keel.Algorithms.Decision_Trees.PUBLIC.Register

All Implemented Interfaces:

java.lang.Comparable<Register>

public class Register
extends java.lang.Object
implements java.lang.Comparable<Register>

File: Register.java Data structure that is used in the construction of the decision tree. It stores the information about the value of the attribute the register is hosting, the class related to the register and one identificator of the registry. This data structure is used to build the separate list of attributes.

Constructor Detail

Register

public Register(int id,
                double value,
                int oclass)

Creates a register from a id, a value attribute and an output class of the item. It is used for attribute lists to store the data contained in the dataset.

Parameters:

id - Identifier of the register

value - Value of the corresponding attribute

oclass - Class of the register

Register

public Register(Register reg)

Creates a register from another existing register

Parameters:

reg - Original register from which we are going to create a copy

Method Detail

getIdentifier

public int getIdentifier()

Gets the identifier of the register itself

Returns:

identifier of the register

getAttributeValue

public double getAttributeValue()

Gets the value stored in the register

Returns:

value of the corresponding attribute

getOutputClass

public int getOutputClass()

Gets the class of the register

Returns:

class of the register

setIdentifier

public void setIdentifier(int id)

Replaces the value of the identifier of the register with another new identifier

Parameters:

id - New identifier of the register

setAttributeValue

public void setAttributeValue(double value)

Replaces the value of the corresponding attribute with another new value

Parameters:

value - New value of the corresponding attribute

setOutputClass

public void setOutputClass(int oclass)

Replaces the class associated with the register with another class

Parameters:

oclass - New class of the register

equals

public boolean equals(java.lang.Object obj)

Checks if a register is the same register as another object

Overrides:

equals in class java.lang.Object

Parameters:

obj - Object that is checked to see if it is the same register

Returns:

true if the registers are the same, false otherwise

See Also:

Object.equals(java.lang.Object)

hashCode

public int hashCode()

Hash-code function for the class that is used when object is inserted in a structure like a hashtable

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code obtained

See Also:

Object.hashCode()

toString

public java.lang.String toString()

Overriden function that converts the class to a string

Overrides:

toString in class java.lang.Object

Returns:

the string representation of the class

See Also:

Object.toString()

compareTo

public int compareTo(Register other_register)

Overriden function that symbolizes if the other register is equal, greater or smaller than the original register with a integer as response

Specified by:

compareTo in interface java.lang.Comparable<Register>

Parameters:

other_register - Register object to compare with.

Returns:

0 if both registers are equal, 1 if this register is greater than the other register, -1 if this register is smaller than the other register
