Class DefaultExecutionMediator<M extends org.mule.runtime.api.meta.model.ComponentModel>

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.operation.DefaultExecutionMediator<M>

All Implemented Interfaces:

ExecutionMediator<M>

public final class DefaultExecutionMediator<M extends org.mule.runtime.api.meta.model.ComponentModel>
extends Object
implements ExecutionMediator<M>

Default implementation of ExecutionMediator.

It also inspects the ConfigurationStats obtained from the ConfigurationDeclaration in the context. If the stats class implements the MutableConfigurationStats interface, then MutableConfigurationStats.addInflightOperation() and MutableConfigurationStats.discountInflightOperation() are guaranteed to be called, whatever the operation's outcome.

In case of operation failure, it will execute the Interceptor.onError(ExecutionContext, Throwable) method of all the available interceptors. If the operation fails with ConnectionException, then a retry might be attempted depending on the configured RetryPolicyTemplate. Notice that if a retry is attempted, the entire cycle of interception (before, onSuccess/interceptError, after) will be fired again.

Since:

4.0
