Function details

◆ build()

void sofa::component::linearsystem::MappingGraph::build ( const sofa::core::ExecParams params,
core::objectmodel::BaseContext rootNode 
)

Build the graph: mandatory to get valid data from the functions that use the graph.

◆ getBottomUpMappingsFrom()

sofa::type::vector< core::BaseMapping * > sofa::component::linearsystem::MappingGraph::getBottomUpMappingsFrom ( BaseMechanicalState mstate) const

◆ getMainMechanicalStates()

const sofa::type::vector< core::behavior::BaseMechanicalState * > & sofa::component::linearsystem::MappingGraph::getMainMechanicalStates ( ) const

Return the list of all mechanical states which are not mapped.

◆ getMappingInputs()

sofa::type::vector< BaseMechanicalState * > sofa::component::linearsystem::MappingGraph::getMappingInputs ( BaseMechanicalState mstate) const

Returns all mechanical states which are input of a mapping where the mechanical state in parameter is an output

◆ getPositionInGlobalMatrix() [1/2]

type::Vec2u sofa::component::linearsystem::MappingGraph::getPositionInGlobalMatrix ( BaseMechanicalState mstate) const

Return where in the global matrix the provided mechanical state writes its contribution.

◆ getPositionInGlobalMatrix() [2/2]
