CMessage

Tue, 14 Oct 2025 00:00:00 +0000

CMessage is simply a container for the classes CEnvelope and CRecord.

Constructors

There are two constructors for the class. The first one takes over the given components:

public CMessage(@NotNull final CEnvelope aEnvelope,
                @NotNull final CRecord aRecord);

The second constructor takes a template and is actually a copy constructor:

public CMessage(@NotNull final CMessage aTemplate);

Stream

Furthermore, there is a static method for reading the message from a DataInput stream:

public static CMessage fromStream(@NotNull final DataInput aStream) throws IOException;

Accordingly, there is also a method for writing to a DataOutput stream:

IMessageSender

The message sender is the service that can send messages. There are also methods for sending messages in targets, but these also use the message sender internally.

The message sender is available as a service via the service registry.

final IMessageSender messageSender = CServiceRegistry.getInstance()
                                                     .getService(IMessageSender.class);

Send messages

The methods for sending messages are always executed in pairs. While one method receives a complete message, the second method always receives the components of the message.

void send(@NotNull CMessage aMsg) throws CException;
void send(@NotNull CEnvelope aEnvelope,
          @NotNull CRecord aRecord) throws CException;
