    getBytes getDigest getEvents

    Methods

    • Get the serialized bytes of the signable object. Serialized bytes can be used to recreate the object using methods on Gateway.

      Returns Uint8Array

    • Get the digest of the signable object. This is used to generate a digital signature.

      Returns Uint8Array

    • Get chaincode events emitted by transaction functions of a specific chaincode.

      Parameters

      Returns Promise<CloseableAsyncIterable<ChaincodeEvent>>

      Chaincode events. The iterator should be closed after use to complete the eventing session.

      GatewayError Thrown by the iterator if the gRPC service invocation fails.

      const events = await request.getEvents();
      try {
          for await (const event of events) {
              // Process event
          }
      } finally {
          events.close();
      }
