Class CursorResetInterceptor

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.streaming.CursorResetInterceptor

All Implemented Interfaces:

org.mule.runtime.extension.api.runtime.operation.Interceptor<org.mule.runtime.api.meta.model.operation.OperationModel>

public class CursorResetInterceptor
extends Object
implements org.mule.runtime.extension.api.runtime.operation.Interceptor<org.mule.runtime.api.meta.model.operation.OperationModel>

This interceptor tracks all the cursors that were resolved as parameters of a given operation execution and the position they were in before the execution. If the operation fails with a ConnectionException, then the SDK will attempt to reconnect. This interceptor makes sure that all those cursors are set back on their original positions before the retry is attempted, since otherwise, the stream would be corrupted and the repeatable promise broken.
