Constructor & Destructor Documentation

JACOUSTICS::JModel::JModel ( )

inline

Default constructor.

Definition at line 493 of file JAcoustics/JModel.hh.

              :

     {}

template<class T >

JACOUSTICS::JModel::JModel	(	T	__begin,
		T	__end
	)

inline

Constructor.

This constructor can be used to set up a default model (i.e. all values at zero) for the given set of hits.
The data type corresponding to the hits should provide for the following policy methods.

   int      getString();        // get string identifier
   JEKey    getEKey();          // get emitter key

Parameters

__begin	begin of hits
__end	end of hits

Definition at line 512 of file JAcoustics/JModel.hh.

                                :
       option(JMODEL::fit_undefined_t)
     {
       for (T hit = __begin; hit != __end; ++hit) {
