Method Detail

retrieve_for_station

public Channel[] retrieve_for_station(StationId id)

Description copied from class: CacheNetworkAccess

retreives the channels for the stations, but uses the cached copy if it has been previously retrieved. The channels are also cleaned of duplicate site objects to free memory.

Specified by:

retrieve_for_station in interface NetworkAccess

Overrides:

retrieve_for_station in class CacheNetworkAccess

retrieve_stations

public Station[] retrieve_stations()

Description copied from class: CacheNetworkAccess

retreives the stations for the network, but uses the cached copy if it has been previously retrieved. The stations are also cleaned of duplicate networkAttr objects to free memory.

Specified by:

retrieve_stations in interface NetworkAccess

Overrides:

retrieve_stations in class CacheNetworkAccess
