Class TriangleElementMap

constructor

• new TriangleElementMap(initialCapacity?: number): TriangleElementMap

• Create a triangle element map with an initial allocation capacity.

  Parameters

  • initialCapacity: number = 1

    The initial allocation size for the map to grow up to

  Returns TriangleElementMap
