This structure is private to the implementation.
| t8_shmem_array_t t8_forest::element_offsets |
If partitioned, for each process the global index of its first element.
Since it is memory consuming, it is usually only constructed when needed and otherwise unallocated.
| t8_gloidx_t t8_forest::first_local_tree |
The global index of the first local tree on this process.
If first_local_tree is larger than last_local_tree then this processor/forest is empty. See https://github.com/DLR-AMR/t8code/wiki/Tree-indexing
| int t8_forest::ghost_algorithm |
Controls the algorithm used for ghost.
1 = balanced only. 2 = also unbalanced 3 = top-down search and unbalanced.
| t8_forest_ghost_t t8_forest::ghosts |
If not NULL, the ghost elements.
| t8_shmem_array_t t8_forest::global_first_desc |
If partitioned, for each process the linear id (at maxlevel) of its first element's first descendant.
t8_element_set_linear_id. Stores 0 for empty processes. Since it is memory consuming, it is usually only constructed when needed and otherwise unallocated.
| t8_gloidx_t t8_forest::last_local_tree |
The global index of the last local tree on this process.
-1 if this processor is empty.
| t8_forest_adapt_t t8_forest::set_adapt_fn |
refinement and coarsen function.
Called when from_method is set to T8_FOREST_FROM_ADAPT.
| int t8_forest::set_balance |
Flag to decide whether to forest will be balance in t8_forest_commit.
See t8_forest_set_balance. If 0, no balance. If 1 balance with repartitioning, if 2 balance without repartitioning,
| t8_shmem_array_t t8_forest::tree_offsets |
If partitioned for each process the global index of its first local tree or -(first local tree) - 1 if the first tree on that process is shared.
Since this is memory consuming we only construct it when needed. This array follows the same logic as tree_offsets in t8_cmesh_t
| void* t8_forest::user_data |
Pointer for arbitrary user data.
| void(* t8_forest::user_function) () |
Pointer for arbitrary user function.
