interceptDispatch

public Message interceptDispatch(Message message,

Intercepts the publication of a message. Implementers can use this to modify the contents of a message or block the publication altogether.

Return null or throw an exception to prevent publication of the message.

Specified by:

interceptDispatch in interface DispatchInterceptor

modifySerializedMessage

public SerializedMessage modifySerializedMessage(SerializedMessage serializedMessage,
 Message message,
 MessageType messageType)

Description copied from interface: DispatchInterceptor

Enables modification of the SerializedMessage before it is published.

This method is typically invoked by message gateways right before publication of a message (so after DispatchInterceptor.interceptDispatch(io.fluxcapacitor.javaclient.common.Message, io.fluxcapacitor.common.MessageType) is invoked).

Although message publication is stopped when null is returned or an exception is thrown, it is preferable to use DispatchInterceptor.interceptDispatch(io.fluxcapacitor.javaclient.common.Message, io.fluxcapacitor.common.MessageType) for that.
