Injection DSL

The injection DSL is a domain specific language that denotes what to inject in the current placeholder: property, argument, or method via the inject annotation. This injection DSL not only can it be used via annotations but also via our mapping DSL whenever a dsl argument can be used. This DSL is constructed by joining words separated by a : colon. The first part of this string is what we will denote as the injection DSL Namespace.

inject="{namespace}:extra:extra:extra"

Property Annotation

Every property can be annotated with our injection annotations:

• inject : The injection DSL

• scope : The visibility scope to inject the dependency into. By default it injects into variables scope

BoxLang

property name="service" inject="id:MyService";

property name="TYPES" inject="id:CustomTypes" scope="this";

property name="roles" inject="id:RoleService:getRoles" scope="instance";

CFML

property name="service" inject="id:MyService";

property name="TYPES" inject="id:CustomTypes" scope="this";

property name="roles" inject="id:RoleService:getRoles" scope="instance";

Constructor Argument Annotation

You can also annotate constructor arguments with the inject annotation:

BoxLang

/**
 * @myService.inject UserService
 * @cache.inject    cachebox:default
 */
function init( required myService, required cache ){
}

CFML

/**
 * @myService.inject UserService
 * @cache.inject     cachebox:default
 */
function init( required myService, required cache ){
}

Setter Method Annotation

You can also annotate setter methods with the inject annotation to provide injections:

BoxLang

function setService( required service ) inject="UserService" {
    variables.service = arguments.service
}

CFML

function setService( required service ) inject="UserService" {
    variables.service = arguments.service;
}

WireBox offers a wide gamut of annotation namespaces you can use in your BoxLang and CFML applications and ColdBox applications. However, we took it a step further and allowed you to create your own custom DSL namespaces making your annotations come alive!
