Constructor Detail

Triple

public Triple(java.lang.Object first,
              java.lang.Object second,
              java.lang.Object third)

Constructs a new triple with the given objects.

Parameters:

first - the first element

second - the second element

third - the third, final element

Method Detail

toString

public java.lang.String toString()

Uses the toString method to concatenate the elements together in a space-seperated list. Note, it currently doesn't encode the spaces, which would be necessary to make the output parseable, and nulls would probably have to be different, somehow.

Overrides:

toString in class Pair

Returns:

the elements toString versions, concatenated.

getThird

public java.lang.Object getThird()

Gets a reference to the third element.

Returns:

reference to the third element

equals

public boolean equals(java.lang.Object o)

Compares the elements of the triple with the elements of the target triple.

Overrides:

equals in class Pair

Parameters:

o - the object to compare with

Returns:

true if all the elements of each are equal

hashCode

public int hashCode()

The xor of the three elements of this.

Overrides:

hashCode in class Pair

Returns:

first.hash ^ second.hash, basically
