public K getKey()

Gets the key for this Tuple.

Returns:

the Tuple's key

setKey

Sets the key for this Tuple.

Parameters:

key - the new key to set

Returns:

this Tuple itself to set and return

getValue

Returns:

the Tuple's value

setValue

public Tuple<K,V> setValue(V value)

Sets the value for this Tuple.

Parameters:

value - the new value to set
