You can use node and flow properties in a variety of ways with SPSS Modeler. They're most
commonly used as part of a script: either a standalone script, used to automate
multiple flows or operations, or a flow script, used to automate processes within a
single flow. You can also specify node parameters by using the node properties within the SuperNode.
At the most basic level, properties can also be used as a command line option for starting SPSS
Modeler. Using the -p argument as part of command line invocation, you can use a
flow property to change a setting in the flow.
| Property | Meaning |
|---|---|
s.max_size
|
Refers to the property max_size of the node named
s. |
s:samplenode.max_size
|
Refers to the property max_size of the node named s, which
must be a Sample node. |
:samplenode.max_size
|
Refers to the property max_size of the Sample node in the current flow
(there must be only one Sample node). |
s:sample.max_size
|
Refers to the property max_size of the node named s, which
must be a Sample node. |
t.direction.Age
|
Refers to the role of the field Age in the Type node
t. |
:.max_size
|
*** NOT LEGAL *** You must specify either the node name or the node type. |
The example s:sample.max_size illustrates that you don't need to spell out node
types in full.
The example t.direction.Age illustrates that some slot names can themselves be
structured—in cases where the attributes of a node are more complex than simply individual slots
with individual values. Such slots are called structured or complex
properties.
