public class DasyLabDataReader
extends BytewiseExampleSource

This operator allows to import data from DasyLab files (.DDF) into RapidMiner. Currently only universal format 1 is supported. External files (.DDB) and histogram data are currently not supported.

The parameter timestamp allows to configure whether and what kind of timestamp should be included in the example set. If it is set to relative, the timestamp attribute captures the amount of milliseconds since the file start time. If it is set to absolute, the absolute time is used to timestamp the examples.

Method Detail

getFileSuffix

protected java.lang.String getFileSuffix()

Description copied from class: BytewiseExampleSource

Returns the suffix of the files which should be read by the input operator.

Specified by:

getFileSuffix in class BytewiseExampleSource

readStream

protected ExampleSet readStream(java.io.InputStream inputStream,
                                DataRowFactory dataRowFactory)
                         throws java.io.IOException,
                                UndefinedParameterError

Description copied from class: BytewiseExampleSource

Reads the given file and constructs an example set from the read data.

Specified by:

readStream in class BytewiseExampleSource

Throws:

java.io.IOException

UndefinedParameterError

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class BytewiseExampleSource
