Detailed Description

A DDGNode with trackable input Data (containing a DataTracker)

Protected Attributes

Tracking Data mechanism

each Data added to the DataTracker is tracked to be able to check if its value changed since their last clean, called by default in DataEngine::cleanDirty().

Function details

void sofa::core::DataTrackerDDGNode::addInputs ( std::initializer_list< sofa::core::objectmodel::BaseData * >  datas)

Create a DataCallback object associated with multiple Data fields.

void sofa::core::DataTrackerDDGNode::addOutputs ( std::initializer_list< sofa::core::objectmodel::BaseData * >  datas)
void sofa::core::DataTrackerDDGNode::cleanDirty ( const core::ExecParams params = nullptr)

Set dirty flag to false for the DDGNode and for all the tracked Data
