Constructor Detail

SingleExampleExampleSet

public SingleExampleExampleSet(ExampleSet exampleSet,
                               Example example)

SingleExampleExampleSet

public SingleExampleExampleSet(SingleExampleExampleSet exampleSet)

Method Detail

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.

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.

getExampleFromId

public Example getExampleFromId(double id)

Description copied from interface: ExampleSet

Returns the example with the given id value. If the example set does not contain an id attribute this method should return null. Call ExampleSet.remapIds() before using this method.

Specified by:

getExampleFromId in interface ExampleSet

Overrides:

getExampleFromId in class AbstractExampleSet

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.
