bool global_simpleAngular_2::checkParameters

(

)

[virtual]

subclass must check the supplied parameters ParE_, ParS_

whether they are correct and should select this paricular algorithm.

If the parameters are correct by should not select this particular algorithm, checkParamters must return false otherwise true.

The std::string err_ is to be used to be extended with error information in case any errors have been detected. Error information must be attached to err_ because of the possibility of already contained error information.

In case of errors: If an DDException is thrown by the algorithm implementation, further processing of any other implementations of the algorithm will be stopped. If no exception is thrown, checkParamters must return false. It's preferable not to throw an exception in case of errors. The algorithm implementation will throw if all checkParamters() of all registered algorithm implementations have returned false.

void global_simpleAngular_2::checkTermination

(

)

[virtual]

for algorithms with incr_==0 the algorithm must check whether to terminate

Overload this function in case the algorithm is a 'incr_==0' type. In this case provide some code which checks using perhaps the value of count_ and/or supplied algorithm parameters to check whether terminate() has to be called or not. If terminate() is called, the current iteration of the algorithm is not taken into account!

The default implementation will immidiately terminate the algorithm in case incr_==0.

In case of incr_!=0: checkTermination() is not called at all; the algorithm will terminate automatically when the specified range [start_, end_, incr_] has been covered or terminate() has been called from within translation() or rotation().
