方法详细资料

forGeneric

public static AvroDeserializationSchema<org.apache.avro.generic.GenericRecord> forGeneric(org.apache.avro.Schema schema)

Creates AvroDeserializationSchema that produces GenericRecord using provided schema.

参数:

schema - schema of produced records

返回:

deserialized record in form of GenericRecord

forSpecific

public static <T extends org.apache.avro.specific.SpecificRecord> AvroDeserializationSchema<T> forSpecific(Class<T> tClass)

Creates AvroDeserializationSchema that produces classes that were generated from avro schema.

参数:

tClass - class of record to be produced

返回:

deserialized record

deserialize

public T deserialize(@Nullable
                     byte[] message)
