Updating TreeViewer # (Object, String [] properties); What do properties refer to?

Question

I wondered about the parameter propertiesin the method TreeViewer#update(Object element, String[] properties). What are they? What do they relate to? I'm not sure what goes into String[]- are there predefined constants? Or are these the names of my column headers? Something else?

I could not find any example of use update()that has not nullpassed to it as a value for properties. Javadoc doesn't help me much.

Thanks!

TreeViewer is an "extended" version of the SWT class tree. Therefore, I assume that here the property should refer to the property stored in TreeItem (which can be set by calling setData (String, Object).
