Constructor Detail

ProcessorTracingInterceptor

public ProcessorTracingInterceptor(MuleNotificationProcessor muleNotificationProcessor,
                                   org.mule.runtime.api.component.location.ConfigurationComponentLocator configurationComponentLocator)

configurationComponentLocator - to locate mule components

Method Detail

before

public void before(org.mule.runtime.api.component.location.ComponentLocation location,
                   Map<String,org.mule.runtime.api.interception.ProcessorParameterValue> parameters,
                   org.mule.runtime.api.interception.InterceptionEvent event)

Specified by:

before in interface org.mule.runtime.api.interception.ProcessorInterceptor

after

public void after(org.mule.runtime.api.component.location.ComponentLocation location,
                  org.mule.runtime.api.interception.InterceptionEvent event,
                  Optional<Throwable> thrown)

Specified by:

after in interface org.mule.runtime.api.interception.ProcessorInterceptor

around

public CompletableFuture<org.mule.runtime.api.interception.InterceptionEvent> around(org.mule.runtime.api.component.location.ComponentLocation location,
                                                                                     Map<String,org.mule.runtime.api.interception.ProcessorParameterValue> parameters,
                                                                                     org.mule.runtime.api.interception.InterceptionEvent event,
                                                                                     org.mule.runtime.api.interception.InterceptionAction action)

NOTE: Without this #around method, the context variable set in #before do not reflect in final event passed to the intercepted processor.

Specified by:

around in interface org.mule.runtime.api.interception.ProcessorInterceptor

Parameters:

location - the location and identification properties of the intercepted component in the mule app configuration.

parameters - the parameters of the component as defined in the configuration. All the values are lazily evaluated so they will be calculated when ProcessorParameterValue.resolveValue() method gets invoked.

event - an object that contains the state of the event to be sent to the component. It may be modified by calling its mutator methods.

action - when something other than continuing the interception is desired, the corresponding method on this object must be called. The methods on this object return a CompletableFuture that may be used to return from this method.

Returns:

a non-null CompletableFuture<InterceptionEvent>
