Method Detail

encode

public void encode(BeamAggregationTransforms.AggregationAccumulator value,
                   java.io.OutputStream outStream)
            throws CoderException,
                   java.io.IOException

Description copied from class: Coder

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

Specified by:

encode in class Coder<BeamAggregationTransforms.AggregationAccumulator>

Throws:

CoderException - if the value could not be encoded for some reason

java.io.IOException - if writing to the OutputStream fails for some reason

decode

Description copied from class: Coder

Decodes a value of type T from the given input stream in the given context. Returns the decoded value.

Specified by:

decode in class Coder<BeamAggregationTransforms.AggregationAccumulator>

Throws:

CoderException - if the value could not be decoded for some reason

java.io.IOException - if reading from the InputStream fails for some reason
