方法详细资料

extractAvroSpecificSchema

public static <T> org.apache.avro.Schema extractAvroSpecificSchema(Class<T> type,
                                                                   org.apache.avro.specific.SpecificData specificData)

Extracts an Avro Schema from a SpecificRecord. We do this either via SpecificData or by instantiating a record and extracting the schema from the instance.

getSpecificDataForClass

public static <T extends org.apache.avro.specific.SpecificData> org.apache.avro.specific.SpecificData getSpecificDataForClass(Class<T> type,
                                                                                                                              ClassLoader cl)

Creates a SpecificData object for a given class. Possibly uses the specific data from the generated class with logical conversions applied (avro >= 1.9.x).

Copied over from SpecificData#getForClass(Class<T> c) we do not use the method directly, because we want to be API backwards compatible with older Avro versions which did not have this method
