public class TruncatedObjectDisplay

extends BasicObjectDisplay

Output display filter that shows only the beginning and the end of several types of container objects, such as arrays, hashtables, vectors, etc so as not to clutter the work window and print large quantities of unintended output. This is especially important if we cannot trap signals to input the displaying of the output.
