Constructor Detail

MissingNodeFactory

public MissingNodeFactory(NodeAndBundleInformation nodeInfo,
                          NodeSettingsRO additionalFactorySettings,
                          PortType[] ins,
                          PortType[] outs)

Constructs factories. Copies as much as possible from original node settings (provided by persistor). Args are all non-null.

Parameters:

nodeInfo - ...

additionalFactorySettings - ...

ins - ...

outs - ...

Method Detail

setCopyInternDirForWorkflowVersionChange

public void setCopyInternDirForWorkflowVersionChange(boolean value)

Set to true by persistor if the loaded workflow was saved in an old format so that a new save would convert all nodes into the new format. The node will then copy the content of the "internal" dir into temp and save it the next time the flow is saved. Most of times this flag is not set.

Parameters:

value - the copyInternDirForWorkflowVersionChange to set

createNodeModel

public MissingNodeModel createNodeModel()

Creates and returns a new instance of the node's corresponding model.

Specified by:

createNodeModel in class NodeFactory<MissingNodeModel>

Returns:

A new NodeModel for this node. Never null!

getNrNodeViews

protected int getNrNodeViews()

Returns the number of views or 0 if no view is available.

Specified by:

getNrNodeViews in class NodeFactory<MissingNodeModel>

Returns:

number of views available for this node

See Also:

NodeFactory.createNodeView(int,NodeModel)

createNodeView

public NodeView<MissingNodeModel> createNodeView(int viewIndex,
                                                 MissingNodeModel nodeModel)

Creates and returns a new node view for the given index.

Specified by:

createNodeView in class NodeFactory<MissingNodeModel>

Parameters:

viewIndex - The index for the view to create.

nodeModel - the underlying model

Returns:

a new node view for the given index

See Also:

NodeFactory.getNrNodeViews()

hasDialog

protected boolean hasDialog()

Returns true if this node provides a dialog to adjust node specific settings.

Specified by:

hasDialog in class NodeFactory<MissingNodeModel>

Returns:

true if a NodeDialogPane is available

See Also:

NodeFactory.createNodeDialogPane()

createNodeDialogPane

protected NodeDialogPane createNodeDialogPane()

Creates and returns a new node dialog pane, if NodeFactory.hasDialog() returns true.

Specified by:

createNodeDialogPane in class NodeFactory<MissingNodeModel>

Returns:

node dialog pane

See Also:

NodeFactory.hasDialog()

saveAdditionalFactorySettings

public void saveAdditionalFactorySettings(ConfigWO config)

Saves additional settings of this instance. This method is called by the framework upon workflow save and may be overwritten by subclasses.

This method is mainly used in a dynamic context, where node factories are defined through a different extension that generates a set of node factories and not just a single one. Most derived node factories will therefore not overwrite this method (e.g. none of the wizard-generated factories).

Overrides:

saveAdditionalFactorySettings in class NodeFactory<MissingNodeModel>

Parameters:

config - To read from.

addNodeDescription

protected void addNodeDescription(org.knime.node2012.KnimeNodeDocument doc)

Subclasses should add the node description elements. The KnimeNodeDocument reflects the structure given in http://www.knime.org/Node.dtd and allows one to create the node description document more easily (generated by XMLBeans (see http://xmlbeans.apache.org/)

Overrides:

addNodeDescription in class DynamicNodeFactory<MissingNodeModel>

Parameters:

doc - the document to add the description to

getType

public NodeFactory.NodeType getType()

Description copied from class: NodeFactory

Returns the type of the node.

Overrides:

getType in class NodeFactory<MissingNodeModel>

Returns:

type of missing node.
