                                int tableMaxRows)

Constructs a hub service with specified message tracker GUI expiry times. The delay times are times in milliseconds after message resolution before message representations expire and hence remove themselves from gui components.

Parameters:

random - random number generator

listRemoveDelay - expiry delay for summary icons in client list display

tableRemoveDelay - expiry delay for rows in message table display

tableMaxRows - maximum number of rows in message table (beyond this limit resolved messages may be removed early)
