List of all members.

## Public Member Functions

void | Set (const b2Vec2 &v1, const b2Vec2 &v2)
| Set this as an isolated edge.
b2Shape * | Clone (b2BlockAllocator *allocator) const
| Implement b2Shape.
int32 | GetChildCount () const
bool | TestPoint (const b2Transform &transform, const b2Vec2 &p) const
bool | RayCast (b2RayCastOutput *output, const b2RayCastInput &input, const b2Transform &transform, int32 childIndex) const
| Implement b2Shape.
void | ComputeAABB (b2AABB *aabb, const b2Transform &transform, int32 childIndex) const
void | ComputeMass (b2MassData *massData, float32 density) const

## Public Attributes

b2Vec2 | m_vertex1
| These are the edge vertices.
b2Vec2 | m_vertex2
b2Vec2 | m_vertex0
| Optional adjacent vertices. These are used for smooth collision.
b2Vec2 | m_vertex3
bool | m_hasVertex0
bool | m_hasVertex3

## Detailed Description

A line segment (edge) shape. These can be connected in chains or loops to other edge shapes. The connectivity information is used to ensure correct contact normals.
