| Interval | | public class Interval (Code) | | An immutable inclusive interval a..b
|
| Constructor Summary | |
| public | Interval(int a, int b)
|
| INTERVAL_POOL_MAX_VALUE | | final public static int INTERVAL_POOL_MAX_VALUE(Code) | | |
| Interval | | public Interval(int a, int b)(Code) | | |
| adjacent | | public boolean adjacent(Interval other)(Code) | | Are two intervals adjacent such as 0..41 and 42..42?
|
| create | | public static Interval create(int a, int b)(Code) | | Interval objects are used readonly so share all with the
same single value a==b up to some max size. Use an array as a perfect hash.
Return shared object for 0..INTERVAL_POOL_MAX_VALUE or a new
Interval object with a..a in it. On Java.g, 218623 IntervalSets
have a..a (set with 1 element).
public static Interval create(int a, int b) {
if ( a!=b || a<0 || a>INTERVAL_POOL_MAX_VALUE ) {
return new Interval(a,b);
}
if ( intervals[a]==null ) {
intervals[a] = new Interval(a,a);
}
return intervals[a];
}
ACK! Fuond out that add() actually modifies intervals. :(
|
| differenceNotProperlyContained | | public Interval differenceNotProperlyContained(Interval other)(Code) | | Return the interval with elements from this not in other;
other must not be totally enclosed (properly contained)
within this, which would result in two disjoint intervals
instead of the single one returned by this method.
|
| disjoint | | public boolean disjoint(Interval other)(Code) | | Are both ranges disjoint? I.e., no overlap?
|
| intersection | | public Interval intersection(Interval other)(Code) | | Return the interval in common between this and o
|
| startsAfter | | public boolean startsAfter(Interval other)(Code) | | Does this.a start after other.b? May or may not be disjoint
|
| startsAfterDisjoint | | public boolean startsAfterDisjoint(Interval other)(Code) | | Does this start completely after other? Disjoint
|
| startsAfterNonDisjoint | | public boolean startsAfterNonDisjoint(Interval other)(Code) | | Does this start after other? NonDisjoint
|
| startsBeforeDisjoint | | public boolean startsBeforeDisjoint(Interval other)(Code) | | Does this start completely before other? Disjoint
|
| startsBeforeNonDisjoint | | public boolean startsBeforeNonDisjoint(Interval other)(Code) | | Does this start at or before other? Nondisjoint
