◆ boxArray()

const BoxArray & amrex::EBFArrayBoxFactory::boxArray ( ) const

noexcept

BoxArray describing the FAB layout.

◆ clone()

EBFArrayBoxFactory * amrex::EBFArrayBoxFactory::clone ( ) const

finalvirtual

Destroy a FAB produced by this factory.

Implements amrex::FabFactory< FArrayBox >.

noexcept

Distribution mapping describing the FABs this factory allocates.

◆ faceDir()

int amrex::EBFArrayBoxFactory::faceDir ( ) const

inlinenoexcept

Face direction if this is an FC factory (-1 for CC mode).

inlinenoexcept

Cell centroid.

◆ getCutCellMask()

iMultiFab const * amrex::EBFArrayBoxFactory::getCutCellMask ( ) const

inlinenoexcept

Returns nullptr unless this level is built by EB2::addRegularCoarseLevels. One should use getMultiEBCellFlagFab for normal levels.
