Subgraph functions let user acquire details on input and output ports of subgraph. These functions are only available in subgraphs. If you use them out of a subgraph, the functions fail. If you work with subgraphs, you may need parse mapping. See .
The function getSubgraphInputPortsCount() returns the number of input ports.
Example 339. Usage of getSubgraphInputPortsCount
There is a subgraph having two input ports and one output port. The function getSubgraphInputPortsCount() returns 2.

The function getSubgraphOutputPortsCount() returns the number of output ports.
Example 340. Usage of getSubgraphOutputPortsCount
There is a subgraph having two input ports and one output port. The function getSubgraphOutputPortsCount() returns 1.

The function isSubgraphInputPortConnected() returns true if the particular subgraph input port is connected. Otherwise, it returns false.
Port numbers start from zero.
If portNo is not a valid port number of a particular subgraph (negative value or too big value), the function fails with an error.
Example 341. Usage of isSubgraphInputPortConnected
There is a subgraph having two input ports: the first one is connected, the second one is not connected.
The function isSubgraphInputPortConnected(0) returns true.
The function isSubgraphInputPortConnected(1) returns false.
The function isSubgraphInputPortConnected(2) fails.

The function isSubgraphOutputPortConnected() returns true if the particular subgraph output port is connected. Otherwise, it returns false.
Port numbers start from zero.
If portNo is not a valid port number of a particular subgraph (negative value or too big value), the function fails with an error.
Example 342. Usage of isSubgraphOutputPortConnected
There is a subgraph having two output ports: the first one is connected, the second one is not connected.
The function isSubgraphOutputPortConnected(0) returns true.
The function isSubgraphOutputPortConnected(1) returns false.
The function isSubgraphOutputPortConnected(2) fails.
