Method Detail

createNodePersistor

protected NodePersistorVersion200 createNodePersistor()

Overrides:

createNodePersistor in class SingleNodeContainerPersistorVersion1xx

loadNodeFactoryClassName

protected String loadNodeFactoryClassName(NodeSettingsRO parentSettings,
                                          NodeSettingsRO settings)
                                   throws InvalidSettingsException

Load factory name.

Overrides:

loadNodeFactoryClassName in class SingleNodeContainerPersistorVersion1xx

Parameters:

parentSettings - settings of outer workflow (old style workflows have it in there)

settings - settings of this node, ignored in this implementation

Returns:

Name of factory

Throws:

InvalidSettingsException - If that fails for any reason.

loadNodeFile

protected String loadNodeFile(NodeSettingsRO settings)
                       throws InvalidSettingsException

Description copied from class: SingleNodeContainerPersistorVersion1xx

Load Name of file containing node settings.

Overrides:

loadNodeFile in class SingleNodeContainerPersistorVersion1xx

Parameters:

settings - to load from, used in sub-classes, ignored here.

Returns:

"settings.xml"

Throws:

InvalidSettingsException - If that fails for any reason.

loadSNCSettings

protected SingleNodeContainer.SingleNodeContainerSettings loadSNCSettings(NodeSettingsRO settings,
                                                                          NodePersistorVersion1xx nodePersistor)

Load configuration of node.

Overrides:

loadSNCSettings in class SingleNodeContainerPersistorVersion1xx

Parameters:

settings - to load from (used in sub-classes)

nodePersistor - persistor to allow this implementation to load old-style

Returns:

node config

Throws:

InvalidSettingsException - if that fails for any reason.

loadFlowObjects

protected List<FlowObject> loadFlowObjects(NodeSettingsRO settings)
                                    throws InvalidSettingsException

Load from variables.

Overrides:

loadFlowObjects in class SingleNodeContainerPersistorVersion1xx

Parameters:

settings - to load from, ignored in this implementation (flow variables added in later versions)

Returns:

an empty list.

Throws:

InvalidSettingsException - if that fails for any reason.
