Overview

This plugin provides an add-on to allow a Route Handler to set request scoped variables which will be available to other Route Handlers.

Installation

<dependency>
    <groupId>org.spincast</groupId>
    <artifactId>spincast-plugins-variables-addon</artifactId>
    <version>0.9.52</version>

Suggested add-on

Example :

public void myHandler(AppRequestContext context) {

    // Reads a request scoped variable
    context.variables().get("someVariable");

    // Adds a new request scoped variable
    context.variables().set("newVariable", "some value");
    
    //...
}

This add-on is already installed by default on the Request Context type.
