Method Detail

getQP

public void getQP(MatrixNd Q,
                  VectorNd p,
                  double t0,
                  double t1)

Description copied from interface: QPCostTerm

Adds the contribution of this term to the quadratic cost components Q and p.

Parameters:

Q - quadratic term

p - proportional term

t0 - time at start of step

t1 - time at end of step

connectToHierarchy

public void connectToHierarchy(CompositeComponent hcomp)

Called by the system after this component, or an ancestor of this component, is added to the component hierarchy (i.e., added as a child of another CompositeComponent). This method is responsible for doing any required hierarchy-dependent initialization, including any updating of referenced components.

When this method is called, ModelComponent.getParent() will return the new parent component; the system will have set this beforehand.

Specified by:

connectToHierarchy in interface ModelComponent

Overrides:

connectToHierarchy in class ModelComponentBase

Parameters:

hcomp - hierarchy component to which this component, or its ancestor, was attached

disconnectFromHierarchy

public void disconnectFromHierarchy(CompositeComponent hcomp)

Called by the system after this component, or an ancestor of this component, is removed from the component hierarchy (i.e., removed as a child of its parent). This method is responsible for any required hierarchy-dependent deinitialization, including any updating of referenced components.

When this method is called, ModelComponent.getParent() will still return this original parent component; the system will set this to null after.

Specified by:

disconnectFromHierarchy in interface ModelComponent

Overrides:

disconnectFromHierarchy in class ModelComponentBase

Parameters:

hcomp - hierarchy component from which this component, or its ancestor, was detached
