class	_FakeGenerator
	Minimal stand-in for peano4.api.datamodel.PatchToDoubleArrayWithSmartPointer: derive_load_store_compute_flag() only ever needs somewhere to write load_store_compute_flag to. More...

class	_FakeGridSelector
	Stand-in for a peano4.api.toolbox.GridSelector with one distinct guard per kind, so tests can tell which routine was used. More...

class	_FakeSubmodel
	Minimal stand-in for a peano4.api.datamodel.Patch, with a generator attribute like the real thing has. More...
