> Although avro can successfully parse schema text that contains a "doc" on a
> Schema.Field, when a Schema containing a field doc is serialized (via
> Schema.toString()) the doc does not get written.
> The following JUnit test case demonstrates this problem:
> {code:title=TestAvroFieldDocSerialization.java|borderStyle=solid}
> import junit.framework.TestCase;
> import org.apache.avro.Schema;
> public class TestAvroFieldDocSerialization extends TestCase {
> public void testAvroFieldDocSerialization() {
> String schemaStr =
> "{"+
> " \"name\": \"Rec\","+
> " \"type\": \"record\","+
> " \"fields\" : ["+
> " {\"name\": \"f\", \"type\": \"int\",
> \"doc\": \"test\"}"+
> " ]"+
> "}";
> Schema schema = Schema.parse(schemaStr);
> verifyFieldDoc(schema);
> schemaStr = schema.toString();
> schema = Schema.parse(schemaStr);
> verifyFieldDoc(schema);
> }
> private void verifyFieldDoc(Schema schema) {
> Schema.Field field = schema.getField("f");
> assertEquals("test", field.doc());
> }
> }
> {code}
> Note that the first call to verifyFieldDoc() succeeds, while the second one
> fails. They should both succeed (in my opinion).
