Method Detail

getName

public String getName()

Description copied from interface: PersistableAgentChannelsFilter

Returns the name of this filter. The default implementation forwards the call to Persistable's descriptor.

Returns:

Name of this filter, or null if this filter has no name.

getOriginChannels

public List<String> getOriginChannels()

Description copied from interface: AgentChannelsFilter

Returns a list of original channel paths accepted by this filter.

Note that if this filter is used to configure AgentStatusAggregator or any clients that rely on it (like monitoring data views), the list returned by this method may contain templates and selectors. See AgentStatusAggregator.addListener(listener, agents, channels) for details.

The default implementation returns null.

Returns:

Original channel paths accepted by this filter, or null if any original path for which AgentChannelsFilter.getDisplayPaths(org.lsst.ccs.gconsole.services.aggregator.AgentChannel) returns a non-empty list is accepted.

getDisplayPath

public String getDisplayPath(String originPath)

Description copied from interface: AgentChannelsFilter

Returns the display channel corresponding to the specified original path. If the original channel is mapped to multiple display paths, this method may return one of them, or null.

If the specified original channel is not accepted by this filter, this method should return an empty list. null should never be returned.

The default implementation returns an unmodified original path.

Parameters:

originPath - Original path.

Returns:

List of display channels.

getOriginPath

public String getOriginPath(String displayPath)

Description copied from interface: AgentChannelsFilter

Returns the original path corresponding to the specified display channel. If multiple original paths are mapped to the specified display path, this method may return one of them, or null.

The default implementation returns the display path provided as an argument.

Parameters:

displayPath - Display channel path.

Returns:

Original path, or null if the specified path does not correspond to any original channel.
