/** @file ofcast.h
* @brief DCMTK cast macros that map to C++ casts if available
*
* DCMTK defines its own C++ cast macros that are used throughout DCMTK
* instead of the original C++ cast operators. If the C++ cast operators
* are available on the platform the macros directly map to these. Otherwise
* they map to old C-style casts.
*
* In this context, DCMTK has defined a macro OFdynamic_cast that maps to C++'
* dynamic_cast. However, so far dynamic casts are not used within DCMTK since
* they rely on C++' RTTI feature which is deliberately avoided in DCMTK at
* this moment. Thus it is highly recommended to not use dynamic casts in
* DCMTK at all.
