Interface PartInstanceConverterInterface

The PartInstanceConverterInterface interface is used to get, from a list of part instance ids, the corresponding geometric instance ids.

Contrary to the GeometricInstanceConverterInterface, this operation is not dependant on a WorkingSetInterface.

This conversion may be useful to change the display on some part instances, from a search query for example , since the InfiniteEngineInterface works on geometric instance ids.

The PartInstanceConverterInterface interfaces are created through the DataSessionInterface.createPartInstanceConverter method.

The list of signals the PartInstanceConverterInterface may trigger is available in the PartInstanceConverterInterfaceSignal enumeration.

The conversion mechanism is triggered through the convert method. The result is not available right away, but the event PartInstanceConverterInterfaceSignal.PartInstanceConverterReady is triggered when the result of the PartInstanceConverterInterfaceSignal is available. The result is available through the getGeometricInstanceIds function.

Warning : there may be cases when the getGeometricInstanceIds is not available such as when the PartInstanceConverterInterface is fetching data, i.e. when isRunning returns true, or when the PartInstanceConverterInterface has been cancelled, i.e. when isCancelled returns true.

A PartInstanceConverterInterface may be interrupted (cancelled) when the PartInstanceConverterInterface is fetching data and cancel is called. In such cases, the PartInstanceConverterInterfaceSignal.PartInstanceConverterCancelled signal is fired, and shortly after, PartInstanceConverterInterfaceSignal.PartInstanceConverterReady signal is fired, but getGeometricInstanceIds will return undefined. Just call convert with another (or the same) part instance ids to trigger a new retrieval.

If you call multiple times convert before receiving the PartInstanceConverterInterfaceSignal.PartInstanceConverterReady, only one PartInstanceConverterInterfaceSignal.PartInstanceConverterReady will be sent with the content of the last call to convert.

This interface performs the opposite operation of the GeometricInstanceConverterInterface interface.

Please make sure the destination browser supports promises before using async calls.
