Constructor Detail

CrossSetSelection

protected CrossSetSelection()
Constructs a CrossSetSelection.


CrossSetSelection

public CrossSetSelection(OlapSet set1,
                         OlapSet set2)
Constructs a CrossSetSelection.

public CrossSetSelection(SetSelection set1,
                         OlapSet set2)

Method Detail

add

public void add(OlapSet set)
Adds a set to cross join.

Parameters:
set - the set to add

add

public void add(SetSelection selection)
Adds a set to cross join.

Parameters:
selection - the set to add

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.
See Also:
Object.hashCode(), Hashtable

getSets

public SetSelectionList getSets()
Determines the sets to cross join.

Returns:
the sets to cross join
