Method Detail

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class Point

Returns:

static information for all exported properties

setAttached

public void setAttached(DynamicAttachment ax)

Description copied from interface: DynamicAgent

Attach this component to another via a DynamicAttachment object. This method is intended for internal use by attachment components.

Specified by:

setAttached in interface DynamicAgent

Overrides:

setAttached in class DynamicComponentBase

Parameters:

ax - Specifies the attachment relationship between this component and its master(s)

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:

addTargetJacobian in interface MotionTargetComponent

Overrides:

addTargetJacobian in class Point

Parameters:

J - motion target Jacobian

bi - block row index for the row to be added

Returns:

bi + 1

updateState

public void updateState()

Specified by:

updateState in class Marker

updateAttachment

public void updateAttachment()

getAttachment

public PointSkinAttachment getAttachment()

Description copied from interface: DynamicAgent

Returns the slave attachment associated with this component, if any.

Specified by:

getAttachment in interface AttachingComponent

Specified by:

getAttachment in interface DynamicAgent

Overrides:

getAttachment in class DynamicComponentBase

Returns:

slave attachment, or null if the component is unattached

scaleDistance

public void scaleDistance(double s)

Description copied from interface: ScalableUnits

Scales all distance coordinates.

Specified by:

scaleDistance in interface ScalableUnits

Overrides:

scaleDistance in class Point

Parameters:

s - scaling factor

updatePosState

public void updatePosState()

Overrides:

updatePosState in class Point

updateVelState

public void updateVelState()

Overrides:

updateVelState in class Point

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

getHardReferences

public void getHardReferences(java.util.List<ModelComponent> refs)

Description copied from class: ModelComponentBase

Appends all hard 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 AxialSpring refers to two Point components as for it's end points. A hard reference is one which the referring component must have, and which if deleted, implies that the referring component should be deleted too.

Specified by:

getHardReferences in interface ModelComponent

Overrides:

getHardReferences in class Marker

Parameters:

refs - list to which hard references are appended

getSoftReferences

public void getSoftReferences(java.util.List<ModelComponent> refs)

Description copied from class: ModelComponentBase

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.areConnected() 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.

copy

public SkinMarker 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
