public class ItemEventKind

extends java.lang.Object

EQDATA_KIND_LOCAL: local delivery of existing info pseudo event, synthesised to satisfy patterns looking for existing items

EQDATA_KIND_PRESENT, EQDATA_KIND_BOUND: delete only - due to agent remove set internally (from NORMAL) if add event with lease arrives with previous item still in place (this would be an error with a non-leased item)

EQDATA_KIND_LEASE_RENEW, EQDATA_KIND_LEASE_EXPIRE: delete generated due to lease expire
