Description of block interface elements
A block's interface consists of the set of parameters, input feeds, output feeds and operations it defines. You specify these items when you create a block with Software AG Designer. Software AG Designer then generates the corresponding actions.
Parameters. Parameters configure the behavior of a block. You typically use parameters to initialize the block or to modify its core behavior.
Input feeds. Input feeds connect live data streams to blocks. In each block input feed, you define input fields and map data in the stream to the appropriate input field. All the fields of an input feed are updated simultaneously.
Output feeds. Output feeds stream output data generated by the block. Each output feed is a collection of fields that all get updated simultaneously.
Operations. Operations are specific behaviors that the scenario invokes, such as starting or stopping the processing of data.
