Class OperatorVersion

java.lang.Object
  com.rapidminer.gui.tools.VersionNumber
      com.rapidminer.operator.OperatorVersion

All Implemented Interfaces:

java.lang.Comparable<VersionNumber>

public class OperatorVersion
extends VersionNumber

Operators can change their behaviour from one version to another. Hence, their version is stored in the process XML file. If the behaviour of an operator changes from, say, version 5.0.003 to 5.0.004, we can notify the user in version 5.0.004. To that end, the method Operator.getCompatibilityLevel() will return 5.0.003, whereas Operator.getIncompatibleVersionChanges() will return [5.0.003] (or a superset thereof) in version [5.0.004], so that we can detect that the behavior changed. Note: The version numbers always refer to the plugin the operator is loaded from. If it is not loaded from a plugin, it refers to the RapidMiner version.
