Parameters:

index - the index of the connection to get

getNumConnectionManagers

public int getNumConnectionManagers()

Returns the number of connections being maintained

removeConnection

public void removeConnection(int index)

Removes and shuts down the specified connection. If it was the only connection populating a topology, then that topology is discarded from the list.

Parameters:

index - the index of the connection to remove

pzClosing

public void pzClosing(PZManager manager)

Shuts down all connections in response to the GUI being shutdown.

getTopology

public Topology getTopology(int index)

Returns the requested connection to the backend.

Parameters:

index - the index of the connection to get

getNumTopologies

public int getNumTopologies()
