B.1 Suppressing execution of I/O Plugins depending on the presence of mapping lines

You can suppress execution of I/O Plugins depending on the presence of mapping lines between I/O parameters and Guide Parts.

The following describes suppression of the I/O Plugin processing in the example of Operational Content shown below.

Figure B‒1: Example of Operational Content

If transition occurs from Process Node A to Process Node D in Operational Content in this figure, the I/O Plugins perform processing in the following order:

1. outputToNode method of the I/O Plugin placed in Process Node B

2. inputFromNode method of the I/O Plugin placed in Process Node B

3. outputToNode method of the I/O Plugin placed in Process Node C

4. inputFromNode method of the I/O Plugin placed in Process Node C

If you want to suppress the processing of the method executed in 1, confirm the following and then suppress the processing:

• The value of the ucnp.next.params.map key in the param argument of the outputToNode method is an empty Map.

If you want to suppress the processing of the method executed in 4, confirm the following and then suppress the processing:

• The value of the ucnp.current.params.map key in the param argument of the inputFromNode method is an empty Map.

Note that if you do not want to suppress the processing of the method executed in 4, draw a mapping line to the input parameter of the I/O Plugin in Process Node C. This allows the processing to be performed without being suppressed.
