Subject Parsing Nested Schemas in Avro C++
Date Tue, 17 Dec 2013 10:17:00 GMT

Is there a C++ equivalent of the following Java functionality?

/    public static class Schema.Parser extends Object

    A parser for JSON-format schemas. Each named schema parsed with a parser
is added to the names known to the parser so that subsequently parsed
schemas may refer to it by name.
We have used this class from the Avro Java API to obtain a parser, and
pre-parse complex object type schemas which are referred to in later
schemas. E.g. we have parsed a record schema called "location", and referred
to this subsequently by name in another (higher level) schema.

Now trying to do the equivalent with the C++ API, and so far I have not
found this functionality. 

I can do (from the documentation):

/    // My schema is stored in a file called “example”
    std::ifstream in(“example”);

    avro::ValidSchema mySchema;
    avro::compileJsonSchema(in, mySchema);
But this appears to only parse a single schema. It doesn't return a handle
to the parser which can be used to parse further schemas. If I try putting
multiple schemas in the input stream, it only parses the first one.
