As opposed to and , integration action traits apply only to initializable and setupable objects. They are normally used for piping other actions at the end of the current one, if the current action is completed successfully.
They are similar to the extension action traits but have a few notable differences:
Their methods are always prefixed with integrate_
.
The methods are called after the extension traits.
The methods can return a different exception type so, in case of failure, the result may be wrapped in an exception of the proper type.
The integration traits inherit different corresponding traits.
Let's use as an example the default InitializableTrait
that you can find . If you check the initialize
method, all the points above should be obvious by looking at the second elseif
statement.
A good example of an integration trait is the which automagically calls the setup
method of an object that initialized successfully and is also setupable.
