Examples of org.apache.avro.Schema$Parser

org.eclipse.orion.server.cf.manifest.v2.Parser
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.

    for (ColumnInfo column : columnInfo) {


      Schema.Field columnField = getColumnField(column);
      fields.add(columnField);
    }
    Schema recordSchema = Schema.createRecord("hihoValue", null, null,
        false);
    recordSchema.setFields(fields);
    return recordSchema;
