new VertexCache(maxVertexCount: number): VertexCache

- Defined in @here/harp-mapview/lib/geometry/VertexCache.ts:31
Creates a new cache with the specified maximum size.

Parameters
- maxVertexCount: number
  
  The maximum number of vertices the cache will store.
Returns VertexCache

Properties

Readonly maxVertexCount

maxVertexCount: number

The maximum number of vertices the cache will store.

Methods

clear

clear(): void

- Defined in @here/harp-mapview/lib/geometry/VertexCache.ts:45
Clears the vertex cache.

Returns void

get

get(vertexId: number, vertex: Vector3Like): boolean

- Defined in @here/harp-mapview/lib/geometry/VertexCache.ts:56
Gets a vertex from cache.

Parameters
- vertexId: number
  
  The id of the vertex to get.
- vertex: Vector3Like
  
  The vertex coordinates will be set here if found.
Returns boolean

whether the vertex was found on cache.

set

set(vertexId: number, vertex: Vector3Like): void

- Defined in @here/harp-mapview/lib/geometry/VertexCache.ts:71
Sets a vertex in cache. It's assumed there's no vertex with the same id already in cache.

Parameters
- vertexId: number
  
  The vertex id.
- vertex: Vector3Like
  
  The vertex coordinates.
Returns void
