java.lang.Object
   |
   +----semper.txlayer.util.Set

public class Set

extends Object

implements Serializable

_v

Set()

The empty constructor == empty set.

Set(Object)

Construct Set with one initial object.

Set(Object, Object)

Construct Set with two initial objects.

Set(Object, Object, Object)

Construct Set with three initial objects.

Set(Object, Object, Object, Object)

Construct Set with four initial objects.

Set(Object, Object, Object, Object, Object)

Construct Set with five initial objects.

Set(Object, Object, Object, Object, Object, Object)

Construct Set with six initial objects.

Set(Object[])

Construct Set from array.

Set(Vector)

Construct Set from Vector.

delete(Object)

Deletes an element of the set if that element is element of the set, otherwise nothing happens.

delete(Object[])

Deletes from the set all elements which are in the array and also in the set.

flatCopy()

Copies the set; the contents of both sets is the _same_.

getObjectArray()

Returns the elements of the set as an array.

insert(Object)

Inserts object o.

insert(Object[])

Inserts the objects of the array oa one after another; this call is equivalent to calling 'insert(oa[i])' on each index of oa, beginning with 0.

insert(Vector)

Inserts the objects of the Vector v one after another; this call is equivalent to calling 'insert(v.elementAt(i))' on each index of v, beginning with 0.

intersection(Set)

Gives a set which is the intersection of all sets in the set s.

intersection(Set, Set)

Gives a set which contains all elements which are in set s1 and also in set s2.

isElement(Object)

This method checks wether an Object is element of the Set.

isSubset(Set)

This method tests wether s is subset of this set.

minus(Set, Set)

Gives a set which contains all elements of set s1 and which are not in set s2.

size()

Return the number of objects in the set.

toString()

No comment.

union(Set)

Gives a set which is the union of all sets in the set s.

union(Set, Set)

Gives a set containing all elements of set s1 and set s2.

 protected Vector _v

 public Set()

The empty constructor == empty set.

 public Set(Object oa[])

Construct Set from array. Note: Nice for using with anonymous arrays, which come new with java 1.1!

 public Set(Vector v)

Construct Set from Vector.

 public Set(Object o0)

Construct Set with one initial object.

 public Set(Object o0,
            Object o1)

Construct Set with two initial objects.

 public Set(Object o0,
            Object o1,
            Object o2)

Construct Set with three initial objects.

 public Set(Object o0,
            Object o1,
            Object o2,
            Object o3)

Construct Set with four initial objects.

 public Set(Object o0,
            Object o1,
            Object o2,
            Object o3,
            Object o4)

Construct Set with five initial objects.

 public Set(Object o0,
            Object o1,
            Object o2,
            Object o3,
            Object o4,
            Object o5)

Construct Set with six initial objects. This is the maximum number of elements for this easy way of construction. For more elements, use anonyn. array, or this in combination with insert() afterwards.

 public void insert(Object o)

Inserts object o.

 public void insert(Object oa[])

Inserts the objects of the array oa one after another; this call is equivalent to calling 'insert(oa[i])' on each index of oa, beginning with 0.

 public void insert(Vector v)

Inserts the objects of the Vector v one after another; this call is equivalent to calling 'insert(v.elementAt(i))' on each index of v, beginning with 0.

 public void delete(Object o)

Deletes an element of the set if that element is element of the set, otherwise nothing happens.

 public void delete(Object oa[])

Deletes from the set all elements which are in the array and also in the set.

 public static Set union(Set s)

Gives a set which is the union of all sets in the set s. If one of the elements in s is not a set, an exception is thrown (in a soon version).

 public static Set union(Set s1,
                         Set s2)

Gives a set containing all elements of set s1 and set s2.

 public static Set intersection(Set s)

Gives a set which is the intersection of all sets in the set s. If one of the elements in s is not a set, an exception is thrown. I know that this is not really typesafe.

 public static Set intersection(Set s1,
                                Set s2)

Gives a set which contains all elements which are in set s1 and also in set s2.

 public static Set minus(Set s1,
                         Set s2)

Gives a set which contains all elements of set s1 and which are not in set s2.

 public boolean isElement(Object o)

This method checks wether an Object is element of the Set.

 public boolean isSubset(Set s)

This method tests wether s is subset of this set.

 public int size()

Return the number of objects in the set. This is named like the 'well named' Vector class.

 public Object[] getObjectArray()

Returns the elements of the set as an array. Note, that the sequence may be arbitrary.

 public String toString()

No comment.

Overrides:

toString in class Object

 public Set flatCopy()

Copies the set; the contents of both sets is the _same_.
