Returns PointGraph

Properties

graph

graph: {}

按 x 然后按 y 映射到点 id 的唯一点。即使在合并后，这将保持不变.

Type declaration

[x: number]: {}
- [y: number]: number

index

index: {}

Index of points by id.

Type declaration

[pointId: number]: IPointGraphIndexElement

insertedCount

insertedCount: number

Number of points inserted

merged

merged: {}

Map of point ids which once existed but have been merged into another id due to close proximity.

Type declaration

[pointId: number]: number

values

values: T[]

List of values inserted at points.

Methods

forEachPoint

forEachPoint(cb: (p: IPoint, values: T[], pointId?: number, el?: IPointGraphIndexElement) => void): void

迭代索引中的点.

Parameters
- cb: (p: IPoint, values: T[], pointId?: number, el?: IPointGraphIndexElement) => void
  
  Callback for each point in the index.
  - - (p: IPoint, values: T[], pointId?: number, el?: IPointGraphIndexElement): void
    - Parameters
      - p: IPoint
      - values: T[]
      - Optional pointId: number
      - Optional el: IPointGraphIndexElement
      Returns void
Returns void

getElementAtPoint

getElementAtPoint(p: IPoint): IPointGraphIndexElement

合并后获取点的索引元素.

Parameters
- p: IPoint
  
  Point to look up index element.
Returns IPointGraphIndexElement

getIdOfPoint

getIdOfPoint(p: IPoint): number

在合并后获取点的 id.

Parameters
- p: IPoint
  
  Point to look up id.
Returns number

insertValue

insertValue(value: T): number

插入值.

Parameters
- value: T
  
  Value associated with this point.
Returns number

valueId of the inserted value.

insertValueIdAtPoint

insertValueIdAtPoint(valueId: number, p: IPoint): { existed: boolean; pointId: number }

在点处插入值.

Parameters
- valueId: number
- p: IPoint
  
  Point.
Returns { existed: boolean; pointId: number }
- existed: boolean
- pointId: number

mergeNearestSinglePoints

mergeNearestSinglePoints(withinDistance: number): void

查找只有一个关联值的所有点。然后，合并到此集合中最近的其他点. 插入值后调用此值.

Parameters
- withinDistance: number
Returns void

mergePoints

mergePoints(withinDistance: number): void

合并彼此之间给定距离内的点。插入值后调用此值.

Parameters
- withinDistance: number
  
  Distance to consider points equal.
Returns void

reset

reset(): void
