- trait Stage extends Handler
A special type of play.api.mvc.Handler which allows custom logic to be inserted during handling.
A special type of play.api.mvc.Handler which allows custom logic to be inserted during handling. A
Stage
accepts aRequestHeader
then returns a newRequestHeader
along with the nextHandler
to use during request handling. The next handler could be a terminalHandler
like an EssentialAction, but it could also be anotherStage
. This means it's possible to chains ofStage
s that should each be executed in turn. To automatically execute allStage
s you can call play.api.mvc.Handler.applyStages.
