Class IntegerConfigKey

Method Details

• stringToValue

  public Integer stringToValue(String txt) throws ConfigException

  Description copied from class: ConfigKey

  Decodes a string value to the value type of this key. An empty string should be interpreted as a null value, but this may cause an exception if null is not a permissible value for this key.

  Specified by:

  stringToValue in class ConfigKey<Integer>

  Parameters:

  txt - string representation of value

  Returns:

  value

  Throws:

  ConfigException

• valueToString

  public String valueToString(Integer value)

  Description copied from class: ConfigKey

  Reports a value as a string. If at all possible the roundtripping should be possible, so stringToValue(valueToString(v)).equals(v). A null value, if permitted, should be represented as an empty string.

  Specified by:

  valueToString in class ConfigKey<Integer>

  Parameters:

  value - possible value associated with this key

  Returns:

  string representation

• createSpinnerKey

  public static IntegerConfigKey createSpinnerKey(ConfigMeta meta, int dflt, int lo, int hi)

  Returns a config key that uses a JSpinner for the specifier.

  Parameters:

  meta - metadata

  dflt - default value

  lo - minimum value offered by spinner

  hi - maximum value offered by spinner

• createSpinnerPairKey

  public static IntegerConfigKey createSpinnerPairKey(ConfigMeta meta, int dflt, int posLimit, int negLimit, String posLabel, String negLabel, ReportKey<Integer> posReportKey, ReportKey<Integer> negReportKey)

  Returns a config key that uses two JSpinners to specify either a positive or a negative value. This is a bit specialised (currently used for SkyDensityPlotter), but might possibly be useful in other contexts.

  Parameters:

  meta - metadata

  dflt - default value

  posLimit - maximum value (positive)

  negLimit - minimum value (negative)

  posLabel - label for positive value spinner

  negLabel - label for negative value spinner

  posReportKey - key to report actual value used as positive; may be null

  negReportKey - key to report actual value used as negative; may be null

• createSliderKey

  public static IntegerConfigKey createSliderKey(ConfigMeta meta, int dflt, double lo, double hi, boolean log)

  Returns a config key that uses a SliderSpecifier. Note that in case of log=true, you must not supply 0 for the lower value.

  Parameters:

  meta - metadata

  dflt - default value

  lo - minimum of slider range

  hi - maximum of slider range

  log - true for logarithmic scale, false for linear
