  3. Design

  4. Histogram Developer Interfaces • Histogram Developer interface: • IDevHistogram: • Inherits from IHistogram1D and IDevManagedObject • Methods: • bool setBinContents(iBin, entries, height, error , centre); • bool setRms( rms); • IDevHistogramFactory • no inheritance from IHistogramFactory • Factory to create unmanaged objects • Same methods as in IHistogramFactory but without the name • IDevHistogram1D createCopy(const IHistogram1D & h); • Anaphe::HistogramFactory implements IHistogramFactory using the IDevHistogramFactory

  5. Inheritance tree for Anaphe::Histogram1D IHistogram1D IManagedObject IDevManagedObject IDevHistogram1D Anaphe::Histogram1D

  6. IDevManagedObject • IDevManagedObject • All developer interfaces for objects which are going to be stored inherits from IDevManagedObject • Store needs to know if an update is needed of an existing persistency object • Methods: bool isUpToDate(); void setUpToDate( bool isUpToDate ); bool setName( const std::string& newName ); std::string userLevelClassType();

  7. Anaphe Store • Tree is separated from Store implementation • Depends only on developer interface IStore • Store does not depend on the Tree • No dependency between Store and any particular implementation of the data objects • Store deals only with IDevHistogram, IDevClouds, IDevTuple, etc… • Copy them in the corresponding persistency objects when writing • Use developer factory interface to create them when reading • No need to use tree to create a IDevHistoframFactory

  8. IStore developer interface

  9. IDevTree interface

  10. Factory Providers • Each component library defines a unique global symbol : • FactoryProvider for all the various data objects • Histograms, Tuples, Functions and DataPointSet • StoreFactories fo each store implementation • TreeFactoryProvider for the tree • AnnotationFactory for the annotation implementation • Access to the symbol is provided through the IDevAnalysisFactory interface • When the library is loaded it registers in the AnalysisFactory • No dynamic loaded is supported but can be easley added, by implementing the AnalysisFactory with a PluginManager

  11. Tuples developer interfaces • IDevTuple • IBackingStore • Read/write a row • Bind variables Other Tuple developer Interfaces: ITupleHeader, ITupleVariableDescription, ITupleVariableStatistics

  12. Functions and Fitting • IDevFunction • IDevFunctionCatalog • IDevFunctionFactory • IDevFitter • IDevFitData • IDevFitDataIterator • IDevFitResult • IDevFitParameterSettings

  13. Conclusions • Need developer interfaces for AIDA objects : • Setter methods for efficient copying • Some common properties for storing and plotting • E.g. isValid() ? • Type information ? • Need to be able to create unmanaged objects • IDevFactories ? • Can we remove managedObject from user interface ? • Possibility to leave management to specific implementations • Now IManagedObject appear only in • IManagedObject * find(std::string path); • std::string findPath(const IManagedObject & obj); • Store interface
