InvokeScriptedProcessor 2.0.0

Bundle
org.apache.nifi | nifi-scripting-nar
Description
Experimental - Invokes a script engine for a Processor defined in the given script. The script must define a valid class that implements the Processor interface, and it must set a variable 'processor' to an instance of the class. Processor methods such as onTrigger() will be delegated to the scripted Processor instance. Also any Relationships or PropertyDescriptors defined by the scripted processor will be added to the configuration dialog. The scripted processor can implement public void setLogger(ComponentLog logger) to get access to the parent logger, as well as public void onScheduled(ProcessContext context) and public void onStopped(ProcessContext context) methods to be invoked when the parent InvokeScriptedProcessor is scheduled or stopped, respectively. NOTE: The script will be loaded when the processor is populated with property values, see the Restrictions section for more security implications. Experimental: Impact of sustained usage not yet verified.
