Method Detail

add

public boolean add(int v)

Adds an element to this set.

Specified by:

add in interface IntCollection

Parameters:

v - the element to add to this set.

Returns:

true if this set was modified as a result of adding v; returns false otherwise.

Throws:

UnsupportedOperationException - if the operation is not supported by this set.

IllegalArgumentException - if v is not permitted, because this set is a subset of another set.

IntCollection.addAll(IntCollection)

first

public int first()

Returns the lowest element of this set.

Returns:

the lowest element of this set.

Throws:

NoSuchElementException - if this set is empty.

headSet

public IntSortedSet headSet(int to)

Returns the subset of values lower than a specified value. The returned subset is a view of this set, so changes to the subset are reflected by this set and vice versa.

Parameters:

to - the upper bound of the returned set (not included).

Throws:

IllegalArgumentException - if to is not permitted in this set (which can be the case with returned subsets).

last

public int last()

Returns the highest element of this set.

Returns:

the highest element of this set.

Throws:

NoSuchElementException - if this set is empty.

subSet

public IntSortedSet subSet(int from,
                           int to)

Returns the subset of values lower that a specified value and higher than or equal to another specified value. The returned subset is a view of this set, so changes to the subset are reflected by this set and vice versa.

Parameters:

from - the lower bound of the returned set (included).

to - the upper bound of the returned set (not included).

Throws:

IllegalArgumentException - if from is greater than to; if from or to is not permitted in this set (which can be the case with returned subsets).

tailSet

public IntSortedSet tailSet(int from)

Returns the subset of values higher than or equal to a specified value. The returned subset is a view of this set, so changes to the subset are reflected by this set and vice versa.

Parameters:

from - the lower bound of the returned set (included).

Throws:

IllegalArgumentException - if from is not permitted in this set (which can be the case with returned subsets).
