R - the type of response expectedpublic class ConvertingResponseMessage<R> extends Object implements QueryResponseMessage<R>
The conversion is generally used to accommodate response types that aren't compatible with serialization, such as
OptionalResponseType.
| Constructor and Description |
|---|
ConvertingResponseMessage(ResponseType<R> expectedResponseType,
QueryResponseMessage<?> responseMessage)
Initialize a response message, using
expectedResponseType to convert the payload from the responseMessage, if necessary. |
| Modifier and Type | Method and Description |
|---|---|
QueryResponseMessage<R> |
andMetaData(Map<String,?> additionalMetaData)
Returns a copy of this QueryResponseMessage with its MetaData merged with given
metaData. |
String |
getIdentifier()
Returns the identifier of this message.
|
MetaData |
getMetaData()
Returns the meta data for this event.
|
R |
getPayload()
Returns the payload of this Event.
|
Class<R> |
getPayloadType()
Returns the type of the payload.
|
boolean |
isExceptional()
Indicates whether the ResultMessage represents unsuccessful execution.
|
Optional<Throwable> |
optionalExceptionResult()
Returns the Exception in case of exceptional result message or an empty
Optional in case of successful
execution. |
<T> SerializedObject<T> |
serializeExceptionResult(Serializer serializer,
Class<T> expectedRepresentation)
Serializes the exception result.
|
<R1> SerializedObject<R1> |
serializeMetaData(Serializer serializer,
Class<R1> expectedRepresentation)
Serialize the meta data of this message to the
expectedRepresentation using given serializer. |
<S> SerializedObject<S> |
serializePayload(Serializer serializer,
Class<S> expectedRepresentation)
Serialize the payload of this message to the
expectedRepresentation using given serializer. |
QueryResponseMessage<R> |
withMetaData(Map<String,?> metaData)
Returns a copy of this QueryResponseMessage with the given
metaData. |
