All Implemented Interfaces:

ExampleSet, IOObject, ResultObject, LoggingHandler, java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<Example>

public class RemappedExampleSet
extends AbstractExampleSet

This example set uses the mapping given by another example set and "remaps" on the fly the nominal values according to the given set. It also sorts the regular attributes in the order of the other exampleSet if possible. If additional attributes occur, they are appended on the end of the example set, if keepAdditional is selected.

Method Detail

getAttributes

public Attributes getAttributes()

Description copied from interface: ExampleSet

Returns the data structure holding all attributes.

getExampleTable

public ExampleTable getExampleTable()

Description copied from interface: ExampleSet

Returns the underlying example table. Most operators should operate on the example set and manipulate example to change table data instead of using the table directly.

size

public int size()

Description copied from interface: ExampleSet

Returns the number of examples in this example set. This number should not be used to create for-loops to iterate through all examples.

iterator

public java.util.Iterator<Example> iterator()

getExample

public Example getExample(int index)

Description copied from interface: ExampleSet

Returns the i-th example. It is not guaranteed that asking for an example by using the index in the example table is efficiently implemented. Therefore for-loops for iterations are not an option and an ExampleReader should be used.
