Base class for mesh sub-element storage.
Sub-elements are those that cannot exist independently (such as MeshFacetCorner, MeshCellCorner and MeshCellFacet).
GEO::MeshSubElementsStore::MeshSubElementsStore | ( | Mesh & | mesh | ) |
Constructs a new MeshSubElementStore.
[in] | mesh | a reference to the mesh this MeshElementStore belongs to. |
|
inlineprotected |
Makes the size of the store tightly match the number of the elements.
When elements are created one by one, the system may allocate more memory than necessary, to amortize the cost of container reallocation. Once the object is constructed, this function may be called to release the memory that was not used.

inline |
|
inline |
|
protectedvirtual |
Removes all the elements and attributes.
[in] | keep_attributes | if true, then all the existing attribute names / bindings are kept (but they are cleared). If false, they are destroyed. |
[in] | keep_memory | if true, then memory is kept and can be reused by subsequent mesh element creations. |
Reimplemented in GEO::MeshCellFacetsStore, GEO::MeshCellCornersStore, GEO::MeshCellsStore, GEO::MeshFacetCornersStore, GEO::MeshFacetsStore, GEO::MeshEdges, and GEO::MeshVertices.
|
inlineprotected |
Copies a MeshSubElementsStore into this one.
[in] | rhs | a const reference to the MeshSubElementsStore to be copied. |
[in] | copy_attributes | if true, copies also the attributes, else attributes are cleared. |

protectedvirtual |
Resizes this MeshSubElementsStore.
On exit, nb() == new_size, elements are created or destroyed if needed.
[in] | new_size | the desired size |
Reimplemented in GEO::MeshCellFacetsStore, GEO::MeshCellCornersStore, GEO::MeshCellsStore, GEO::MeshFacetCornersStore, GEO::MeshFacetsStore, GEO::MeshEdges, and GEO::MeshVertices.
