Class Summary
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.
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.
AccessExampleSource This operator can be used to simplify the reading of MS Access databases.
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).

CSVExampleSource This operator can read csv files.
DasyLabDataReader This operator allows to import data from DasyLab files (.DDF) into RapidMiner.
DatabaseExampleSetWriter This operator writes an ExampleSet into an SQL database.
DatabaseExampleSource This operator reads an ExampleSet from an SQL database.
DBaseExampleSource This operator can read dbase files.
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 Reads all elements of an IOContainer from a file.
IOContainerWriter Writes all elements of the current IOContainer, i.e. all objects passed to this operator, to a file.
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.
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 This operator reads an example set from (a) file(s).
SparseFormatExampleSource Reads an example file in sparse format, i.e. lines have the form
label index:value index:value index:value...
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.
WekaModelLoader This operator reads in model files which were saved from the Weka toolkit.
XrffExampleSetWriter Writes values of all examples into an XRFF file which can be used by the machine learning library Weka.
XrffExampleSource This operator can read XRFF files known from Weka.
 

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.
