This document will help you port your applications from DriveWorks CGF 5.14 to DriveWorks CGF 5.16.

Node API

The method dw::framework::Node::getPasses(VectorFixed<Pass*>&, dwProcessorType) has been removed, use the same named function with only one argument instead and filter the returned collection.

The interfaces dw::framework::IAsyncResetable and dw::framework::IResetable have been removed.

The interface dw::framework::SimpleSensorNode has been removed, use dw::framework::ISensorNode instead.

The following global functions have been renamed to avoid ambiguity with the static functions of concrete nodes:

• dw::framework::describeParameters() -> dw::framework::describeNodeParameters()
• dw::framework::describePasses() -> dw::framework::describeNodePasses()
• dw::framework::describeInputPorts() -> dw::framework::describeNodeInputPorts()
• dw::framework::describeOutputPorts() -> dw::framework::describeNodeOutputPorts()

NodeFactory

The NodeFactory doesn't report registration errors in dw::framework::registerNode() anymore, which is commonly invoked at library load time. Instead an application should call dw::framework::hasRegistrationErrors() at runtime to check for registration errors.

Descriptors

Previously individual constructor arguments of a node were described by a tuple. They have been replaced by a (templated) struct:

• dw::framework::ConstructorArgumentDescriptorT

Parameter Provider

The protected interface of dw::framework::JsonParameterProvider has been refactored for stricter type checking. User defined subclasses using that API will need to updated accordingly.

Miscellaneous

The enum class dw::framework::dwSerializationType and the related function dw:framework::dwSerializationTypeStringToEnumMap() have been removed from CGF since it was only used by a single node.
