+ \subsection subrouter Bus topology
+ The AudioManagerDaemon expects a bus behind each of the plugins. On one of these buses there can be several domains. In order to
+ reflect this, a domain has always a bus(plugin) and a node that it belongs to. So if a message needs to be transmitted to a domain,
+ it will always be sent to a node on a bus.
+ Here is a diagram showing the topology from the view of the AudioManagerDaemon:
+ \image html bus_topology.png
+ \subsection busname Busname
+ Since a plugin represents a bus for the AudioManagerDaemon, each plugin it has its unique name, the busname that is returned by
+ am::IAmRoutingSend::returnBusName. The AudioManagerDaemon used this information to link a plugin with a domain. All other elements like
+ sinks, sources etc are linked to domains. This is how the hierarchy looks like that is used:
+ \image html routing_hierarchy.png
- \section crossfaders Crossfaders
- Cross-faders are special elements that can perform cross-fading between two sources connected to the sinks of the crossfader. The audio of either source
- or both (mixed, during the fade) is put out at the source of the fader. Cross-fading within a source (for example from one song to another) is out of
- scope audio management and must be performed in the source.\n
- A crossfader has two sinks and one source, where one sink is the "hot" one. It is in the duty of the AudioManagerController to connect the correct
- sources to the sinks in order to perform a cross-fade. When fading is started, the hotSink changes from either HS_SINKA or HS_SINKB to HS_INTERMEDIATE,
- when the fading is finished, it changes to HS_SINKA or HS_SINKB (the sink that was "cold" before).Fading itself is done in the RoutingAdapters, the
- implementation has to ensure the smooth and synchronous change of volumes. With different rampTypes, different kinds of cross-fade ramps can be supported.
- The actual status of the "hot" sink is reported by the routingAdapter. Care has to be taken that the correct "hot" end of the crossfader is given
- at registration time.\n

+\page mainl Mainloop concept
+\section mconcept Mainloop
+The AudioManager comes with a build in mainloop that can be utilized by the plug-ins to serve their needs of communication and thread-safe calling.
+The mainloop, implemented in CAmSocketHandler works like this:\n
+\image html Mainloop.png
+
+\section sec Using the Mainloop
+Adding and removing callbacks and timers work via the am::CAmSocketHandler.\n
+To add a callback, use am::CAmSocketHandler::addFDPoll, to remove one, use am::CAmSocketHandler::removeFDPoll.\n
+To add a timer callback, use am::CAmSocketHandler::addTimer, use am::CAmSocketHandler::removeTimer and am::CAmSocketHandler::restartTimer and
+am::CAmSocketHandler::stopTimer.\n
+The mainloop is started via am::CAmSocketHandler::start_listenting and stopped via am::CAmSocketHandler::stop_listening.
+Example code can be found in am::CAmDbusWrapper.
+
+\section util Utilizing The Mainloop as Threadsafe Call Method
+The AudioManager itself is singlethreaded, so any calls from other threads inside the plugins directly to the interfaces is forbidden, the
+behavior is undefined. The reason for this is that communication and routing plugins are often only communication interfaces that can are ideally used
+with the am::CAmSocketHandler.\n
+am::CAmSerializer creates an intermediate object on the heap holding all informations of the function to be called and a pointer to the object to be called.
+After that, the class writes to a pipe witch triggers the mainloop to call the callback am::CAmSerializer::receiverCallback from the maincontext. The
+callback uses the intermediate object to do the actual call. \n
+\warning asynchronous calls can be used within the main thread, but synchronous not -> the call would block forever !\n
+For each thread that needs to use synchronous calls independent an own instance of am::CAmSerializer needs to be used.

+\page eclip Download Compile Debug
+\section dw Get the source
+For compiling the source, you need to use git and the following packages:\n
+\code
+sudo apt-get install libdbus-1-dev libsqlite3-dev doxygen libgtest-dev google-mock git cmake build-essential python2.6-dev
+\endcode
+Getting the source got works with following command
+\code
+git clone https://<kavi-account>:<kavi-password>@git.genivi.org/srv/git/AudioManager
+\endcode
+\section build Compile
+In order to build the project (out of source build), please follow these instructions on the commandline:
+\code
+mkdir /build
+cd build
+cmake ..
+\endcode
+if you want to influence the build options, you can use ccmake for example (apt-get install ccmake)
+\code
+ccmake ..
+\endcode
+You will get a menue that let's you select different options for the build. Compiling with a simple
+\code
+make
+\endcode
+after the script finished, you should have:
+- a bin/ folder which contains all executables and the libraries:
+- a build/ folder which has all build objects (erase that if you need a clean build)
+- a doc/ folder in case you turned the documentation on
+
+in order to install the AudioManager, you can do
+\code
+sudo make install
+\endcode
+package generation is supported via CPack. To build packages, you have to
+\code
+make genivi_package
+\endocde
+this will create one package if your CMake version is < 2.8.5 (all binaries stripped):
+\code
+AudioManager-<git verison>-Linux.deb
+\endcode
+if your version is above, you will get 4 packages (all binaries stripped) :
+\code
+AudioManager-<git verison>-Linux-bin.deb [AudioManager binary]
+AudioManager-<git verison>-Linux-dev.deb [header files needed to compile plugins]
+AudioManager-<git verison>-Linux-sampleplugins.deb [sample plugins]
+AudioManager-<git verison>-Linux-tests.deb [tests including tests for sample plugins,
+installed in the ~/AudioMAnagerTests]
+\endcode
+to create a tar.gz file of all sources (not including .git, build and bin folder,config files), you can do:
+\code
+make package_source
+\endcode
+This will create the following package:
+\code
+AudioManager-<git verison>-Source.tar.gz
+\endcode
+All packages will be placed in a folder called packages
+\section ec Using Eclipse
+First you need to get eclipse, for example by downloading it from http://www.eclipse.org/ use the C++ CDT version.
+Import the project with\n
+File-> import project\n
+Select "existing code as makefile project" and choose the root folder auf the AudioManager\n
+In order to build with eclipse you need to tell eclipse where the makefile can be found:\n
+In project properties enter as build command:
+\code
+"make -j4 -C build" as build command
+\endcode
+\section deb Debugging with eclipse
+For debugging you need to modify debug configurations, choose the audiomanager as binary, the debugging should work.
