void protocols::loops::loop_closure::kinematic_closure::NeighborDependentTabooSamplingKinematicPerturber::perturb_chain ( core::pose::Pose const &  pose, utility::vector1< core::Real > &  torsions, utility::vector1< core::Real > &  bond_ang, utility::vector1< core::Real > &  bond_len  )

virtual

function that perturbs the chain, i.e. sets new values

for the torsions, bond angles and bond lengths note: the torsions/angles/lengths that are input to this function will be identical to the ones in the pose, i.e. only the dof values that are explicitly set by this function plus the pivots will have changed after loop closure

Implements protocols::loops::loop_closure::kinematic_closure::KinematicPerturber.

virtual

after the kinmover has closed the loop, the perturber needs

to put the solutions into the pose note: the base class version of this function sets the torsions, so any KinematicPerturber that only changes the torsions will not have to implement this function
