Method Detail

getPortObjectSerializer

public static PortObject.PortObjectSerializer<FlowVariablePortObject> getPortObjectSerializer()

getSpec

public PortObjectSpec getSpec()
Get specification to this port object. That is, the corresponding PortObjectSpec which is used to configure any successor node after execution, e.g. a BufferedDataTable can return a DataTableSpec.

Subclasses should narrow the return type if possible.

Specified by:
getSpec in interface PortObject
Returns:
underlying PortObjectSpec or any derived spec, never null.

getSummary

public String getSummary()
Get a short summary of this PortObject. The return value will be shown in a node port's tooltip, for instance.

Specified by:
getSummary in interface PortObject
Returns:
Summary of the object's content, suitable for a tooltip. Empty strings and null result values are ok (though not encouraged).

getViews

public JComponent[] getViews()
The returned views are displayed in the out port view of the referring node. Each component is displayed in an extra tab. The name of the component is used as the title for the tab. It is important that no external members are kept in the component so it can be deleted, when the port object is deleted. If the port object has no view return an empty array.

Specified by:
getViews in interface PortObject
Returns:
an array of views for the port object, each displayed as a tab in the out port view

equals

public boolean equals(Object obj)

Overrides:
equals in class Object

hashCode

public int hashCode()

Overrides:
hashCode in class Object
