## Detailed Description

Indicates that the plug-in could or not support Prefetch (dynamically): Vst::IPrefetchableSupport.

- [plug imp]
- [extends IComponent]
- [released: 3.6.5]
- [optional]

The plug-in should implement this interface if it needs to dynamically change between prefetchable or not. By default (without implementing this interface) the host decides in which mode the plug-in is processed. For more info about the prefetch processing mode check the ProcessModes::kPrefetch documentation.

# Example

//------------------------------------------------------------------------
tresult PLUGIN_API myPlug::getPrefetchableSupport (PrefetchableSupport& prefetchable)
{
prefetchable = kIsNeverPrefetchable;
switch (myPrefetchableMode)
{
case 0: prefetchable = kIsNeverPrefetchable; break;
case 1: prefetchable = kIsYetPrefetchable; break;
case 2: prefetchable = kIsNotYetPrefetchable; break;
}
return kResultOk;
}

## Member Function Documentation

virtual tresult getPrefetchableSupport | ( | PrefetchableSupport & | prefetchable | ) |
| pure virtual

retrieve the current prefetch support.

Use IComponentHandler::restartComponent (kPrefetchableSupportChanged) to inform the host that this support has changed.
