How do they work?

Interceptors are CFCs that extend the ColdBox Interceptor class (coldbox.system.Interceptor
), implement a configuration method called configure()
, and then contain methods for the events it will listen for. All interceptors are treated as singletons in your application, so make sure they are thread safe and var scoped.
Info You can also remove the inheritance from the CFC (preferred method) and WireBox will extend the
coldbox.system.Interceptor
for you using Virtual Inheritance.
You can use CommandBox to create interceptors as well:
Interceptors can be registered in your Coldbox.cfc
configuration file using the interceptors
struct, or they can be registered manually via the system's interceptor service.
In ColdBox.cfc
:
Registered manually:
configure()
MethodThe interceptor has one important method that you can use for configuration called configure()
. This method will be called right after the interceptor gets created and injected with your interceptor properties.
Info These properties are local to the interceptor only!
As you can see on the diagram, the interceptor class is part of the ColdBox framework super type family, and thus inheriting the functionality of the framework.
