[Linuxsampler-devel] Latest CVS commit

[Christian S. <chr...@ep...>]

Hi!

First off my latest commit may break things a bit, so I uploaded a CVS 
snapshot tarball before:

	http://www.linuxsampler.org/downloads.html

Rui, I propose you also upload a snapshot of a qsampler version which fits the 
best to that LS version, so that users have a working environment while we 
implement the new network protocol draft and deal with the transition due to 
this.

Now the changes:

	* src/common: added template class 'optional<>' which can be used e.g. as
	  return type whenever a value might be returned, but don't has to; this
	  template class pretty much acts like a pointer of the given type, but is
	  much more safer than a simple pointer

	* src/audiodriver: added static class AudioDeviceFactory to create audio
	  devices at runtime by using a string and to obtain driver informations
	  of drivers at runtime, driver classes should simply use the macro
	  REGISTER_AUDIO_OUTPUT_DRIVER(DriverName,DriverClass) in their cpp file
	  to register the driver to LinuxSampler (no changes needed anymore in the
	  LS code to add a new audio output driver)

	* src/drivers: added classes to dynamically manage driver parameters; there
	  are two different kinds of parameters: parameters which are need to
	  create a new device (DeviceCreationParameterX) used to e.g. create an
	  audio output device or a MIDI input device and parameters which are only
	  available at runtime, means when a device is already created
	  (DeviceRuntimeParameterX) which will be e.g. used as audio channel
	  parameters and MIDI port parameters

	* src/linuxsampler.cpp: all registered audio output drivers will be shown
	  on the console on startup

	* src/network: implemented configuration of audio output devices via LSCP

Vladimir, sorry I did not have the time to test it, so it maybe buggy as hell. 
But I hope the course is clear with the stuff I commited. MIDI device 
configuration can simply be done the same, so you just have to duplicate the 
used technics for MIDI device configuration.

This will be my last commit (major commit at least) for the next four weeks or 
so, once again exams time... Hope you guys won't let development of LS stall 
in the meantime !!!

P.S. Maybe you even get Benno to move his ass !
