## Detailed Description

### template<class FinalMeshItems>
class OpenMesh::Concepts::KernelT< FinalMeshItems >

This class describes the minimum interface a mesh kernel has to implement (because the resulting mesh will rely on this interface).

This is the template class the actually holds the mesh kernel implementation. All functions marked as internal should only be used by the mesh class (that inherits the kernel). The mesh may then provide wrapper functions that provide the same functionality.

Todo:
  Check, if the member list is complete.

## Member Function Documentation

## ◆ add_property()

template<class FinalMeshItems >
template<typename T >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::add_property | ( | [VEHFM] PropHandleT< T > & | _ph,
|  | const std::string & | _name = `""`
| ) |  |

Add property.

You should not use this function directly. Instead, use the convenient PropertyManager wrapper and/or one of its helper functions such as makePropertyManagerFromNew, makePropertyManagerFromExisting, or makePropertyManagerFromExistingOrNew.

Adds a property

Depending on the property handle type a vertex, (half-)edge, face or mesh property is added to the mesh. If the action fails the handle is invalid. On success the handle must be used to access the property data with property().

Parameters

  _ph | A property handle defining the data type to bind to mesh. On success the handle is valid else invalid.
  _name | Optional name of property. Following restrictions apply to the name: Maximum length of name is 256 characters The prefixes matching "^[vhefm]:" are reserved for internal usage. The expression "^<.*>$" is reserved for internal usage.

## ◆ clean()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::clean | ( |  | ) |

Delete all items, i.e.

clear all item containers. The properties will be kept

## ◆ clear()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::clear | ( |  | ) |

Delete all items, i.e.

clear all item containers. The properties will also be removed from the mesh

## ◆ face_handle()

template<class FinalMeshItems >

FaceHandle OpenMesh::Concepts::KernelT< FinalMeshItems >::face_handle | ( | HalfedgeHandle | _heh | ) | const

Get the face the halfedge belongs to.

Note
  The handle is invalid if the halfedge is a boundary halfedge

KernelFaceIter OpenMesh::Concepts::KernelT< FinalMeshItems >::faces_begin | ( |  | ) |

Kernel item iterator.

Kernel item iterator.

## ◆ garbage_collection()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::garbage_collection | ( |  | ) |

Remove all items that are marked as deleted from the corresponding containers.

Note
  All handles (and indices) to any entity (face, vertex, edge, halfedge) created before garbage collection will be out of sync with the mesh, do not use them anymore! See also Deleted Elements.
  Needs the Attributes::Status attribute
  This function may not be implemented for all kernels.

## ◆ new_edge()

template<class FinalMeshItems >

HalfedgeHandle OpenMesh::Concepts::KernelT< FinalMeshItems >::new_edge | ( | VertexHandle | _start_vertex_handle,
|  | VertexHandle | _end_vertex_handle
| ) |  |

Add a new edge from `_start_vertex_handle` to `_end_vertex_handle`.

This method should add an edge (i.e. two opposite halfedges) and set the corresponding vertex handles of these halfedges.

## ◆ new_face() [1/2]

template<class FinalMeshItems >

FaceHandle OpenMesh::Concepts::KernelT< FinalMeshItems >::new_face | ( |  | ) |

Adding a new face.

## ◆ new_vertex() [3/3]

template<class FinalMeshItems >

VertexHandle OpenMesh::Concepts::KernelT< FinalMeshItems >::new_vertex | ( | const Vertex & | _v | ) |

Add a new vertex (copied from the given one).

## ◆ prev_halfedge_handle()

template<class FinalMeshItems >

HalfedgeHandle OpenMesh::Concepts::KernelT< FinalMeshItems >::prev_halfedge_handle | ( | HalfedgeHandle | _heh | ) | const

Get the previous halfedge of the given halfedge.

The implementation should take care of an existing OpenMesh::Attributes::PrevHalfedge attribute.

## ◆ remove_last_edge()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::remove_last_edge | ( |  | ) |
| inline

Remove the last edge imidiately, i.e.

call pop_back() for the EdgeContainer. Used e.g. by the add_face() method of PolyMeshT

## ◆ remove_last_face()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::remove_last_face | ( |  | ) |
| inline

Remove the last face imidiately, i.e.

call pop_back() for the FaceContainer. Used e.g. by the add_face() method of PolyMeshT

## ◆ remove_last_vertex()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::remove_last_vertex | ( |  | ) |
| inline

Remove the last vertex imidiately, i.e.

call pop_back() for the VertexContainer.

## ◆ reserve()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::reserve | ( | size_t | _n_vertices,
|  | size_t | _n_edges,
|  | size_t | _n_faces
| ) |  |

Reserve memory for vertices, edges, faces.

Reserve memory for the mesh items vertices, edges, faces. Use this method if you can estimate the memory consumption, for instance in algorithm expanding the mesh. Depending on the underlying array type you might be better of using this method, then letting the array type decide when to increase the capacity. For instance the STL vector class `std::vector` (used in the supplied ArrayKernelT) doubles the capacity if it is exhausted. This might lead to an memory allocation exception, though an smaller increment would be enough.

## ◆ set_next_halfedge_handle()

template<class FinalMeshItems >

void OpenMesh::Concepts::KernelT< FinalMeshItems >::set_next_halfedge_handle | ( | HalfedgeHandle | _heh,
|  | HalfedgeHandle | _nheh
| ) |  |

Set the next halfedge handle.

Note
  If the previous halfedge is also stored (see OpenMesh::Attributes::PrevHalfedge) then this method also has to set this link)

## ◆ vertices_begin() [1/2]

template<class FinalMeshItems >

KernelVertexIter OpenMesh::Concepts::KernelT< FinalMeshItems >::vertices_begin | ( |  | ) |

Kernel item iterator.

## ◆ vertices_begin() [2/2]

Kernel item iterator.

## ◆ vertices_end() [1/2]

Kernel item iterator.
