Detailed Description

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

Classical double-buffer synchronous update.

Reads the current frame, computes every cell's next state, writes into the next-buffer, then swaps the two buffers in O(1). Equivalent to the Phase 3 Synchronous_Engine; provided as a strategy so the Phase 13 engine can pick it up like any other scheme.

Template Parameters

Order

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

Member Function Documentation

apply()

template<typename Order = RowMajor>

template<typename Engine , typename Rule >

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

inline

Execute one synchronous step.

Template Parameters

Engine	engine type providing current_buffer(), next_buffer(), swap_buffers(), 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.
