It seems that there is no way to indicate that a parameter of an operation on a Java class accepts and array of values, as opposed to a single value, through the UML diagram editor?
OTOH, If one edits the XML model (the file.uml content), one can turn the ownedParameter element for the appropriate parameter into a node with two children upperValue and lowerValue, and then the diagram shows the type of that parameter as an array of the element type... But this is a bit of a pain.. Anyone know if there is a way to do this through the UML diagram editor?
This is using MyEclipse 8.6.1.
