Use the following methods of the Network class to add or delete nodes. The integer value returned by the node-adding method is the handle of the newly created node, which can be used in subsequent SMILE calls.

Python

add_node(node_type: pysmile.NodeType, node_id: str) -> int

add_node(node_type: pysmile.NodeType) -> int

delete_node(node: int | str) -> None

Java

int addNode(int nodeType, String nodeId)

int addNode(int nodeType)

void deleteNode(int nodeHandle)

void deleteNode(String nodeId)

C#

int AddNode(int nodeType, string nodeId)

int AddNode(int nodeType)

void DeleteNode(int nodeHandle)

void DeleteNode(string nodeId)

R

nodeHandle <- addNode(nodeType, nodeId)

deleteNode(nodeIdOrHandle)
 

When creating a node, different SMILE wrappers expose node type identifiers in different ways: in Java and C#, they are nested classes with static integer values; in R, they are members of a network instance; and in Python, they are provided as a separate enum type.

Python

net.add_node(pysmile.NodeType.CPT, "node1")

Java

net.addNode(Network.NodeType.CPT, "node1");

C#

net.AddNode(Network.NodeType.CPT, "node1");

R

net$addNode(net$NodeType$CPT, "node1")
