All Implemented Interfaces:

ConfigurableComponent, Processor

@EventDriven

 @InputRequirement(value=INPUT_REQUIRED)
 @CapabilityDescription(value="Intended for load testing, this processor will create the configured number of copies of each incoming FlowFile. The original FlowFile as well as all generated copies are sent to the \'success\' relationship. In addition, each FlowFile gets an attribute \'copy.index\' set to the copy number, where the original FlowFile gets a value of zero, and all copies receive incremented integer values.")
 @WritesAttributes(value=@WritesAttribute(attribute="copy.index",description="A zero-based incrementing integer value based on which copy the FlowFile is."))
