogen -s models.avsc . --namespace my.avro.ns:my.csharp.ns
> {code}
>
> Will produce the following *EventType.cs*
> {code:c#}
> namespace my.csharp.ns
> {
> using System;
> using System.Collections.Generic;
> using System.Text;
> using Avro;
> using Avro.Specific;
>
> public enum EventType
> {
> CREATE,
> UPDATE,
> DELETE,
> }
> }
> {code}
>
> and the following *TestModel.cs*
> {code:c#}
> namespace my.csharp.ns
> {
> using System;
> using System.Collections.Generic;
> using System.Text;
> using Avro;
> using Avro.Specific;
>
> public partial class TestModel : ISpecificRecord
> {
> public static Schema _SCHEMA =
> Avro.Schema.Parse("{\"type\":\"record\",\"name\":\"TestModel\",\"namespace\":\"my.avro.ns\",\"fields\":[{\"name\":\"e"
> +
>
> "ventType\",\"type\":{\"type\":\"enum\",\"name\":\"EventType\",\"namespace\":\"my.avro.ns\",\"sym"
> +
>
> "bols\":[\"CREATE\",\"UPDATE\",\"DELETE\"]}}]}");
> private my.avro.ns.EventType _eventType;
> // More generated code
> }
> }
> {code}
> Notice how the namespace is set correctly to *my.csharp.ns* in both files,
> but the namespace of the referenced *EventType* in *TestModel.cs* is
> incorrect.
>
> Example of expected output (*TestModel.cs*):
> {code:c#}
> namespace my.csharp.ns
> {
> using System;
> using System.Collections.Generic;
> using System.Text;
> using Avro;
> using Avro.Specific;
>
> public partial class TestModel : ISpecificRecord
> {
> public static Schema _SCHEMA =
> Avro.Schema.Parse("{\"type\":\"record\",\"name\":\"TestModel\",\"namespace\":\"my.avro.ns\",\"fields\":[{\"name\":\"e"
> +
>
> "ventType\",\"type\":{\"type\":\"enum\",\"name\":\"EventType\",\"namespace\":\"my.avro.ns\",\"sym"
> +
>
> "bols\":[\"CREATE\",\"UPDATE\",\"DELETE\"]}}]}");
> private my.csharp.ns.EventType _eventType;
> // More generated code
> }
> }
> {code}
