public class ForLoop extends AbstractForLoop implements ArrayProvider
Emulates the following for-loop for integer IDs:
- positive step size:
for (int i = lower; i <= upper; i += step)
- negative step size:
for (int i = upper; i >= lower; i += step)
The integers can be output as a single array as well.
Input/output:
- generates:
java.lang.Integer
-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel) The logging level for outputting errors and debugging output. default: WARNING
-name <java.lang.String> (property: name) The name of the actor. default: ForLoop
-annotation <adams.core.base.BaseAnnotation> (property: annotations) The annotations to attach to this actor. default:
-skip <boolean> (property: skip) If set to true, transformation is skipped and the input token is just forwarded as it is. default: false
-stop-flow-on-error <boolean> (property: stopFlowOnError) If set to true, the flow gets stopped in case this actor encounters an error; useful for critical actors. default: false
-silent <boolean> (property: silent) If enabled, then no errors are output in the console. default: false
-lower <int> (property: loopLower) The lower bound of the loop (= the first value). default: 1
-upper <int> (property: loopUpper) The upper bound of the loop. default: 10
-step <int> (property: loopStep) The step size of the loop. default: 1
-output-array <boolean> (property: outputArray) Whether to output the integers one-by-one or as array. default: false
