Description copied from class: TopologyUtils

Query the database for information for each instance in the database topology.

Overrides:

queryForTopology in class TopologyUtils

Parameters:

conn - the connection to use to query the database.

initialHostSpec - the HostSpec that was used to initially connect.

instanceTemplate - the template HostSpec to use when constructing new HostSpec objects from the data returned by the topology query.

Returns:

a list of HostSpec objects representing the results of the topology query.
