Constructor & Destructor Documentation

IMP::kinematics::Joint::Joint ( IMP::core::RigidBody  parent,
IMP::core::RigidBody  child 
)

An abstract class for a joint between a parent and a child

Parameters
parentrigid body upstream of this joint
childrigid body downstream of this joint
Note
we currently assume that a parent cannot be switched

Member Function Documentation

virtual const IMP::algebra::Transformation3D& IMP::kinematics::Joint::get_transformation_child_to_parent ( ) const
virtual

returns the transformation of a vector from the child reference frame to the parent reference frame in a safe way (= after updating internal coordinates if needed)

virtual const IMP::algebra::Transformation3D& IMP::kinematics::Joint::get_transformation_child_to_parent_no_checks ( ) const
protectedvirtual

returns the transformation of a vector from the child reference frame to the parent reference frame, without any checks (= without updating internal coordinates even if needed)

Definition at line 79 of file Joint.h.

virtual ::IMP::base::VersionInfo IMP::kinematics::Joint::get_version_info ( ) const
virtual

Get information about the module and version of the object.

Reimplemented from IMP::base::Object.

Definition at line 37 of file Joint.h.

void IMP::kinematics::Joint::set_owner_kf ( KinematicForest kf)
protected

this sets the kinematic forest that manages this joint, and also declares it as used (

+ Here is the call graph for this function:

void IMP::kinematics::Joint::set_transformation_child_to_parent_no_checks ( IMP::algebra::Transformation3D  transformation)
protected

Sets the transformation from parent to child reference frame (without any checks that internal coords are updated, and without marking the owner internal coords as changed)

Definition at line 99 of file Joint.h.

virtual void IMP::kinematics::Joint::update_child_node_reference_frame ( ) const
protectedvirtual

Updates the reference frame of the rigid body directly downstream of this joint

Reimplemented in IMP::kinematics::CompositeJoint, and IMP::kinematics::RevoluteJoint.

virtual void IMP::kinematics::Joint::update_joint_from_cartesian_witnesses ( )
protectedvirtual

Updates the joint transformation based on external coordinates of 'witness' particles.

Note
It is assumed that external coordinates are updated before calling this function.
Witness particles do not necessarily belong to the child or parent rigid bodes.

Reimplemented in IMP::kinematics::CompositeJoint, IMP::kinematics::RevoluteJoint, and IMP::kinematics::PrismaticJoint.
