Creating nodes

Streams provide a number of ways of creating nodes. These methods are summarized in the following table.

Table 1. Methods for creating nodes
Method	Return type	Description
`s.create(nodeType, name)`	Node	Creates a node of the specified type and adds it to the specified stream.
`s.createAt(nodeType, name, x, y)`	Node	Creates a node of the specified type and adds it to the specified stream at the specified location. If either x < 0 or y < 0, the location is not set.
`s.createModelApplier(modelOutput, name)`	Node	Creates a model applier node that is derived from the supplied model output object.

For example, to create a new Type node in a stream you can use the following script:

stream = modeler.script.stream()
# Create a new type node
node = stream.create("type", "My Type")
