protected void loadSettingsFrom(NodeSettingsRO settings, DataTableSpec[] specs) throws NotConfigurableException
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.
loadSettingsFrom
in class NodeDialogPane
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.
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.NodeModel.loadSettingsFrom(NodeSettingsRO)
protected void saveSettingsTo(NodeSettingsWO settings) throws InvalidSettingsException
saveSettingsTo
in class NodeDialogPane
