Inherited methods

Name Inherited from Description
advanceBegin(): boolean Inherited IndexedCollectionInterval<IndexedXYZCollection> Add one to this.begin.
advanceEnd(): boolean Inherited 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 Inherited IndexedCollectionInterval<IndexedXYZCollection> Advance this.begin to (other.begin), i.e.
advanceToTail(other: IndexedCollectionInterval<IndexedXYZCollection>): boolean Inherited IndexedCollectionInterval<IndexedXYZCollection> Advance this.begin to (other.end-1), i.e.
localIndexToParentIndex(localIndex: number): undefined | number Inherited IndexedCollectionInterval<IndexedXYZCollection> Return (if possible) the parent index corresponding to localIndex
restrictEnd(): void Inherited IndexedCollectionInterval<IndexedXYZCollection> restrict this.end to this.points.length
setFrom(other: IndexedCollectionInterval<IndexedXYZCollection>, base?: number, limit?: number): void Inherited IndexedCollectionInterval<IndexedXYZCollection> Set this interval from another, with conditional replacements:
createBeginEnd<T extends CollectionWithLength>(points: T, begin: number, end: number): IndexedCollectionInterval<T> Static Inherited 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 Inherited IndexedCollectionInterval<IndexedXYZCollection> Create an interval which matches a collection from start <= i < end.
createComplete<T extends CollectionWithLength>(points: T): IndexedCollectionInterval<T> Static Inherited IndexedCollectionInterval<IndexedXYZCollection> Create an interval which matches a complete indexed collection.

Inherited properties

Name Type Inherited from Description
begin Inherited number IndexedCollectionInterval<IndexedXYZCollection> lower limit of index range
end Inherited number IndexedCollectionInterval<IndexedXYZCollection> upper limit (beyond) index range.
isNonEmpty Accessor Inherited ReadOnly boolean IndexedCollectionInterval<IndexedXYZCollection> Return true if length is 1 or more
isSingleton Accessor Inherited ReadOnly boolean IndexedCollectionInterval<IndexedXYZCollection> Return true if the length is exactly 1
isValidSubset Accessor Inherited 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 Inherited ReadOnly number IndexedCollectionInterval<IndexedXYZCollection> Return the number of steps possible with current begin and end
points Inherited IndexedXYZCollection IndexedCollectionInterval<IndexedXYZCollection> Any collection that has a .length member or property
