                           boolean staticOnly)

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 ModelComponentBase

Returns:

static information for all exported properties

getWeight

public double getWeight()

Description copied from interface: TrackingTarget

Queries the weight of this target.

Specified by:

getWeight in interface TrackingTarget

Returns:

target weight

See Also:

TrackingTarget.setWeight(double)

setWeight

public void setWeight(double w)

Description copied from interface: TrackingTarget

Sets the weight for this target. Target weights have a default value of 1, and are used to prioritize this target in the tracking computation. Targets with higher weights will be tracked more accurately; targets with a weight of 0 will not be tracked at all.

Specified by:

setWeight in interface TrackingTarget

Parameters:

w - new target weight

See Also:

TrackingTarget.getWeight()

getStaticOnly

public boolean getStaticOnly()

setStaticOnly

public void setStaticOnly(boolean enable)

getSubWeights

public VectorNd getSubWeights()

Description copied from interface: TrackingTarget

Queries the subweights of this target.

Specified by:

getSubWeights in interface TrackingTarget

Returns:

target subweights

See Also:

TrackingTarget.setSubWeights(maspack.matrix.VectorNd)

setSubWeights

public void setSubWeights(VectorNd weights)

Description copied from interface: TrackingTarget

Sets the subweights for this target. The number of subweights is equal to TrackingTarget.getTargetSize(), and each has a default value of 1. Subweights are multiplied by the target weight (returned by TrackingTarget.getWeight()) to yield a net weight used to prioritize each degree of freedom in the tracking computation, with higher weights resulting in more accurate tracking and a weight of 0 resulting in no tracking at all.

Specified by:

setSubWeights in interface TrackingTarget

Parameters:

weights - new target subweights

See Also:

TrackingTarget.getSubWeights()

setForceComp

public void setForceComp(ForceTargetComponent comp)

getSourceComp

public ForceTargetComponent getSourceComp()

Description copied from interface: TrackingTarget

Returns the source component associated with this target. This is the component whose positions or forces are intended to track the desired target.

Specified by:

getSourceComp in interface TrackingTarget

Returns:

target source component

getForceComp

public ForceTargetComponent getForceComp()

getTargetForce

public VectorNd getTargetForce()

setTargetForce

public void setTargetForce(VectorNd force)

getTargetSize

public int getTargetSize()

Description copied from interface: TrackingTarget

Queries the number of DOFs in the target.

Specified by:

getTargetSize in interface TrackingTarget

Returns:

number of target DOFs
