    • decode

      public T decode(ByteBuffer buffer)

    • decode

      public T decode(ByteBuffer buffer, byte[] schemaVersion)

    • decode

      public T decode(io.netty.buffer.ByteBuf byteBuf)
      Description copied from class: AbstractSchema
      Decode a byteBuf into an object using the schema definition and deserializer implementation

      Do not modify reader/writer index of ByteBuf so, it can be reused to access correct data.

      Specified by:
      decode in class AbstractSchema<T>
      Parameters:
      byteBuf - the byte buffer to decode
      Returns:
      the deserialized object

    • decode

      public T decode(io.netty.buffer.ByteBuf byteBuf, byte[] schemaVersion)
      Description copied from class: AbstractSchema
      Decode a byteBuf into an object using a given version.
      Overrides:
      decode in class AbstractSchema<T>
      Parameters:
      byteBuf - the byte array to decode
      schemaVersion - the schema version to decode the object. null indicates using latest version.
      Returns:
      the deserialized object

    • getSchemaInfo

      public SchemaInfo getSchemaInfo()

    • setSchemaInfoProvider

      public void setSchemaInfoProvider(SchemaInfoProvider schemaInfoProvider)

    • atSchemaVersion

      public Schema<T> atSchemaVersion(byte[] schemaVersion) throws SchemaSerializationException
      Description copied from class: AbstractSchema
      Return an instance of this schema at the given version.
      Overrides:
      atSchemaVersion in class AbstractSchema<T>
      Parameters:
      schemaVersion - the version
      Returns:
      the schema at that specific version
      Throws:
      SchemaSerializationException - in case of unknown schema version
