public class Injector extends AbstractTransformer implements ControlActor
Injects a string token into the token sequence.
The string can be inject before or after the current token. One can also control how often the string gets injected, i.e., every n-th token.
Input/output:
- accepts:
java.lang.Object
- generates:
java.lang.Object
-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: Injector
-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; Note: the enclosing actor handler must have this enabled as well. default: false
-type <STRING|STORAGE> (property: type) The type of data to inject. default: STRING
-location <BEFORE|AFTER|INPLACE> (property: location) The location where to inject the data. default: AFTER
-injection <java.lang.String> (property: injection) The string to inject into the sequence; tab and newline can be inserted as escaped sequence: \t and \n default: inject_me
-conversion <adams.data.conversion.ConversionFromString> (property: conversion) The conversion to apply to the string before injecting it. default: adams.data.conversion.StringToString
-storage-name <adams.flow.control.StorageName> (property: storageName) The name of the storage item to inject. default: storage
-nth <int> (property: everyNth) The number of tokens after which the injection takes place. default: 1 minimum: 1
