java.lang.Object

org.apache.beam.sdk.coders.Coder<PubsubMessage>

org.apache.beam.sdk.coders.CustomCoder<PubsubMessage>

org.apache.beam.sdk.io.gcp.pubsub.PubsubMessageWithAttributesCoder

All Implemented Interfaces:

Serializable

public class PubsubMessageWithAttributesCoder
extends CustomCoder<PubsubMessage>

A coder for PubsubMessage including attributes.

Maintainers should prefer PubsubMessageSchemaCoder over this coder when adding features to PubsubIO.

encode

public void encode(PubsubMessage value,
 OutputStream outStream)
            throws IOException

Description copied from class: Coder

Encodes the given value of type T onto the given output stream. Multiple elements can be encoded next to each other on the output stream, each coder should encode information to know how many bytes to read when decoding. A common approach is to prefix the encoding with the element's encoded length.

Specified by:

encode in class Coder<PubsubMessage>

Throws:

IOException - if writing to the OutputStream fails for some reason

encode

public void encode(PubsubMessage value,
 OutputStream outStream,
 Coder.Context context)
            throws IOException

Description copied from class: Coder

Encodes the given value of type T onto the given output stream in the given context.

Overrides:

encode in class Coder<PubsubMessage>

Throws:

IOException - if writing to the OutputStream fails for some reason

decode

public PubsubMessage decode(InputStream inStream)
                     throws IOException

Description copied from class: Coder

Decodes a value of type T from the given input stream in the given context. Returns the decoded value. Multiple elements can be encoded next to each other on the input stream, each coder should encode information to know how many bytes to read when decoding. A common approach is to prefix the encoding with the element's encoded length.

Specified by:

decode in class Coder<PubsubMessage>

Throws:

IOException - if reading from the InputStream fails for some reason

decode

public PubsubMessage decode(InputStream inStream,
