| constructor(points: IndexedXYZCollection, base: number, limit: number): IndexedXYZCollectionInterval Protected |
Inherited methods
| Name | Inherited from | Description |
|---|---|---|
| advanceBegin(): boolean | IndexedCollectionInterval<IndexedXYZCollection> | Add one to this.begin. |
| advanceEnd(): boolean | IndexedCollectionInterval<IndexedXYZCollection> | advance this.end (but do not go beyond this.points.length) return true if the interval is still live. |
| advanceToHead(other: IndexedCollectionInterval<IndexedXYZCollection>): boolean | IndexedCollectionInterval<IndexedXYZCollection> | Advance this.begin to (other.begin), i.e. |
| advanceToTail(other: IndexedCollectionInterval<IndexedXYZCollection>): boolean | IndexedCollectionInterval<IndexedXYZCollection> | Advance this.begin to (other.end-1), i.e. |
| localIndexToParentIndex(localIndex: number): undefined | number | IndexedCollectionInterval<IndexedXYZCollection> | Return (if possible) the parent index corresponding to localIndex |
| restrictEnd(): void | IndexedCollectionInterval<IndexedXYZCollection> | restrict this.end to this.points.length |
| setFrom(other: IndexedCollectionInterval<IndexedXYZCollection>, base?: number, limit?: number): void | IndexedCollectionInterval<IndexedXYZCollection> | Set this interval from another, with conditional replacements: |
| createBeginEnd<T extends CollectionWithLength>(points: T, begin: number, end: number): IndexedCollectionInterval<T> Static | IndexedCollectionInterval<IndexedXYZCollection> | Create an interval which matches a collection from start <= i < end. |
| createBeginLength<T extends CollectionWithLength>(points: T, begin: number, length: number): IndexedCollectionInterval<T> Static | IndexedCollectionInterval<IndexedXYZCollection> | Create an interval which matches a collection from start <= i < end. |
| createComplete<T extends CollectionWithLength>(points: T): IndexedCollectionInterval<T> Static | IndexedCollectionInterval<IndexedXYZCollection> | Create an interval which matches a complete indexed collection. |
Inherited properties
| Name | Type | Inherited from | Description |
|---|---|---|---|
| begin | number | IndexedCollectionInterval<IndexedXYZCollection> | lower limit of index range |
| end | number | IndexedCollectionInterval<IndexedXYZCollection> | upper limit (beyond) index range. |
| isNonEmpty Accessor ReadOnly | boolean | IndexedCollectionInterval<IndexedXYZCollection> | Return true if length is 1 or more |
| isSingleton Accessor ReadOnly | boolean | IndexedCollectionInterval<IndexedXYZCollection> | Return true if the length is exactly 1 |
| isValidSubset Accessor ReadOnly | boolean | IndexedCollectionInterval<IndexedXYZCollection> | Return true if * the interval is empty (the empty set is a subset of all sets!) * all indices in its range are valid. |
| length Accessor ReadOnly | number | IndexedCollectionInterval<IndexedXYZCollection> | Return the number of steps possible with current begin and end |
| points | IndexedXYZCollection | IndexedCollectionInterval<IndexedXYZCollection> | Any collection that has a .length member or property |
