Detailed Description

Multi-threaded executor that runs systems in parallel using work-stealing.

Uses an injected async::Executor reference to run a async::TaskGraph that respects ordering constraints and access-policy conflicts. The async::TaskGraph and task vector are cached across frames and cleared/rebuilt each execution.

Member Function Documentation

Execute()

void helios::ecs::MultiThreadedExecutor::Execute ( Schedule & schedule, World & world )

overridevirtual

Executes the schedule using the multi-threaded executor.

Parameters

schedule	The schedule to execute
world	The world context for system execution

Implements helios::ecs::Executor.

Definition at line 101 of file multi_threaded.cpp.

ExecuteAndWait()

void helios::ecs::MultiThreadedExecutor::ExecuteAndWait ( Schedule & schedule, World & world )

overridevirtual

Executes all systems in the schedule and blocks until completion.

Default implementation calls Execute() then Wait().

Parameters

schedule	Compiled schedule to execute
world	World to pass to each system

Reimplemented from helios::ecs::Executor.

Definition at line 106 of file multi_threaded.cpp.

defaultnoexcept

Wait()

void helios::ecs::MultiThreadedExecutor::Wait ( )

inlineoverridevirtual

Waits for the most recent Execute() to complete.

Blocks until the submitted task graph finishes.

Reimplemented from helios::ecs::Executor.
