Subject [jira] [Updated] (AVRO-1146) Can't use ReflectData to get schema when the type has a BigDecimal field
Date Sat, 01 Sep 2012 05:46:07 GMT

     [ https://issues.apache.org/jira/browse/AVRO-1146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Alexandre Normand updated AVRO-1146:

    Labels: newbie  (was: )
    Status: Patch Available  (was: Open)

One problem is that all subclasses of java.lang.Number are considered primitives in ReflectData.createSchema.
Since BigDecimal and BigInteger are not actual primitives, I made the check more precise to
actually check for all 9 primitive classes. 
I've added a map of wrapper classes to primitive types to make the code cleaner but I'm not
sure this fits the coding style. It could very well just be a long series of 
if (c == Void.class || c == Integer.class || ...

I've made it so that BigDecimal and BigInteger are handled as Stringable types, which they

I've also added a test for this in TestReflect.

I'm trying to get the Schema for has a field of type BigDecimal. Because BigDecimal extends
java.lang.Number, we try to create a primitive schema for it but fail doing so with the following
