Detailed Description

Interface for accessing an EffectSettings that may change asynchronously in another thread; to be used in the main thread, only.

Updates are communicated atomically both ways. The address of Get() should not be relied on as unchanging between calls.

Member Function Documentation

Flush()

virtual void EffectSettingsAccess::Flush ( )

pure virtual

Make the last Set changes "persistent" in underlying storage.

Implemented in SimpleEffectSettingsAccess, anonymous_namespace{EffectUI.cpp}::EffectSettingsAccessTee, and RealtimeEffectState::Access.

Referenced by VST3UIValidator::OnClose(), LV2Validator::OnIdle(), and VST3UIValidator::UpdateUI().

Here is the caller graph for this function:

Get()

virtual const EffectSettings & EffectSettingsAccess::Get ( )

pure virtual

Implemented in SimpleEffectSettingsAccess, anonymous_namespace{EffectUI.cpp}::EffectSettingsAccessTee, and RealtimeEffectState::Access.

Referenced by AudioUnitValidator::AudioUnitValidator(), LV2Validator::BuildPlain(), VSTEffect::BuildPlain(), LV2Validator::OnIdle(), EffectDtmf::PopulateOrExchange(), EffectEcho::PopulateOrExchange(), EffectNoise::PopulateOrExchange(), EffectReverb::PopulateOrExchange(), EffectSilence::PopulateOrExchange(), EffectToneGen::PopulateOrExchange(), EffectWahwah::PopulateOrExchange(), LV2Effect::PopulateUI(), EffectBase::Preview(), EffectTimeScale::Preview(), AudioUnitValidator::UpdateUI(), LV2Validator::UpdateUI(), and VST3UIValidator::VST3UIValidator().

Here is the caller graph for this function:

IsSameAs()

virtual bool EffectSettingsAccess::IsSameAs ( const EffectSettingsAccess &  other ) const

pure virtual

Returns

whether this and the other give access to the same settings

Implemented in SimpleEffectSettingsAccess, anonymous_namespace{EffectUI.cpp}::EffectSettingsAccessTee, and RealtimeEffectState::Access.

ModifySettings()

template<typename Function >

void EffectSettingsAccess::ModifySettings ( Function &&  function )

inline

Do a correct read-modify-write of settings.

Parameters

function

takes EffectSettings & and its return is ignored. If it throws an exception, then the settings will not be updated. Thus, a strong exception safety guarantee.
