Application

trait Application extends AnyRef

A Play application.

Application creation is handled by the framework engine.

If you need to create an ad-hoc application, for example in case of unit testing, you can easily achieve this using:

val application = Application(new File("."), this.getClass.getClassloader, None, Play.Mode.Dev)

This will create an application using the current classloader.

  12. def getExistingFile(relativePath: String): Option[File]

    Retrieves a file relative to the application root path.

    Retrieves a file relative to the application root path. This method returns an Option[File], using None if the file was not found.

    For example, to retrieve a configuration file:

    val myConf = application.getExistingFile("conf/myConf.yml")
    relativePath

    the relative path of the file to fetch

    returns

    an existing file

  13. def getFile(relativePath: String): File

    Retrieves a file relative to the application root path.

    Retrieves a file relative to the application root path.

    For example, to retrieve a configuration file:

    val myConf = application.getFile("conf/myConf.yml")
    relativePath

    relative path of the file to fetch

    returns

    a file instance; it is not guaranteed that the file exists

  19. def plugin[T](implicit ct: ClassTag[T]): Option[T]

    Retrieves a plugin of type T.

    Retrieves a plugin of type T.

    For example, to retrieve the DBPlugin instance:

    val dbPlugin = application.plugin[DBPlugin].map(_.api).getOrElse(sys.error("problem with the plugin"))
    T

    the plugin type

    returns

    The plugin instance used by this application.

    Exceptions thrown
    Error

    if no plugins of type T are loaded by this application.

  20. def plugin[T](pluginClass: Class[T]): Option[T]

    Retrieves a plugin of type T.

    Retrieves a plugin of type T.

    For example, retrieving the DBPlugin instance:

    val dbPlugin = application.plugin(classOf[DBPlugin])
    T

    the plugin type

    pluginClass

    the plugin’s class

    returns

    the plugin instance, wrapped in an option, used by this application

    Exceptions thrown
    Error

    if no plugins of type T are loaded by this application

  21. def resource(name: String): Option[URL]

    Scans the application classloader to retrieve a resource.

    Scans the application classloader to retrieve a resource.

    For example, to retrieve a configuration file:

    val maybeConf = application.resource("conf/logger.xml")
    name

    the absolute name of the resource (from the classpath root)

    returns

    the resource URL, if found

  22. def resourceAsStream(name: String): Option[InputStream]

    Scans the application classloader to retrieve a resource’s contents as a stream.

    Scans the application classloader to retrieve a resource’s contents as a stream.

    For example, to retrieve a configuration file:

    val maybeConf = application.resourceAsStream("conf/logger.xml")
    name

    the absolute name of the resource (from the classpath root)

    returns

    a stream, if found

  23. lazy val routes: Option[core.Router.Routes]

    The router used by this application (if defined).
