Detailed Description

Stores the facet corners of a mesh (low-level store)

Definition at line 867 of file mesh.h.

Member Function Documentation

◆ adjacent_facet()

index_t GEO::MeshFacetCornersStore::adjacent_facet ( index_t  c) const
inline

Gets the facet that a corner is adjacent to.

Parameters
[in]cthe corner
Returns
the facet that corner is adjacent to or NO_FACET if c is on the border

Definition at line 887 of file mesh.h.

◆ adjacent_facet_ptr() [1/2]

index_t* GEO::MeshFacetCornersStore::adjacent_facet_ptr ( index_t  c)
inline

Gets a pointer to the the facet index that a corner is adjacent to.

Parameters
[in]cthe corner
Returns
a pointer to the the facet index that corner is adjacent to.

Definition at line 912 of file mesh.h.

◆ adjacent_facet_ptr() [2/2]

const index_t* GEO::MeshFacetCornersStore::adjacent_facet_ptr ( index_t  c) const
inline

Gets a pointer to the the facet index that a corner is adjacent to.

Parameters
[in]cthe corner
Returns
a pointer to the the facet index that corner is adjacent to.

Definition at line 899 of file mesh.h.

◆ clear_store()

void GEO::MeshFacetCornersStore::clear_store ( bool  keep_attributes,
bool  keep_memory = false 
)
overrideprotectedvirtual

Removes all the elements and attributes.

Parameters
[in]keep_attributesif true, then all the existing attribute names / bindings are kept (but they are cleared). If false, they are destroyed.
[in]keep_memoryif true, then memory is kept and can be reused by subsequent mesh element creations.

Reimplemented from GEO::MeshSubElementsStore.

◆ resize_store()

void GEO::MeshFacetCornersStore::resize_store ( index_t  new_size)
overrideprotectedvirtual

Resizes this MeshSubElementsStore.

On exit, nb() == new_size, elements are created or destroyed if needed.

Parameters
[in]new_sizethe desired size

Reimplemented from GEO::MeshSubElementsStore.

◆ set_adjacent_facet()

void GEO::MeshFacetCornersStore::set_adjacent_facet ( index_t  c,
index_t  f 
)
inline

Sets the facet that a corner is adjacent to.

Parameters
[in]cthe corner
[in]fthe facet that corner is adjacent to or NO_FACET if c is on the border

Definition at line 950 of file mesh.h.

◆ set_vertex()

void GEO::MeshFacetCornersStore::set_vertex ( index_t  c,
index_t  v 
)
inline

Sets the vertex that a corner is incident to.

Parameters
[in]cthe corner
[in]vthe vertex that corner c is incident to
Precondition
v < mesh.vertices.nb()

Definition at line 923 of file mesh.h.

◆ set_vertex_no_check()

void GEO::MeshFacetCornersStore::set_vertex_no_check ( index_t  c,
index_t  v 
)
inline

Sets the vertex that a corner is incident to.

Does not check whether v is a valid vertex index. This function is useful for some algorithms that need to create/update the facets before creating the vertices.

Parameters
[in]cthe corner
[in]vthe vertex that corner c is incident to
Note
Normal uses do not call this function

Definition at line 939 of file mesh.h.

◆ vertex()

index_t GEO::MeshFacetCornersStore::vertex ( index_t  c) const
inline

Gets the vertex that a corner is incident to.

Parameters
[in]cthe corner
Returns
the vertex that corner c is incident to

Definition at line 876 of file mesh.h.

◆ vertex_index_ptr() [1/2]

index_t* GEO::MeshFacetCornersStore::vertex_index_ptr ( index_t  c)
inline

Gets a pointer to the vertex that a corner is incident to.

Parameters
[in]cthe corner
Returns
a pointer to the index of the vertex that this corner is incident to
Note
Normal uses do not call this function

Definition at line 963 of file mesh.h.

◆ vertex_index_ptr() [2/2]

const index_t* GEO::MeshFacetCornersStore::vertex_index_ptr ( index_t  c) const
inline

Gets a pointer to the vertex that a corner is incident to.

Parameters
[in]cthe corner
Returns
a pointer to the index of the vertex that this corner is incident to
Note
Normal uses do not call this function

Definition at line 975 of file mesh.h.
