AsyncGraphics::AsyncGraphicsInterface Class Reference
#include <asyncgraphicsinterface.h>
Detailed Description
Implements the asynchronous interface to the Graphics subsystem. Usually the application doesn't call methods on the AsyncGraphicsInterface directly, but instead uses one of the AsyncGraphics proxy objects to communicate with the graphics thread.(C) 2007 Radon Labs GmbH

Member Function Documentation
attach a handler to the port (call before open!)
Called by OnCreateHandlers() method of subclass to attach a handler to the port.
| void Messaging::AsyncPort::Close | ( | ) | [virtual, inherited] |
close the async port
Closes the async port.
send an asynchronous message to the port
Handle an asynchronous message and return immediately. If the caller expects any results from the message he can poll with the AsyncPort::Peek() method, or he may wait for the message to be handled with the AsyncPort::Wait() method.
send a message and wait for completion
Send an asynchronous message and wait until the message has been handled.
wait for a message to be handled
This method will wait until a message has been handled. If the caller expects any return arguments from the message handling it can use this method to wait for the results.
peek a message whether it has been handled
This method peeks whether a message has already been handled. If the caller expects any return arguments from the message handling it can use this message to check whether the results are ready using this non-blocking method. The caller can also wait for the results to become ready using the Wait() method.
cancel a pending message
This method will cancel a pending message.
| void Messaging::AsyncPort::Flush | ( | ) | [inherited] |
wait until all pending messages have been handled
This method will wait until ALL pending messages have been handled. Note that this method will be called automatically before the AsyncPort shutsdown.
| 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.
