Description

Interface Summary

AddListener	These listeners will be notified after a new operator was added to a chain.
IODescription	This interface describes the (expected) input and (guaranteed) output classes of operators.
IOObject	This interface must be implemented by all objects that can be input/output objects for Operators.
Model	Model is the interface for all objects which change a data set.
ResultObject	This interface extends IOObject and is hence an object which can be handled by operators.
Saveable	Interface for resultobjects that can be saved to disc.
ValueInterface	The interface for values which can logged and plotted during process definitions.
ViewModel	The view model is typically used for preprocessing models.

Class Summary

AbstractExampleSetProcessing	Abstract superclass of all operators modifying an example set, i.e. accepting an ExampleSet as input and delivering an ExampleSet as output.
AbstractIOObject	This is an abstract superclass for all IOObject.
AbstractModel	Abstract model is the superclass for all objects which change a data set.
CommandLineOperator	This operator executes a system command.
DataMacroDefinitionOperator	(Re-)Define macros for the current process.
DefaultIODescription	This class is a description of the (expected) input and (guaranteed) output classes of operators.
FileEchoOperator	This operator simply writed the specified text into the specified file.
GroupedModel	This model is a container for all models which should be applied in a sequence.
InputDescription	This class is used to describe the required input of an operator and the operator's behavior with respect to consumption of this input object.
IOConsumeOperator	Most RapidMiner operators should define their desired input and delivered output in a senseful way.
IOContainer	Input for Operator.apply().
IOMultiplyOperator	In some cases you might want to apply different parts of the process on the same input object.
IORetrievalOperator	This operator can be used to retrieve the IOObject which was previously stored under the specified name.
IOSelectOperator	This operator allows to choose special IOObjects from the given input.
IOStorageOperator	This operator can be used to store the given IOObject into the process under the specified name (the IOObject will be "hidden" and can not be directly accessed by following operators.
ListDescription	This helper class contains information about the XML definition of a list.
MacroConstructionOperator	This operator constructs new macros from expressions which might also use already existing macros.
MacroDefinitionOperator	(Re-)Define macros for the current process.
MemoryCleanUp	Cleans up unused memory resources.
ModelApplier	This operator applies a Model to an ExampleSet.
ModelGrouper	This operator groups all input models together into a grouped (combined) model.
ModelUngrouper	This operator ungroups a previously grouped model (ModelGrouper) and delivers the grouped input models.
ModelUpdater	This operator updates a Model with an ExampleSet.
Operator	An operator accepts an array of input objects and generates an array of output objects that can be processed by other operators.
OperatorChain	A chain of operators that is subsequently applied.
OperatorDescription	Data container for name, class, short name, path and the (very short) description of an operator.
ProcessRootOperator	Each process must contain exactly one operator of this class and it must be the root operator of the process.
ResultObjectAdapter	An adapter class for the interface ResultObject.
ScriptingOperator	This operator can be used to execute arbitrary Groovy scripts.
SimpleOperatorChain	A simple operator chain which can have an arbitrary number of inner operators.
SimpleResultObject	A SimpleResulObject is only a helper class for very simple results with only a name and descriptive text.
SingleMacroDefinitionOperator	(Re-)Define macros for the current process.
SQLExecution	This operator performs an arbitrary SQL statement on an SQL database.
UnknownParameterInformation	This is a helper class storing information about unknown parameters.
Value	A value contains a key and a description.
ValueDouble	The super class for loggable double values.
ValueString	The super class for loggable String values.

Exception Summary

IllegalInputException	Will be thrown if an operator needs an input type which is not provided or gets the wrong input.
IllegalNumberOfInnerOperatorsException	Will be thrown if an operator chain has the wrong number of inner operators.
MissingIOObjectException	Will be thrown if an operator can not get its desired input.
OperatorCreationException	Exception class whose instances are thrown during the creation of operators.
OperatorException	Exception class whose instances are thrown by instances of the class Operator or of one of its subclasses.
ProcessStoppedException	Exception class whose instances are thrown by instances of the class 'Operator' or of one of its subclasses.
UserError	Exception class whose instances are thrown due to a user error, for example missing files or wrong operator architecture.
WrongNumberOfInnerOperatorsException	Will be thrown if an operator chain needs a specific number of inner operators which is not fulfilled.
