Member Function Documentation

◆ is_nil()

bool GEO::MeshHalfedges::Halfedge::is_nil ( ) const
inline

Tests whether this Halfedge is initialized.

Returns
true if this Halfedge is uninitialized, false otherwise

Definition at line 100 of file mesh_halfedges.h.

◆ operator!=()

bool GEO::MeshHalfedges::Halfedge::operator!= ( const Halfedge rhs) const
inline

Tests whether this Halfedge is different from another one.

Parameters
[in]rhsthe comparand
Returns
true if this Halfedge and rhs refer to a different facet or corner, false otherwise.

Definition at line 120 of file mesh_halfedges.h.

◆ operator==()

bool GEO::MeshHalfedges::Halfedge::operator== ( const Halfedge rhs) const
inline

Tests whether this Halfedge is the same as another one.

Parameters
[in]rhsthe comparand
Returns
true if this Halfedge and rhs refer to the same facet and corner, false otherwise.
