Examples of org.xmlBlaster.util.def.PriorityEnum

org.xmlBlaster.util.def.PriorityEnum
This class simulates an enumeration for queue priorities, it ensures that only valid priorities are used.
Note that this implementation has a fixed number of priorities, namely from 0 (lowest) to 9 (highest). For performance reasons we have not used an interface in the queue implementation to hide this priority implementation (calling a method through an interface takes 20 CPU cycles instead of 2).

If you need a different set of priorities, replace this implementation or change it to support an adjustable amount of priorities.
