Interface ProcessorInterceptorFactory

All Superinterfaces:

Supplier<ProcessorInterceptor>

public interface ProcessorInterceptorFactory
extends Supplier<ProcessorInterceptor>

Abstract Factory for creating ProcessorInterceptor instances.

Implementations may have fields annotated with @Inject, which will be resolved before attempting to call Supplier.get().

Field Detail

INTERCEPTORS_ORDER_REGISTRY_KEY

static final String INTERCEPTORS_ORDER_REGISTRY_KEY

By making a ProcessorInterceptorFactory.ProcessorInterceptorOrder available in the Registry with this key, the order in which the ProcessorInterceptorFactories products will be applied to the applicable components. can be customized.

For each factory, its fully qualified class name will be obtained and matched against the passed packagesOrder to sort the factories. In the case there is more than one factory with a package name prefix, the order in which they were added will be kept.

Assuming this is called with parameters ("org.package", "com.plugin"), and the following factories have been added through #addInterceptorFactory(ProcessorInterceptorFactory) (in this order):

1. com.plugin.SomeInterceptor
2. org.mule.MuleInterceptor
3. org.package.logging.LoggerInterceptor
4. com.plugin.SomeOtherInterceptor
5. org.mule.OtherMuleInterceptor

Those factories will be sorted, when obtained through #getInterceptorFactories() like this:

1. org.package.logging.LoggerInterceptor
2. com.plugin.SomeInterceptor
3. com.plugin.SomeOtherInterceptor
4. org.mule.MuleInterceptor
5. org.mule.OtherMuleInterceptor

Method Detail

intercept

default boolean intercept(ComponentLocation location)

Determines if a ProcessorInterceptor shall be created by this factory to be applied to a component based on some of its attributes.

Parameters:

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

Returns:

true if this handler must be applied to the component with the provided parameters, false otherwise.
