Subgraph functions
List of Functions
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 Mapping Functions.
getSubgraphInputPortsCount
The function getSubgraphInputPortsCount() returns the number of input ports.
Compatibility
The function getSubgraphInputPortsCount() is available since CloverETL 4.1.0.
Example 335. Usage of getSubgraphInputPortsCount
There is a subgraph having two input ports and one output port.
The function
getSubgraphInputPortsCount() returns 2.
getSubgraphOutputPortsCount
integer getSubgraphOutputPortsCount( );The function getSubgraphOutputPortsCount() returns the number of output ports.
Compatibility
The function getSubgraphOutputPortsCount() is available since CloverETL 4.1.0.
Example 336. Usage of getSubgraphOutputPortsCount
There is a subgraph having two input ports and one output port.
The function
getSubgraphOutputPortsCount() returns 1.
isSubgraphInputPortConnected
boolean isSubgraphInputPortConnected( integer portNo );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.
Compatibility
The isSubgraphInputPortConnected() function is available since CloverETL 4.1.0.
Example 337. 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.
isSubgraphOutputPortConnected
boolean isSubgraphOutputPortConnected( integer portNo );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.
Compatibility
The isSubgraphOutputPortConnected() function is available since CloverETL 4.1.0.
Example 338. 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.
