Example 82 with CoreEvent

use of org.mule.runtime.core.api.event.CoreEvent in project mule by mulesoft.

the class CompositeSourcePolicy method processNextOperation.

/**
 * Executes the flow.
 *
 * If there's a {@link SourcePolicyParametersTransformer} provided then it will use it to convert the source response or source
 * failure response from the parameters back to a {@link Message} that can be routed through the policy chain which later will
 * be convert back to response or failure response parameters thus allowing the policy chain to modify the response.. That
 * message will be the result of the next-operation of the policy.
 *
 * If no {@link SourcePolicyParametersTransformer} is provided, then the same response from the flow is going to be routed as
 * response of the next-operation of the policy chain. In this case, the same response from the flow is going to be used to
 * generate the response or failure response for the source so the policy chain is not going to be able to modify the response
 * sent by the source.
 *
 * When the flow execution fails, it will create a {@link FlowExecutionException} instead of a regular
 * {@link MessagingException} to signal that the failure was through the the flow exception and not the policy logic.
