Method Detail

getDisplayPath

public String getDisplayPath(AgentChannel channel)

Description copied from interface: AgentChannelsFilter

Returns the display path corresponding to the specified original channel. This method is used directly by clients that expect each original channel to be mapped to no more than one display path. It can also be overridden to define a path returned in a singleton list by If the original channel is mapped to multiple display paths, this method may return one of them, or null if the clients that rely on mapping to a single display path should ignore the specified channel.

The default implementation forwards the call to AgentChannelsFilter.getDisplayPath(String) method. Subclasses may override it to take into account channel attributes and metadata.

Parameters:

channel - Original data channel.

Returns:

Display path, or null if the provided channel is not accepted by this filter.

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.

getOriginChannels

public List<String> getOriginChannels()

Description copied from interface: AgentChannelsFilter

Returns a list of original channel selectors that might be accepted by this filter.

The list returned by this method may contain channel selectors of several types (note that interpretation of some selectors depends on the list returned by getAgents() method):

• Complete path.
• Path template in the "[agent]/[partial path][/]" format. Templates that omit the agent name are expanded against all agents whose names are in the getAgents() list (or all agents present on the buses if that list is null). Templates that end with "/" match all channels that start with "agent/partial path/".
• Arbitrary regular expression (to be matched against the entire original path).
• Attribute selector strings in the "[agent.name=value&][agent.type=value&][agent.key[=value]&…&agent.key[=value]&][key[=value]&…&key[=value]]" format, where key and value are names and values of agent properties or static channel attributes. If value is omitted, the existence of the attribute is checked.

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.

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.

getFields

public List<String> getFields(boolean compact)

Description copied from interface: AgentChannelsFilter

Returns a list of attributes to display for each channel. The default implementation returns null.

Parameters:

compact - If true, returns a list of columns in a compact view.

Returns:

Display fields, or null if this filter does not provides any hints on what attributes should be displayed.
