source: pacpusframework/branches/0.1.x/src/DBITEPlayerLib/DbtPlyUserInterface.cpp@ 254

Last change on this file since 254 was 152, checked in by Marek Kurdej, 11 years ago

Major update.
Renamed: addInput -> addInputs, addOutput -> addOutputs and made pure virtual (=0).
Transformed macro definitions into template methods: ADD_INPUT -> ComponentBase::addInput, ADD_OUTPUT -> ComponentBase::addOutput, GET_INPUT -> ComponentBase::getTypedInput, GET_OUTPUT -> ComponentBase::getTypedOutput.
Fixed: added public/protected set/get methods in ComponentBase, made member fields private.
