An IEntityGroup is a composite, or non-leaf IGroupMember.
It contains IEntities and other IEntityGroups.
The api defines methods for adding a member to, and removing it from, a group,
though not vice versa. (Although there is nothing to prevent a given IGroupMember
implementation from storing references to its containing groups.) These methods only
change the group structure in memory.
addMember(IGroupMember gm)
removeMember(IGroupMember gm)
The following methods commit changes in the group structure to the
persistent store:
delete() - delete the group and its memberships
update() - insert or update the group, as appropriate
updateMembers() - insert/update/delete group memberships as appropriate
The following methods were added to permit an IEntityGroup to function
within a composite group service:
getLocalKey() - returns the key within the service of origin.
getServiceName() - returns the Name of the group service of origin.
setLocalGroupService() - sets the group service of origin.
