Method Detail

computeSlavePos

public void computeSlavePos(VectorNd pos,
                            PointParticleAttachment at)

Description copied from class: DynamicAttachmentTestBase

Computes the position for the slave given the current state of the master components.

Specified by:

computeSlavePos in class DynamicAttachmentTestBase<PointParticleAttachment>

Parameters:

pos - returns the computed position. On input, will be set to the position state size of the slave.

at - attachment for which the position is to be computed

computeSlaveVel

public void computeSlaveVel(VectorNd vel,
                            PointParticleAttachment at)

Description copied from class: DynamicAttachmentTestBase

Computes the velocity for the slave given the current state of the master components.

Specified by:

computeSlaveVel in class DynamicAttachmentTestBase<PointParticleAttachment>

Parameters:

vel - returns the computed velocity. On input, will be set to the velocity state size of the slave.

at - attachment for which the velocity is to be computed

computeMasterForce

public void computeMasterForce(VectorNd force,
                               int idx,
                               PointParticleAttachment at)

Description copied from class: DynamicAttachmentTestBase

Computes the force for the idx-th master given the current force on the slave component. A default implementation of this method works using the GT matrix computed by the attachment. This is acceptable since the GT matrix itself is validated using computeSlaveVel(). However, subclasses can override this method if desired.

Overrides:

computeMasterForce in class DynamicAttachmentTestBase<PointParticleAttachment>

Parameters:

force - returns the computed force. On input, will be set to the velocity state size of the master.

idx - index of the master component

at - attachment for which the force is to be computed

createTestAttachment

public PointParticleAttachment createTestAttachment(int idx)

Description copied from class: DynamicAttachmentTestBase

Creates and returns an test attachment, with associated master and slave components, to be used for testing. The method will be called maxNum times, where maxNum is the value returned by DynamicAttachmentTestBase.numTestAttachments(), with the parameter num varying from 0 to maxNum-1. This allows the testing application to create different kinds of test attachments, which might be necessary in some situtations.

Specified by:

createTestAttachment in class DynamicAttachmentTestBase<PointParticleAttachment>

Parameters:

idx - instance number for the attachment to be created.

main

public static void main(java.lang.String[] args)
