Returns:

slave attachment, or null if the component is unattached

addTargetJacobian

public int addTargetJacobian(SparseBlockMatrix J,
                             int bi)

Add a row to the motion target Jacobian for this motion target. The Jacobian maps state velocities u into motion target velocities vt according to

 vt = J u
 

Specified by:

Parameters:

J - motion target Jacobian

bi - block row index for the row to be added

Returns:

bi + 1

getAttachments

public void getAttachments(java.util.List<DynamicAttachment> list)

Description copied from class: Marker

Returns the attachments contained by this component. This will be called by MechModelBase when creating a complete list of all the attachments in the model.

Specified by:

getAttachments in interface HasAttachments

Overrides:

getAttachments in class Marker

updateState

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

Overrides:

transformGeometry in class Point

Parameters:

gtr - transformer implementing the transform

context - context information, including what other components are being transformed

flags - specifies conditions associated with the transformation

isDuplicatable

public boolean isDuplicatable()

Returns true if this component can be duplicated. Duplication means that we can expect to be able to make a complete copy of the component along with all it's external references. This method should return true if and only if CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) returns true.

This method is not currently used. It is intended to provide a faster way of determining if a component can be duplicated, without having to use CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) to build the list of copy references.

Specified by:

isDuplicatable in interface CopyableComponent

Overrides:

isDuplicatable in class Point

Returns:

true if this component can be duplicated.

getCopyReferences

public boolean getCopyReferences(java.util.List<ModelComponent> refs,
                                 ModelComponent ancestor)

Collects external references which must also be copied in order to duplicate this component. These references should exclude those which are contained within a specified component hierarchy. This method should return true if and only if CopyableComponent.isDuplicatable() returns true.

Specified by:

getCopyReferences in interface CopyableComponent

Overrides:

getCopyReferences in class Point

Parameters:

refs - list to which references are appended

ancestor - root node of the hierarchy from which references are to be excluded

Returns:

false if it is discovered that the component cannot be duplicated

copy

public GenericMarker copy(int flags,
                          java.util.Map<ModelComponent,ModelComponent> copyMap)

Description copied from interface: CopyableComponent

Create a copy of this component. If COPY_REFERENCES is set in flags, then any component referenced by this component should itself be set to a copy. This should be done first checking copyMap for an existing copy of the referenced component. If there is no existing copy, then a copy should be created by calling copy recursively and adding the new copy to copyMap.

Specified by:

copy in interface CopyableComponent

Overrides:

copy in class Point

Parameters:

flags - flags to control the copying

copyMap - map to possible existing instances of referenced components

Returns:

copy of this component
