Constructor Detail

ConditionedExampleSet

public ConditionedExampleSet(ExampleSet parent,
                             Condition condition)

Creates a new example which used only examples fulfilling the given condition.

ConditionedExampleSet

public ConditionedExampleSet(ExampleSet parent,
                             Condition condition,
                             boolean inverted)

Creates a new example which used only examples fulfilling the given condition.

public ConditionedExampleSet(ConditionedExampleSet exampleSet)

Clone constructor.

Method Detail

equals

public boolean equals(java.lang.Object o)

Description copied from class: AbstractExampleSet

Returns true, if all attributes including labels and other special attributes are equal.

Specified by:

equals in interface ExampleSet

Overrides:

equals in class AbstractExampleSet

hashCode

public int hashCode()

Description copied from class: AbstractExampleSet

Returns the hash code of all attributes.

Specified by:

hashCode in interface ExampleSet

Overrides:

hashCode in class AbstractExampleSet

iterator

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

Returns a MappedExampleReader.

getExample

public Example getExample(int index)

Returns the i-th example fulfilling the condition.

size

public int size()

Counts the number of examples which fulfills the condition.

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.

createCondition

public static Condition createCondition(java.lang.String name,
                                        ExampleSet exampleSet,
                                        java.lang.String parameterString)
                                 throws ConditionCreationException

Checks if the given name is the short name of a known condition and creates it. If the name is not known, this method creates a new instance of className which must be an implementation of Condition by calling its two argument constructor passing it the example set and the parameter string

Throws:

ConditionCreationException
