What is the difference between addMembers(...) and setMembers(...) in SmartGWT

Question

What is the difference between using SmartGWT's addMembers vs. setMembers methods for adding components to a form layout?

mainLayout.addMember(northLayout);
mainLayout.addMember(southLayout);

mainLayout.addMembers(northLayout, southLayout);

vs.

mainLayout.setMembers(northLayout,southLayout);

Thank you!!
