Class ExtensionDefinition

java.lang.Object

org.apache.nifi.nar.ExtensionDefinition

public class ExtensionDefinition
extends Object

Provides a wrapper for the elements that make an extension unique. For example, there may be a class named org.apache.nifi.extensions.ExtensionABC that exists in a given NiFi Archive (NAR). There may also be several classes named org.apache.nifi.extensions.ExtensionABC, each in its own NAR, and each of those would be a separate extension. This class provides a mechanism by which the relevant bits to determine an extension's uniqueness can be bundled together into a single class.
