libCellML Tool for supporting CellML in software Supporting CellML 2.0 Open Source C++ library + bindings Apache 2.0 Licence Re-write of the CellML-API Available in Windows, OS X, and GNU/Linux
Advances from CellML-API Working with the community more closely Model the domain rather than the serialisation format C++ library + bindings Make use of C++-11 features
Key Aspects Community involvement Focused development Test Driven Write a test first to submit for review to the community Coverage Automated testing
Comparison iface::cellml_api::CellMLBootstrap* bootstrap = CreateCellMLBootstrap(); iface::cellml_api::Model* model = bootstrap->createModel(L"1.1"); bootstrap->release_ref(); iface::cellml_api::CellMLComponent* component = model->createComponent(); component->name(L component_name ); model->addElement(component); // note, don t do this or it crashes: component->release_ref(); model->release_ref(); libcellml::Model model; libcellml::ComponentPtr component = std::make_shared<libcellml::Component>(); component->setName( component_name ); model.addComponent(component);
Comparison ObjRef<iface::cellml_api::Connection> connection = model->createConnection()); model->addElement(connection); ObjRef<iface::cellml_api::MapComponents> mapComponents = connection- >componentMapping(); mapComponents->firstComponentName(L Component1_name ); mapComponents->secondComponentName(L Component2_name ); for ( ... each variable to be connected ...) { ObjRef<iface::cellml_api::MapVariables> mapVariables = model- >createMapVariables(); mapVariables->firstVariableName(L Variable1_name ); mapVariables->secondVariableName(L Variable2_name ); connection->addElement(mapVariables); }
Comparison libcellml::Model model; libcellml::ComponentPtr comp1 = std::make_shared<libcellml::Component>(); libcellml::ComponentPtr comp2 = std::make_shared<libcellml::Component>(); libcellml::VariablePtr variable1 = std::make_shared<libcellml::Variable>(); libcellml::VariablePtr variable2 = std::make_shared<libcellml::Variable>(); comp1->addVariable(variable1); comp2->addVariable(variable2); model.addComponent(comp1); model.addComponent(comp2); libcellml::Variable::addEquivalence(variable1, variable2);
