 bak.pcj.set.LongRangeSet
| LongRangeSet | | public class LongRangeSet extends AbstractLongSet implements LongSortedSet,Cloneable,Serializable(Code) | | This class represents range based sets of long values.
The implementation is optimized for cases where most set elements
fall into ranges of consecutive long values.
Implementation of
LongSortedSet is supported from PCJ 1.2. Prior to 1.2, only LongSet
was implemented.

| Constructor Summary | |
| public | LongRangeSet()
Creates a new empty range set. | | public | LongRangeSet(long[] a)
Creates a new empty range set containing specified values. | | public | LongRangeSet(LongCollection c)
Creates a new range set with the same elements as a specified
collection. |
| Method Summary | |
| public boolean | add(long v)
| | public boolean | addAll(LongRangeSet c)
Adds all the elements of a specified range set to
this set.
Parameters:
c - the set whose elements to add to thisset. | | public boolean | addAll(LongRange range)
Adds a specified range to this set.
Parameters:
range - the range to add to this set. | | public boolean | addAll(long first, long last)

|
| LongRangeSet | | public LongRangeSet(long[] a)(Code) | | Creates a new empty range set containing specified values.
Parameters:
a - the values that the new set should contain.
throws:
NullPointerException - if a is null. |

collection.
Parameters:
c - the collection whose elements to add to the newset.
throws:
NullPointerException - if c is null. |
| add | | public boolean add(long v)(Code) | | |
| addAll | | public boolean addAll(long first, long last)(Code) | | Adds a specified range to this set.
Parameters:
first - the first value of the range to add to this set.
Parameters:
last - the last value of the range to add to this set. true if this set was modifiedas a result of adding the values firstto last; returns falseotherwise.
throws:
IllegalArgumentException - if first > last. |
| clear | | public void clear()(Code) | | |
| clone | | public Object clone()(Code) | | Returns a clone of this range set.
