_getCellType()

CellMerger::_Type Arcane::mesh::CellMerger::_getCellType ( const Integer & internal_cell_type ) const

private

Determines the cell _Type based on its "ItemInternal" type.

Parameters

internal_cell_type

the "ItemInternal" type

Returns

the cell _Type

_promoteType()

CellMerger::_Type Arcane::mesh::CellMerger::_promoteType ( const _Type & t1, const _Type & t2 ) const

private

Determines the cell type resulting from the merging of two given types.

Note

at this stage, nothing guarantees that the merge will succeed

Parameters

t1	the first type
t2	the second type

Returns

the type of the merged cell

_typeName()

String Arcane::mesh::CellMerger::_typeName ( const _Type & t ) const

private

Returns the name associated with the cell type.

Parameters

t

the type

Returns

the string containing the name.

Here is the caller graph for this function:

getCell()

Cell Arcane::mesh::CellMerger::getCell	(	Cell	i_cell_1,
		Cell	i_cell_2 )

Returns the cell used by the cell after merging.

Parameters

i_cell_1	a pointer to the first cell
i_cell_2	a pointer to the second cell

Returns

the new cell.

Note

the new cell is always either i_cell_1 or i_cell_2. No memory allocation is performed.

getItemInternal()

ItemInternal * Arcane::mesh::CellMerger::getItemInternal	(	ItemInternal *	i_cell_1,
		ItemInternal *	i_cell_2 )

Returns the ItemInternal used by the cell after merging.

Parameters

i_cell_1	a pointer to the first cell
i_cell_2	a pointer to the second cell

Returns

a pointer to the new cell.

Note

the new pointer is always either i_cell_1 or i_cell_2. No memory allocation is performed.

merge()

void Arcane::mesh::CellMerger::merge	(	Cell	i_cell_1,
		Cell	i_cell_2 )

Merges the two cells i_cell_1 and i_cell_2.

Parameters

i_cell_1	a pointer to the first cell
i_cell_2	a pointer to the second cell

Note

the merge is always performed in i_cell_1, i_cell_2 becomes a flattened cell that will be destroyed later.
