11 @brief Pure C interface to the AliRoot HLT component handler
12 @note Utilized by the HLT Online (PubSub) framework
16 * @defgroup alihlt_wrapper_interface The HLT wrapper interface
17 * The wrapper interface is a pure C interface which allows to use the
18 * analysis components in external applications. The interface is utilized
19 * to bind the analysis code to the PubSub framework.
