virtual void MBMesquite::Instruction::initialize_queue ( MeshDomainAssoc mesh_and_domain,
const Settings settings,
MsqError err 
) [pure virtual]

Called for all instructions in queue before loop_over_mesh is called for any insetruction in queue. Default behavior is to do nothing.

Implemented in MBMesquite::QualityAssessor, DummyVertexSlaver, MBMesquite::TagVertexMesh, MBMesquite::SlaveBoundaryVertices, MBMesquite::QualityImprover, MBMesquite::MeshTransform, MBMesquite::VertexMover, and MBMesquite::TargetWriter.

void Instruction::initialize_vertex_byte ( MeshDomainAssoc mesh_and_domain,
const Settings settings,
MsqError err 
) [static]

Using data from query methods in MeshInterface or calculating as necessary depending on values in Settings, initialize MSQ_HARD_FIXED and MSQ_SLAVED flags on vertices, and clear MSQ_CULLED flag on all vertices. SLAVE_ALL setting is handled in PatchData rather than here for efficiency.
