Description

It is possible to reconnect both to a session as well as a stateful service in that session via Ice. This is, however, not documented anywhere.

#
# Create on client and a stateful search service
#
client = omero.client()
sess = client.createSession()
sess.getQueryService().findAll("Image",None)
search = sess.createSearchService()

#
# Record information from the service
#
seralized = str(search)
category = search.ice_getIdentity().category

#
# In a separate process or later on...
#
client_2 = omero.client()
sess_2 = client_2.createSession(category, category)
prx = client_2.ic.stringToProxy(serialized)
search_2 = omero.api.SearchPrx.checkedCast(prx)

#
# Now it is possible to work with the same stateful service.
#
search_2.onlyType("Image")
