State.restore

void restore(Instance instance,  LilvSetPortValueFunc setValue,  void *  userData,  StateFlags flags,
       const(LV2_Feature *) *  features =  null)

@nogc nothrow

Restore this state onto a plugin instance. Low overhead C callback version which is potentially real-time safe.

Parameters

`instance`	Target instance (may be null if only port values are applied via setValue)
`setValue`	Callback for port values (may be null)
`userData`	Passed to setValue
`flags`	LV2_State_Flags
`features`	Optional null-terminated feature array for the plugin's restore

void restore(Instance instance, SetPortValueDelegate setValueDg, StateFlags flags, Feature[] features = null)

Restore this state onto a plugin instance. Uses a delegate instead of a C callback and dynamic array of Feature structures which may result in GC allocation and is NOT real-time safe.

Parameters

`instance`	Target instance (may be null if only port values are applied via setValue)
`setValueDg`	Delegate callback for port values (may be null)
`flags`	Values from StateFlags (IsPod, IsPortable, IsNative)
`features`	Optional array of Feature structures for the plugin restore
