Constructs a NonEmptyCrossJoinSetSelection.


NonEmptyCrossJoinSetSelection

public NonEmptyCrossJoinSetSelection(SetSelection set1,
                                     SetSelection set2)
Constructs a NonEmptyCrossJoinSetSelection.

Method Detail

equals

public boolean equals(Object o)
Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Overrides:
equals in class Object
Parameters:
o - the reference object with which to compare.
Returns:
true if this object is the same as the obj argument; false otherwise.

Returns:
the first set to join

getSet2

public SetSelection getSet2()
Returns the second set to join.

Returns:
