All Implemented Interfaces:

Comparable, Serializable

public class Quadruple

extends Triple

Used to create a tuple of four objects. Tuples can be used anywhere there is a need to group objects together, and Quadruples are used by the Tuples.zip(Collection, Collection, Collection, Collection) method.

Field Detail

quadruple

public static final Function4 quadruple

Function that creates a Quadruple.

fourth

public static final Function1 fourth

Function that returns the fourth element of the tuple.

Constructor Detail

Quadruple

public Quadruple(Object p_first,
                 Object p_second,
                 Object p_third,
                 Object p_fourth)

Creates a tuple of the four given objects.

Parameters:

p_fourth - the fourth object of the quadruple. A null value is accepted. The first three parameters are those accepted by Triple.Triple(Object, Object, Object).

See Also:

Triple.Triple(Object, Object, Object)

Method Detail

getFourth

public Object getFourth()

Returns the fourth object of the tuple.

Returns:

the fourth object of the tuple, which may be null.

setFourth

public void setFourth(Object p_fourth)

Sets the fourth object of the tuple.

Parameters:

p_fourth - the fourth object of the tuple.

hashCode

public int hashCode()

Returns the hash code associated with this object.

Overrides:

hashCode in class Triple

Returns:

the hash code associated with this object.

See Also:

Pair.hashCode()

equals

public boolean equals(Object p_object)

Determines if the given object is equal to this object, by comparing the four objects of each quadruple.

Overrides:

equals in class Triple

See Also:

Pair.equals(Object)

compareTo

public int compareTo(Object p_object)

Description copied from class: Pair

Sort tuples according to the objects that they contain. If the contained in the tuples do not implement the Comparable interface, they are left unsorted.

Specified by:

compareTo in interface Comparable

Overrides:

compareTo in class Triple

getStrings

protected List getStrings()

Returns a list of the String representations of the objects of the tuple. Here the fourth object of the tuple is added to the list.

Overrides:

getStrings in class Triple

Returns:

a list of the String representations of the objects of the tuple.
