Provides information about, access to, and common tools for GemFire
distributed systems. When a program wishes to access distributed dtaa
data stored in GemFire, it first creates a {@link
com.gemstone.gemfire.distributed.DistributedSystem} that will connect
to the distributed system. GemFire provides two means of discovering
the other members in a distributed group. The first uses IP multicast
to broadcast a message to all members that listen on a given port and address. The second
method of discovery uses special VMs called {@linkplain
com.gemstone.gemfire.distributed.Locator "locators"} to keep track of
the members of the distributed system. Each locator is identified by
a host/port pair that is specified when connecting
to the distributed system.
