source: trunk/FACT++/src/StateMachineDim.h@ 11189

Last change on this file since 11189 was 11063, checked in by tbretz, 13 years ago
INtroduced a new class DimLog which ensures that the MessageDimTX is initialized _before_ the DimErrorRedirecter, otherwise a very early error could be emitted to the MessageDimTX even before it was instantiated.
