initializeTaskScheduler()

void sofa::simulation::SolveVisitor::initializeTaskScheduler ( )

protected

Initialize the task scheduler if it is not done already.

isThreadSafe()

bool sofa::simulation::SolveVisitor::isThreadSafe ( ) const

inlineoverridevirtual

Specify whether this action can be parallelized.

Reimplemented from sofa::simulation::Visitor.

parallelSolve()

void sofa::simulation::SolveVisitor::parallelSolve ( simulation::Node *  node )

protected

Function called if the solvers run concurrently Solving tasks are added to the list of tasks and start to run. However, there is no check that the tasks finished. This is done later, once all nodes have been traversed.

processNodeBottomUp()

void sofa::simulation::SolveVisitor::processNodeBottomUp ( simulation::Node *  )

overridevirtual

Callback method called after child node have been processed and before going back to the parent node.

Reimplemented from sofa::simulation::Visitor.

processNodeTopDown()

Visitor::Result sofa::simulation::SolveVisitor::processNodeTopDown ( simulation::Node *  )

overridevirtual

Callback method called when descending to a new node. Recursion will stop if this method returns RESULT_PRUNE.

Reimplemented from sofa::simulation::Visitor.

processSolver()

void sofa::simulation::SolveVisitor::processSolver ( simulation::Node *  node, sofa::core::behavior::OdeSolver *  b  )

virtual

sequentialSolve()

void sofa::simulation::SolveVisitor::sequentialSolve ( simulation::Node *  node )

protected

Function called if the solvers run sequentially.
