public class ConfigSpecifier
extends uk.ac.starlink.ttools.plot2.config.SpecifierPanel<uk.ac.starlink.ttools.plot2.config.ConfigMap>

Specifier which supplies a ConfigMap. This just aggregates specifiers for a given set of ConfigKeys; the GUI component contains a specifier component for each key, and the specified value is a map containing the values for each key.

By default the GUI component is just a stack of the constituent specifier components, but these can be decorated by supplying a suitable ConfigSpecifier.ComponentGui object.

The checkConfig method provides a hook for additional conditions that will be applied to the ConfigMap output values from this specifier.

Constructor Detail

ConfigSpecifier

public ConfigSpecifier(uk.ac.starlink.ttools.plot2.config.ConfigKey[] keys)
Constructs a config specifier with a default GUI.

Parameters:
keys - config keys to gather values for

ConfigSpecifier

public ConfigSpecifier(uk.ac.starlink.ttools.plot2.config.ConfigKey[] keys,
                       ConfigSpecifier.ComponentGui gui)
Constructs a config specifier with a custom GUI for constituent keys.

Parameters:
keys - config keys to gather values for
gui - specifier generation factory that can provide customised specifiers for different keys
Method Detail

createComponent

protected JComponent createComponent()
Specified by:
createComponent in class uk.ac.starlink.ttools.plot2.config.SpecifierPanel<uk.ac.starlink.ttools.plot2.config.ConfigMap>

getSpecifiedValue

public uk.ac.starlink.ttools.plot2.config.ConfigMap getSpecifiedValue()

checkConfig

protected void checkConfig(uk.ac.starlink.ttools.plot2.config.ConfigMap config)
                    throws uk.ac.starlink.ttools.plot2.config.ConfigException
Performs additional checks on the result produced by this specifier prior to returning the value from getSpecifiedValue(). If something is wrong with the supplied config, implementations may throw a ConfigException here to indicate the problem. Per-key specifiers ought in general to police the values that they return, but this method provides a hook for checks applying to disallowed interactions between individually legal values.

The default implementation does nothing.

Parameters:
config - config map to check
Throws:
uk.ac.starlink.ttools.plot2.config.ConfigException - if there's something wrong with the supplied map
See Also:
checkRangeSense

setSpecifiedValue

public void setSpecifiedValue(uk.ac.starlink.ttools.plot2.config.ConfigMap configMap)

submitReport

public void submitReport(uk.ac.starlink.ttools.plot2.ReportMap report)

getConfigKeys

public uk.ac.starlink.ttools.plot2.config.ConfigKey<?>[] getConfigKeys()
Returns the keys for which this specifier gathers values.

Returns:
config keys

getSpecifier

public <T> uk.ac.starlink.ttools.plot2.config.Specifier<T> getSpecifier(uk.ac.starlink.ttools.plot2.config.ConfigKey<T> key)
Returns the individual specifier used to gather values for a particular key owned by this object.

Parameters:
key - config key
Returns:
specifier for key

reportError

public void reportError(uk.ac.starlink.ttools.plot2.config.ConfigException err)
May be used by a client of this specifier to report an error associated with one of the config values obtained by this specifier. The error will be presented to the user somehow or other, and the state of the component will be altered so that the same error doesn't keep happening, at least not without further user activity.

Parameters:
err - error encountered in using a value supplied by this specifier

checkRangeSense

public static void checkRangeSense(uk.ac.starlink.ttools.plot2.config.ConfigMap config,
                                   String axName,
                                   uk.ac.starlink.ttools.plot2.config.ConfigKey<Double> minKey,
                                   uk.ac.starlink.ttools.plot2.config.ConfigKey<Double> maxKey)
                            throws uk.ac.starlink.ttools.plot2.config.ConfigException
Utility method to check that min/max keys specifying a range are not the wrong way round. Note that indefinite values at either end are OK.

Parameters:
config - config map
axName - axis name, used for error messages
minKey - config key for minimum value
maxKey - config key for maximum value
Throws:
uk.ac.starlink.ttools.plot2.config.ConfigException - if the min value is definitely greater than or equal to the max value
