Constructor Detail

SettingsModelStringArray

public SettingsModelStringArray(String configName,
                                String[] defaultValue)
Creates a new object holding a string value.

Parameters:
configName - the identifier the value is stored with in the NodeSettings object
defaultValue - the initial value
Method Detail

createClone

protected SettingsModelStringArray createClone()

Specified by:
createClone in class SettingsModel
Returns:
a new instance of the same object with identical state and value(s).

getModelTypeID

protected String getModelTypeID()
Each settings model provides an ID which will be stored with its values. This is to ensure that the same type of model is used to read the values back. Otherwise an assertion will go off. Make sure to provide a unique ID - and to re-use that ID in all compatible models. IntegerModels for example should use the same ID as BoundedInteger models.

Specified by:
getModelTypeID in class SettingsModel
Returns:
a string that identifies all models that are able (and empowered) to read the values stored by this model.

getConfigName

protected String getConfigName()

Specified by:
getConfigName in class SettingsModel
Returns:
the name provided at settings model construction time. The id associated with the value.

loadSettingsForDialog

protected void loadSettingsForDialog(NodeSettingsRO settings,
                                     PortObjectSpec[] specs)
                              throws NotConfigurableException
Read the value(s) of this settings model from configuration object. If the value is not stored in the config, the objects value must remain unchanged. Called only from within the components using this model. If the model is disabled it should not throw the exception.
This method must always notify change listeners!!
NOTE: Do not call this method directly, rather call dlgLoadSettingsFrom

Specified by:
loadSettingsForDialog in class SettingsModel
Parameters:
settings - The NodeSettings to read from.
specs - The input specs.
Throws:
NotConfigurableException - if the specs are not good enough to

saveSettingsForDialog

protected void saveSettingsForDialog(NodeSettingsWO settings)
                              throws InvalidSettingsException
Write value(s) of this component model to configuration object. Called only from within the components using this model.
NOTE: Don't call this method directly, rather use dlgSaveSettingsTo.

Specified by:
saveSettingsForDialog in class SettingsModel
Parameters:
settings - The NodeSettings to read from.
Throws:
InvalidSettingsException - if the user has entered wrong values.

setStringArrayValue

public void setStringArrayValue(String[] newValue)
set the value stored to (a copy of) the new value.

Parameters:
newValue - the new value to store.

getStringArrayValue

public String[] getStringArrayValue()
Returns:
the (a copy of the) current value stored.

validateSettingsForModel

protected void validateSettingsForModel(NodeSettingsRO settings)
                                 throws InvalidSettingsException
Read the expected values from the settings object, without assigning them to the internal variables! (Is not called when the model was disabled at the time the settings were saved.)

Specified by:
validateSettingsForModel in class SettingsModel
Parameters:
settings - the object to read the value(s) from
Throws:
InvalidSettingsException - if the value(s) in the settings object are invalid.

loadSettingsForModel

protected void loadSettingsForModel(NodeSettingsRO settings)
                             throws InvalidSettingsException
Read value(s) of this settings model from the configuration object. If the value is not stored in the config, an exception will be thrown.
NOTE: Don't call this method directly, rather call loadSettingsFrom.

Specified by:
loadSettingsForModel in class SettingsModel
Parameters:
settings - The NodeSettings to read from.
Throws:
InvalidSettingsException - if load fails.

saveSettingsForModel

protected void saveSettingsForModel(NodeSettingsWO settings)
Write value(s) of this settings model to configuration object.
NOTE: Don't call this method directly, rather call saveSettingsTo.

Specified by:
saveSettingsForModel in class SettingsModel
Parameters:
settings - The NodeSettings to write into.

toString

public String toString()
Derived classes should print their class name plus the config name for nice and useful error messages. Like that,
return getClass().getSimpleName() + " ('" + m_configName + "')";

Specified by:
toString in class SettingsModel
