VIewID

The ViewID is used to uniquely number views. It consists of the address of the view creator and a sequence number. ViewIds can be compared for equality and put in a hashmaps as they implement equals() and hashCode(). Example:

[space-24:server1/SchemaRepository|11]

where space-24:server1 is the host name, and "SchemaRepository" is the group name (cache container in JBoss 7).
