Class ChainCodec

java.lang.Object
io.temporal.payload.codec.ChainCodec
All Implemented Interfaces:
PayloadCodec
public class ChainCodec extends Object implements PayloadCodec
Performs encoding/decoding on the payloads via the given codecs. When encoding, the codecs are applied last to first meaning the earlier encoders wrap the later ones. When decoding, the codecs are applied first to last to reverse the effect.

    • ChainCodec

      public ChainCodec(Collection<PayloadCodec> codecs)
      Parameters:
      codecs - to apply. When encoding, the codecs are applied last to first meaning the earlier encoders wrap the later ones. When decoding, the codecs are applied first to last to reverse the effect

  • Method Details

    • encode

      @Nonnull public List<io.temporal.api.common.v1.Payload> encode(@Nonnull List<io.temporal.api.common.v1.Payload> payloads)
      Specified by:
      encode in interface PayloadCodec

    • decode

      @Nonnull public List<io.temporal.api.common.v1.Payload> decode(@Nonnull List<io.temporal.api.common.v1.Payload> payloads)
      Specified by:
      decode in interface PayloadCodec

    • withContext

      @Nonnull public PayloadCodec withContext(@Nonnull SerializationContext context)
      Description copied from interface: PayloadCodec
      A correct implementation of this interface should have a fully functional "contextless" implementation. Temporal SDK will call this method when a knowledge of the context exists, but DataConverter can be used directly by user code and sometimes SDK itself without any context.

      Note: this method is expected to be cheap and fast. Temporal SDK doesn't always cache the instances and may be calling this method very often. Users are responsible to make sure that this method doesn't recreate expensive objects like Jackson's ObjectMapper on every call.

      Specified by:
      withContext in interface PayloadCodec
      Parameters:
      context - provides information to the data converter about the abstraction the data belongs to
      Returns:
      an instance of DataConverter that may use the provided context for serialization
