setRotation for a TransformGroup

Is it true that when I call setRotation() for a TransformGroup that it only rotates that current TransformGroup and not its children as well? If I want to rotate every child connected to the group to I have to traverse the tree or is there a better way?

Thanks,

When you manipulate the transform of the transformgroup, the changes will automatically apply to all its children.
Thats the whole purpose of TransformGroups.

A transformGroup is best viewed as a coordinate system.
Its children lies in this coordinate system, and is therefore also affected when the coordinate system is e.g. rotated. Except the children does not rotate in relation to each other, but in relation to what is not children of the transformgroup.
