Detailed Description

ORDERED registry of the System blocks + state marshaling helpers.

See contract above (OWNS BlockState + the vector; EXPOSES index/find + copy/write_state; DOES NOT OWN the domain/aux/Poisson).

Member Typedef Documentation

◆ CellConvert

using pops::SystemBlockStore::CellConvert = std::function<void(const double* in, double* out)>

Type-erase of the POINTWISE (one cell) cons <-> prim conversion of a block: in/out are arrays of ncomp doubles.

SAME type as System::CellConvert (identical std::function): assignment from set_block_conversion / native_loader stays a trivial move.

Member Function Documentation

◆ copy_comp0()

std::vector< double > pops::SystemBlockStore::copy_comp0 ( const MultiFab &  mf ) const

inline

Copies component 0 of fab(0) (density) in row-major (j slow, i fast).

device_fence beforehand: the marshaling reads the host, so the device must have finished writing U.

Here is the call graph for this function:

◆ copy_state()

std::vector< double > pops::SystemBlockStore::copy_state ( const MultiFab &  mf, int  ncomp  ) const

inline

Copies the ncomp components of fab(0) in component-major layout (c slow, then j, then i).

Here is the call graph for this function:

◆ find() [1/2]

BlockState & pops::SystemBlockStore::find ( const std::string &  name )

inline

Reference to block name (for writing).

Exceptions

std::runtime_error

"System: bloc inconnu '...'".

◆ find() [2/2]

const BlockState & pops::SystemBlockStore::find ( const std::string &  name ) const

inline

Reference to block name (for reading).

Exceptions

std::runtime_error

"System: bloc inconnu '...'".

◆ index()

int pops::SystemBlockStore::index ( const std::string &  name ) const

inline

0-based index of block name (insertion order).

Exceptions

std::runtime_error

if unknown.

◆ names()

std::vector< std::string > pops::SystemBlockStore::names ( ) const

inline

Block names, in insertion order (UNIQUE source: all add paths appear here).

◆ size()

int pops::SystemBlockStore::size ( ) const

inline

Number of registered blocks.

◆ write_state()

void pops::SystemBlockStore::write_state ( MultiFab &  mf, int  ncomp, const std::vector< double > &  in  )

inline

Writes the ncomp components into fab(0) from a component-major buffer (same layout as copy_state).

Exceptions

std::runtime_error

"System::set_state: taille != ncomp*n*n" if the size does not match ncomp*nx*ny (message unchanged).

Here is the call graph for this function:

Member Data Documentation

◆ blocks

std::vector<BlockState> pops::SystemBlockStore::blocks

ORDERED registry of the blocks (UNIQUE source of truth).

PUBLIC: Impl aliases it as sp for the already-extracted templates (SystemFieldSolver / SystemStepper / native_loader) that iterate owner_->sp.
