Package uk.ac.starlink.topcat.plot2
Class SubsetConfigManager
java.lang.Object
uk.ac.starlink.topcat.plot2.SubsetConfigManager
Maintains one configuration component each for a group of RowSubsets.
The configuration items are split into two types; normal ones and
ones that are centrally managed so that each time a new one is requested
it has a different default. A typical usage is to allow a different
default colour to be associated with each subset.

SubsetConfigManager
public SubsetConfigManager(NextSupplier nextSupplier, uk.ac.starlink.ttools.plot2.config.ConfigKey<?>[] otherKeys) Constructor.- Parameters:
nextSupplier
- manages dispensing different objects of the same typeotherKeys
- keys for config items not handled by the nextSupplier that should be handled by this managers configgers

getConfigKeys
public uk.ac.starlink.ttools.plot2.config.ConfigKey<?>[] getConfigKeys()Returns the config keys managed by this manager. -
hasConfigger
Indicates whether this manager currently has an initialised configuration object for the given subset. If not, then callinggetConfigger
would construct and initialise such an object.- Parameters:
rsKey
- row subset identifier- Returns:
- true iff getConfigger would do actual work
-
getConfigger
Lazily constructs and returns a SubsetConfigger for a given subset.- Parameters:
rsKey
- identifier of subset for which the configger is required- Returns:
- configger
-
setConfig
Adjusts the configuration for a given row subset managed by this object.- Parameters:
rsKey
- identifier of subset whose configuration characteristcics are to be changedconfig
- configuration options to be set; any irrelevant entries are ignored
-
getConfiggerComponent
Returns the GUI configuration component for a given row subset.- Parameters:
rsKey
- row subset identifier- Returns:
- configuration component
-
addActionListener
Adds a listener to be notified whenever the state of one of this manager's configuration components changes.- Parameters:
listener
- listener to add
-
removeActionListener
Removes a previously added listener.- Parameters:
listener
- to remove
