void ~ThreadingModel ()

std::unique_ptr<ThreadingModel> CreateWithMixStrategy (MixStrategy mix_strategy, MixProfileConfig mix_profile_config)

Creates a `ThreadingModel` with a provided `MixStrategy`, which configures the behavior of

`AcquireMixDomain`, and a `MixProfileConfig`.

See `MixStrategy` for more details on possible strategies.

ExecutionDomain & FidlDomain ()

Returns the `ExecutionDomain` used to run the primary |fuchsia::media::AudioCore| FIDL

service. This domain will be valid for the lifetime of this object.

This is a single-threaded dispatcher.

ExecutionDomain & IoDomain ()

Returns the `ExecutionDomain` used to run blocking IO. This domain will be valid for the

the lifetime of this object.

This is a single-threaded dispatcher.

OwnedDomainPtr AcquireMixDomain (const std::string & name_hint)

Acquires an `ExecutionDomain` to use for mixing. The returned domain will live as long as the

returned pointer.

It is implementation defined if tasks will still execute after the returned `OwnedDomainPtr` is

released; for shared dispatcher implementations these tasks will still run, while

implementations that provide a unique dispatcher may choose to immediately shutdown the loop in

response to the `OwnedDomainPtr` being released.

This is a single-threaded dispatcher.

void RunAndJoinAllThreads ()

Runs all the dispatchers. When the message loop backing |FidlDomain()| exits, the remaining

domains will all be shutdown.

When this method returns, all threads will be joined and all dispatchers stopped.

void Quit ()

Shuts down all `ExecutionDomains` provided by this `ThreadingModel`, causing

`RunAndJoinAllThreads` to eventually return.

This posts the quit operation to all message loops managed by this object, meaning all

currently runnable tasks in each loop will have an opportunity to run before the loop exits.
