- ProjectionEvents are ordered first by their x-value, and then by their
eventType. It is important that Insert events are sorted before Delete
events, so that items whose Insert and Delete events occur at the same
x-value will be correctly handled.
- Specified by:
compareTo
in interface java.lang.Comparable
