Method Details

getEncodingType

public String getEncodingType()

Description copied from interface: PayloadConverter

Each PayloadConverter has an Encoding Type that it handles. Each PayloadConverter should add the information about its Encoding Type into the Payload it produces inside PayloadConverter.toData(Object) by associating it with the EncodingKeys.METADATA_ENCODING_KEY key attached to the Payload's Metadata using Payload.Builder.putMetadata(String, ByteString).

Specified by:

getEncodingType in interface PayloadConverter

Returns:

encoding type that this converter handles.

toData

public Optional<io.temporal.api.common.v1.Payload> toData(Object value)
                                                   throws DataConverterException
