  - getSoftReferences
```
public void getSoftReferences(java.util.List<ModelComponent> refs)
```
    Appends all soft references for this component to a list. References are other components, outside of this component's immediate ancestry, on which this component depends. For example, an ExcitationComponent may refer to one or more other ExcitationComponents to act as excitation sources. A soft reference is one which can be removed from the referring component. In particular, if any soft references for a component are deleted, then that component's updateReferences() method will be called to update its internal reference information.
    
    Specified by:
    
    getSoftReferences in interface ModelComponent
    
    Overrides:
    
    getSoftReferences in class ModelComponentBase
    
    Parameters:
    
    refs - list to which soft references are appended
  - updateReferences
```
public void updateReferences(boolean undo,
                             java.util.Deque<java.lang.Object> undoInfo)
```
    May be called by the system if any of the soft references for this component are removed from the the component hierarchy. If called with undo equal to false, this component should then examine its soft references and use ComponentUtils.isConnected() to determine which of them have been disconnected from the hierarchy. Disconnected references should be removed, and sufficient information should be appended to undoInfo to allow this update to be undone if this method is called later with undo equal to true. When undoing an update, the undo information should be removed from the front of undoInfo.
    
    Specified by:
    
    updateReferences in interface ModelComponent
    
    Overrides:
    
    updateReferences in class ModelComponentBase
    
    Parameters:
    
    undo - if true, indicates that the most recent reference update should be undone, using the supplied undo information.
    
    undoInfo - if undo is false, should be used to store information allowing the reference update to be undone. Otherwise, if undo is true, then this supplied information to undo the most recent update.
  - getDefaultActivationWeight
```
public double getDefaultActivationWeight()
```
    Returns the default weight that should be used when this excitation component is being used for inverse actuation control.

    Description copied from interface: IsRenderable
    
    Returns a bit code giving rendering hints about this renderable. Current bit codes include TRANSPARENT and TWO_DIMENSIONAL.
    
    Specified by:
    
    getRenderHints in interface IsRenderable
    
    Returns:
    
    bit code of rendering hints.
  - getSelection
```
public void getSelection(java.util.LinkedList<java.lang.Object> list,
                         int qid)
```
    Description copied from interface: IsSelectable
    
    Append to list the component (or components) associated with the qid-th selection query issued by this component's render method. This will only be called if this component manages its own selection (i.e., the number nums returned by IsSelectable.numSelectionQueriesNeeded() is positive), and qid will in turn be a number between 0 and nums-1.
    
    Specified by:
    
    getSelection in interface IsSelectable
    
    Parameters:
    
    list - selected objects are appended to the end of this list
    
    qid - index of the selection query
  - scaleDistance
```
public void scaleDistance(double s)
```
  - scaleMass
```
public void scaleMass(double s)
```
  - connectToHierarchy
```
public void connectToHierarchy()
```
    Description copied from class: ModelComponentBase
    
    Called by the system after this component is added to the component hierarchy (i.e., when it is added as a child of another CompositeComponent). This method is responsible for doing any required hierarchy-dependent initialization.
    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
  - disconnectFromHierarchy
```
public void disconnectFromHierarchy()
```
    Description copied from class: ModelComponentBase
    
    Called by the system after this component is removed from the component hierarchy (i.e., when it is removed as a child of its parent). This method is responsible for any required hierarchy-dependent deinitialization.
    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
  - addFascicle
```
public void addFascicle(java.util.LinkedList<Muscle> fascicle)
```
  - getFascicles
```
public java.util.ArrayList<java.util.LinkedList<Muscle>> getFascicles()
```
  - clearFascicles
```
public void clearFascicles()
```
  - transformGeometry
```
public void transformGeometry(AffineTransform3dBase X)
```
    Description copied from interface: TransformableGeometry
    Applies an affine transformation to the geometry of this component. This method should be equivalent to
```
 TransformGeometryContext.transform (this, X, 0);
 
```
    Specified by:
    
    transformGeometry in interface TransformableGeometry
    
    Parameters:
    
    X - affine transformation to apply to the component
  - transformGeometry
```
public void transformGeometry(GeometryTransformer gtr,
                              TransformGeometryContext context,
                              int flags)
```
    Description copied from interface: TransformableGeometry
    
    Transforms the geometry of this component, using the geometry transformer gtr to transform its individual attributes. The context argument supplies information about what other components are currently being transformed, and also allows the requesting of update actions to be performed after all transform called have completed. The context is also the usual entity that calls this method, from within its TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method. The argument flags provides flags to specify various conditions associated with the the transformation. At present, the available flags are TransformableGeometry.TG_SIMULATING and TransformableGeometry.TG_ARTICULATED.
    This method is not usually called directly by applications. Instead, it is typically called from within the TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method of the context, which takes care of the various operations needed for a complete transform operation, including calling TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int) to collect other components that should be transformed, calling TransformableGeometry.transformGeometry(maspack.matrix.AffineTransform3dBase) for each component, notifying component parents that the geometry has changed, and calling any requested TransformGeometryActions. More details are given in the documentation for TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int).
    TransformGeometryContext provides a number of static convenience transform methods which take care of building the context and calling apply() for a specified set of components.
    This method should not generally call transformGeometry() for its descendant components. Instead, descendants needing transformation should be specified by adding them to the context in the method TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int).
    
    Specified by:
    
    transformGeometry in interface TransformableGeometry
    
    Parameters:
    
    gtr - transformer implementing the transform
    
    context - context information, including what other components are being transformed
    
    flags - specifies conditions associated with the transformation
  - addTransformableDependencies
```
public void addTransformableDependencies(TransformGeometryContext context,
                                         int flags)
```
    Description copied from interface: TransformableGeometry
    
    Adds to context any transformable components which should be transformed as the same time as this component. This will generally include descendant components, and may also include other components to which this component is connected in some way.
    This method is generally called from with the TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method of a TransformGeometryContext.
    
    Specified by:
    
    addTransformableDependencies in interface TransformableGeometry
    
    Parameters:
    
    context - context information, to which the dependent components are added.
    
    flags - specifies conditions associated with the transformation
