57 * Internal implementation class used to implement column modules.
59 * This class serves as a proxy between AbstractAnalysisData and the attached
60 * IAnalysisDataModule object. For each notification that
61 * AbstractAnalysisData sends, it maps it such that only the relevant columns
62 * are visible to the IAnalysisDataModule. Similarly, it implements
63 * the frame access methods of AbstractAnalysisData such that only the relevant
64 * columns are returned.
66 * \ingroup module_analysisdata
68 class AnalysisDataProxy : public AbstractAnalysisData, public IAnalysisDataModule
72 * Creates a proxy object that only presents certain columns.
74 * \param[in] firstColumn First column to present.
75 * \param[in] columnSpan Number of columns to present.
76 * \param[in] data Data object that should be wrapped.
