Messaging::Dispatcher Class Reference
#include <dispatcher.h>
Detailed Description
A message Dispatcher is a specialization of a message Port. A message Dispatcher distributes all messages it receives to the attached Ports which are interested in this message id.

Dispatcher objects usually serve as front end message ports which hide a more complex message processing infrastructure underneath.

| void Messaging::Dispatcher::HandleMessage | ( | const Ptr< Messaging::Message > & | msg | ) | [virtual] |
handle a single message (distribute to ports which accept the message)
Handle a message. The message will only be distributed to ports which accept the message.
Reimplemented from Messaging::Port.
attach a message port
Attach a new message port.
- Parameters:
-
port pointer to a message port object
remove a message port
Remove a message port object.
- Parameters:
-
handler pointer to message port object to be removed
return true if a port exists
Return true if a port is already attached.
attach a message handler to the port
Attach a message handler to the port.
remove a message handler from the port
Remove a message handler from the port.
send a message to the port
Send a message to the port. This will immediately call the HandleMessage() method of all attached handlers. If the message has been handled by at least one of the handlers, the Handled() flag of the message will be set to true.
| int Core::RefCounted::GetRefCount | ( | ) | const [inline, inherited] |
get the current refcount
Return the current refcount of the object.
| void Core::RefCounted::AddRef | ( | ) | [inline, inherited] |
increment refcount by one
Increment the refcount of the object.
| void Core::RefCounted::Release | ( | ) | [inline, inherited] |
decrement refcount and destroy object if refcount is zero
Decrement the refcount and destroy object if refcount is zero.
| const Util::String & Core::RefCounted::GetClassName | ( | ) | const [inline, inherited] |
get the class name
Get the class name of the object.
| Util::FourCC Core::RefCounted::GetClassFourCC | ( | ) | const [inline, inherited] |
get the class FourCC code
Get the class FourCC of the object.
| void Core::RefCounted::DumpRefCountingLeaks | ( | ) | [static, inherited] |
dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)
This method should be called as the very last before an application exits.
