Input and Output Ports
You define ports to get input from the process and to deliver results. In these pages:
- Learn toadd portsto your operator.
- Set preconditionsto allow only certain input types in your operator and to enable meta data handling.
- 集生成规则sto reflect the changes made by your operator in the meta data.
- Use a PortPairExtenderto, for example, create throughput ports that simply pass given data through the operator. (This is mostly used to influence the execution order when the operator itself does not need input and output ports.)
