Class Summary

AbstractDataReader	Abstract super class of all example sources reading from files.
AbstractExampleSetWriter	Abstract super type of example set writing operators.
AbstractExampleSource	Super class of all operators requiring no input and creating an ExampleSet.
AbstractModelLoader	Super class of all operators requiring no input and creating a Model.
AbstractReader<T extends IOObject>	Superclass of all operators that have no input and generate a single output.
AbstractReader.ReaderDescription	Describes an operator that can read certain file types.
AbstractWriter<T extends IOObject>	Superclass of all operators that take a single object as input, save it to disk and return the same object as output.
AccessDataReader	This class implements a Access database reader.
AccessDataWriter	Writes an ExampleSet to an existing Access database using the JDBC-ODBC-Bridge.
AppendingExampleSetWriter	Provides functionality to determine whether files should be overwritten or appended to.
ArffExampleSetWriter	Writes values of all examples into an ARFF file which can be used by the machine learning library Weka.
ArffExampleSource	This operator can read ARFF files known from the machine learning library Weka.
AttributeConstructionsLoader	Loads an attribute set from a file and constructs the desired features.
AttributeConstructionsWriter	Writes all attributes of an example set to a file.
AttributeWeightsLoader	Reads the weights for all attributes of an example set from a file and creates a new AttributeWeights IOObject.
AttributeWeightsWriter	Writes the weights of all attributes of an example set to a file.
BibtexExampleSource	This operator can read BibTeX files.
BytewiseExampleSource	Superclass for file data source operators which read the file byte per byte into a byte array and extract the actual data from that array.
C45ExampleSource	Loads data given in C4.5 format (names and data file).

ClusterModelReader	Reads a single cluster model from a file.
ClusterModelWriter	Write a single cluster model to a file.
CSVDataReader	A reader for CSV files.
CSVExampleSetWriter	This operator can be used to write data into CSV files (Comma Separated Values).
CSVExampleSource	Deprecated.
DasyLabDataReader	This operator allows to import data from DasyLab files (.DDF) into RapidMiner.
DatabaseDataReader	Reads an ExampleSet from an SQL Connection table.
DatabaseExampleSetWriter	This operator writes an ExampleSet into an SQL database.

ExampleSetWriter	Writes values of all examples in an ExampleSet to a file.
ExampleSource	This operator reads an example set from (a) file(s).
ExcelExampleSetWriter	This operator can be used to write data into Microsoft Excel spreadsheets.
ExcelExampleSource	This operator can be used to load data from Microsoft Excel spreadsheets.
GNUPlotOperator	Writes the data generated by a ProcessLogOperator to a file in gnuplot format.
IOContainerReader	Dummy operator doing nothing.
IOContainerWriter	Dummy operator.
IOObjectReader	Generic reader for all types of IOObjects.
IOObjectWriter	Generic writer for all types of IOObjects.
KDBExampleSource	This class can read arff, comma separated values (csv), dbase and bibtex files.
ModelLoader	Reads a Model from a file that was generated by an operator like Learner in a previous process.
ModelWriter	Writes the input model in the file specified by the corresponding parameter.
ParameterSetLoader	Reads a set of parameters from a file that was written by a ParameterOptimizationOperator.
ParameterSetWriter	Writes a parameter set into a file.
PerformanceLoader	Reads a performance vector from a given file.
PerformanceWriter	Writes the input performance vector in a given file.
RepositorySource
RepositoryStorer	This operator stores IOObjects at a location in a repository.
ResultSetExampleSource	Abstract superclass for operators that provide access to an ExampleSet via a ResultSet.
ResultWriter	This operator can be used at each point in an operator chain.
SimpleExampleSource	Deprecated.
SparseFormatExampleSource	Reads an example file in sparse format, i.e. lines have the form label index:value index:value index:value...
SpecialFormatExampleSetWriter	Writes an example set to a file using a special, user defined format.
SPSSExampleSource	This operator can read spss files.
StataExampleSource	This operator can read stata files.
ThresholdLoader	Reads a threshold from a file.
ThresholdWriter	Writes the given threshold into a file.
URLExampleSource	This operator reads an example set from an URL.

XrffExampleSource	This operator can read XRFF files known from Weka.

Exception Summary

AbstractDataReader.UnexpectedValueTypeException

Package com.rapidminer.operator.io Description

Operators to read data from files or write them into files. All operators reading or writing IO objects should extends AbstractReader or AbstractWriter to comply with e-LICO DMO and to ease specification of IO behavior.
