R6 class representing a semi-infinite edge in dimension 2

A semi-infinite edge is given by a vertex, its origin, and a vector, its direction. Voronoï diagrams possibly have such edges.

Active bindings

O

get or set the vertex O

direction

get or set the vector direction

Methods

Public methods

• IEdge2$new()

• IEdge2$print()

• IEdge2$clone()

---

Method new()

Create a new IEdge2 object.

Usage

IEdge2$new(O, direction)

Arguments

O

the vertex O (origin)

direction

the vector direction

Returns

A new IEdge2 object.

Examples

iedge <- IEdge2$new(c(1, 1), c(2, 3))
iedge
iedge$O
iedge$O <- c(1, 0)
iedge

---

Method print()

Show instance of an IEdge2 object.

Usage

IEdge2$print(...)

Arguments

...

ignored

Examples

IEdge2$new(c(2, 0), c(3, -1))

---

Method clone()

The objects of this class are cloneable with this method.

Usage

IEdge2$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
