Class TaggableRequest

java.lang.Object

java.net.http.HttpRequest

com.github.mizosoft.methanol.TaggableRequest

Direct Known Subclasses:

MutableRequest

public abstract class TaggableRequest
extends HttpRequest

An HttpRequest that can carry arbitrary values, referred to as tags. Tags can be used to carry application-specific data throughout interceptors and listeners. Tags are mapped by their type. One type cannot map to more than one tag.

A TaggableRequest also carries the BodyAdapter.Hints to be used when encoding the request body and/or decoding the response body. Hints are like tags but are meant to carry arbitrary values to adapters rather than interceptors or listeners.
