Detailed Description

template<typename Order = RowMajor>
struct Aleph::CA::Sequential_Update< Order >

In-place sequential update (no double buffer).

Visits every cell in Order and writes the new value back to the same lattice. Each cell sees the partially-updated neighbourhood, which is the dynamics needed by sandpile-style relaxation models and many physics-flavoured CAs. The choice of Order materially changes the qualitative behaviour, on purpose.

Template Parameters

Order

iteration tag (RowMajor, ColumnMajor, Tile<W, H>).

apply()

template<typename Order = RowMajor>

template<typename Engine , typename Rule >

void Aleph::CA::Sequential_Update< Order >::apply ( Engine &  e, Rule &  r  ) const

inline

Execute one sequential in-place step.

Template Parameters

Engine	engine type providing current_buffer(), neighborhood() and step_count().
Rule	cell rule satisfying RuleLike<Rule, Lattice>.

Parameters

[in,out]	e	engine reference.
[in]	r	rule reference.

Exceptions

Any	exception propagated by the rule or the lattice.
