updateRepetitionEstimates
public void updateRepetitionEstimates(double repetitions)
Description copied from class:StatementBlockUpdates the repetition estimate for this statement block and all contained hops. FunctionStatementBlocks are loaded from the function dictionary and repetitions are estimated for the contained statement blocks. This method is overridden in the subclasses of StatementBlock.- Overrides:
