public class Abstraction_Qualitative
extends Abstraction_Generic

Class that implements a qualitative abstraction. Two different values are possible: to be with an equal relation with respect to a previous pair (if occurs at the same time), or to be with an after relation with respect to that previous pair (the previous pair have a before relation with respect to this one) Copyright Antonio Gomariz Peñalver 2013 This file is part of the SPMF DATA MINING SOFTWARE (http://www.philippe-fournier-viger.com/spmf).

Method Detail

clear

public static void clear()

crear

public static Abstraction_Qualitative crear(boolean equalRelation)

It creates a new abstraction with the given value.

Parameters:

equalRelation - contains an equal relation

Returns:

the created abstraction

equals

public boolean equals(java.lang.Object o)

Description copied from class: Abstraction_Generic

It checks if this abstraction is equal to another

Specified by:

equals in class Abstraction_Generic

Parameters:

o - the other abstraction

Returns:

true if equal, otherwise false

hashCode

public int hashCode()

Description copied from class: Abstraction_Generic

It returns the hash code associated with an abstraction

Specified by:

hashCode in class Abstraction_Generic

Returns:

the hashcode

compareTo

public int compareTo(Abstraction_Generic o)

hasEqualRelation

public boolean hasEqualRelation()

toString

public java.lang.String toString()

Description copied from class: Abstraction_Generic

It returns a string representation of the abstraction

Specified by:

toString in class Abstraction_Generic

Returns:

the string representation

toStringToFile

public java.lang.String toStringToFile()

Get a string representation of this abstraction in SPMF format.

Specified by:

toStringToFile in class Abstraction_Generic

Returns:

the string representation

compute

public boolean compute(PseudoSequence sequence,
                       int projection,
                       int indexItemset)

It returns true if the projection indicated starts in the middle of an itemset and the abstraction is an equal relation, or if the projection starts in the first item of the itemset and the abstraction does not have an equal relation.

Specified by:

compute in class Abstraction_Generic

Parameters:

sequence - The sequence in which we apply the method

projection - The projection of the pseudosequence in which we are interested

indexItemset - the itemset index

Returns:

true if the condition is met, otherwise false.
