Constructor Detail

SimpleSet

public SimpleSet()

Creates the empty set.

SimpleSet

public SimpleSet(java.lang.Object[] os)

Creates a set from an array of Objects.

Parameters:

os - all the elements of the new set.

SimpleSet

public SimpleSet(java.lang.Object o)

Creates a set with one element.

Parameters:

o - the Object which will be the element of the new set.

SimpleSet

public SimpleSet(int i)

Creates a set with one int as element.

Parameters:

i - the int which will be the element of the new set.

SimpleSet

public SimpleSet(int from,
                 int to)

Creates a set with a range of elements.

Parameters:

from - the first element of the set

to - the last element of the set

SimpleSet

public SimpleSet(int[] is)

Creates a set from an array of ints.

Parameters:

is - all the elements of the new set.

Method Detail

isElement

public boolean isElement(java.lang.Object e)

Checks if an Object is contained in this set. It uses the method equals(java.lang.Object, java.lang.Object) with the parameter e as second parameter to check for equality.

Specified by:

isElement in interface Set

Parameters:

e - a value of type Object

Returns:

a value of type boolean

equals

public boolean equals(java.lang.Object e1,
                      java.lang.Object e2)

Checks if two objects are equal.

Specified by:

equals in interface Set

Parameters:

e1 - a value of type Object

e2 - a value of type Object

Returns:

a value of type boolean

iterator

public java.util.Iterator iterator()

Returns an Iterator of the elements of this set.

Specified by:

iterator in interface Set

Returns:

an Iterator of all elements of this set.

size

public long size()

Returns the size of this set.

Specified by:

size in interface Set

Returns:

the number of elements

sizeSkel

public long sizeSkel()

Returns the size of the skeleton subset. This is the same as size().

Specified by:

sizeSkel in interface Set

Returns:

the number of elements in the skeleton subset.

iteratorSkel

public java.util.Iterator iteratorSkel()

Returns an Iterator of the elements of the skeleton subset of this set. This is the same as iterator.

Specified by:

iteratorSkel in interface Set

Returns:

an Iterator of all elements of the skeleton of this set.
