Method Detail

loadSettingsFrom

protected void loadSettingsFrom(NodeSettingsRO settings,
                                PortObjectSpec[] specs)
                         throws NotConfigurableException

Invoked before the dialog window is opened. The settings object passed, contains the current settings of the corresponding node model. The model and the dialog must agree on a mutual contract on how settings are stored in the spec. I.e. they must able to read each other's settings.

The implementation must be able to handle invalid or incomplete settings as the model may not have any reasonable values yet (for example when the dialog is opened for the first time). When an empty/invalid settings object is passed the dialog should set default values in its components.

Overrides:

loadSettingsFrom in class NodeDialogPane

Parameters:

settings - The settings to load into the dialog. Could be an empty object or contain invalid settings. But will never be null.

specs - The input data table specs. Items of the array could be null if no spec is available from the corresponding input port (i.e. not connected or upstream node does not produce an output spec). If a port is of type BufferedDataTable.TYPE and no spec is available the framework will replace null by an empty DataTableSpec (no columns) unless the port is marked as optional.

Throws:

NotConfigurableException - if the dialog cannot be opened because of real invalid settings or if any preconditions are not fulfilled, e.g. no predecessor node, no nominal column in input table, etc.

saveSettingsTo

protected void saveSettingsTo(NodeSettingsWO settings)
                       throws InvalidSettingsException

Description copied from class: NodeDialogPane

Invoked when the settings need to be applied. The implementation should write the current user settings from its components into the passed object. It should not check consistency or completeness of the settings - this is part of the model's load method. The only situation this method would throw an exception is when a component contains an invalid value that can't be stored in the settings object.
The settings must be written in a way the model is able to load in, i.e. with the model's keys.

Specified by:

saveSettingsTo in class NodeDialogPane

Parameters:

settings - write intervals to

Throws:

InvalidSettingsException - if a bin name is empty
