Scala.js 0.6.25 - scala.scalajs.js.annotation

class ExposedJSMember extends Annotation with StaticAnnotation

IMPLEMENTATION DETAIL: Marks the annotated member as exposed as a JS member.

This annotation is added automatically by the compiler to all public and protected members of a Scala.js-defined JS class. It marks the annotated member as being exposed as a JS member.

Do not use this annotation yourself.

class JSBracketAccess extends Annotation with StaticAnnotation

Marks the annotated method as representing bracket access in JavaScript.

See also: Calling JavaScript from Scala.js

class JSBracketCall extends Annotation with StaticAnnotation

Marks the annotated method as representing bracket call in JavaScript.

See also: Calling JavaScript from Scala.js

class JSExport extends Annotation with StaticAnnotation

Specifies that the given entity should be exported for use in raw JS.

Annotations: @field() @getter() @setter()
See also: Export Scala.js APIs to JavaScript

class JSExportAll extends Annotation with StaticAnnotation

Exports all public members directly defined in a class / object.

Strictly equivalent to putting JSExport on every public member. Note: You are allowed to export protected members, but you'll have to do this explicitly on each member.

See also: Export Scala.js APIs to JavaScript

class JSExportDescendentClasses extends Annotation with StaticAnnotation

Specifies that all the concrete classes extending the annotated class or should have all their public constructors exported for use in raw JS.

Specifies that all the concrete classes extending the annotated class or should have all their public constructors exported for use in raw JS. The constructors exported this way are exported under their fully qualified name.

See also: Export Scala.js APIs to JavaScript

class JSExportDescendentObjects extends Annotation with StaticAnnotation

Specifies that all the objects extending the annotated class or trait should be exported for use in raw JS.

Specifies that all the objects extending the annotated class or trait should be exported for use in raw JS. Note that objects exported this way are exported under their fully qualified name.

See also: Export Scala.js APIs to JavaScript

class JSExportStatic extends Annotation with StaticAnnotation

Specifies that the annotated member should be exported as a JavaScript static member of the companion class.

This annotation may only be used on members of a Scala object whose companion class is a Scala.js-defined JavaScript class. The annotated member will be available as a static member of the companion class.

class JSExportTopLevel extends Annotation with StaticAnnotation

Specifies that the given member should be exported to the top level of the module.

Annotations: @field() @getter() @setter()
See also: Export Scala.js APIs to JavaScript

class JSGlobal extends Annotation with StaticAnnotation

Marks the annotated class or object as being a member of the JavaScript global scope.

The annotated class/object must also be annotated with @js.native, and therefore extend js.Any.

Given:

@js.native
@JSGlobal
class Foo extends js.Object

@js.native
@JSGlobal("Foobar")
object Bar extends js.Object

@js.native
@JSGlobal("Lib.Babar")
class Babar extends js.Object

The following mappings apply (global denotes the global scope):

Scala.js                | JavaScript
------------------------+------------------
new Foo()               | new global.Foo()
Bar                     | global.Foobar
js.constructorOf[Babar] | global.Lib.Babar

class JSGlobalScope extends Annotation with StaticAnnotation

Marks the annotated object as representing the JavaScript global scope.

This is particularly useful to model top-level functions and fields that are in the JavaScript global scope. They can be declared inside an object annotated with @JSGlobalScope.

See also: Calling JavaScript from Scala.js

class JSImport extends Annotation with StaticAnnotation

Marks the annotated class or object as imported from another JS module.

Intuitively, this corresponds to ECMAScript import directives. See the documentation of the various constructors.

@JSImport is not compatible with the jsDependencies mechanism offered by the Scala.js sbt plugin. You are responsible for resolving and/or bundling the JavaScript modules that you are importing using other mechanisms.

class JSName extends Annotation with StaticAnnotation

Specifies the JavaScript name of an entity.

Annotations: @field() @getter() @setter()
See also: Calling JavaScript from Scala.js

class JavaDefaultMethod extends Annotation with StaticAnnotation

Mark a concrete trait method as a Java default method.

This annotation can be used on concrete trait methods to mark them as Java default methods. This should be used *only* to implement interfaces of the JDK that have default methods in Java.

Otherwise using this annotation is unspecified.

class RawJSType extends Annotation with StaticAnnotation

Marks the annotated class, trait or object as a raw JavaScript type.

This annotation is added automatically by the compiler to all classes, traits and objects inheriting directly or indirectly from scala.scalajs.js.Any. It marks the annotated entity as being a raw JavaScript type, i.e., one that represents type information for an entity defined in JavaScript code.

Do not use this annotation yourself.

class SJSDefinedAnonymousClass extends Annotation

IMPLEMENTATION DETAIL: Marks anonymous Scala.js-defined JS classes.

This annotation is added automatically by the compiler to Scala.js defined anonymous classes.

Do not use this annotation yourself.

class ScalaJSDefined extends Annotation with StaticAnnotation

Marks the annotated class as a Scala.js-defined JavaScript class.

This annotation may only be used on a class extending js.Any.

class WasPublicBeforeTyper extends Annotation

IMPLEMENTATION DETAIL: Marks public members of anonymous classes before typer.

This annotation is added automatically by the compiler to all public members of anonymous classes.

Do not use this annotation yourself.

class JSExportNamed extends Annotation with StaticAnnotation

Exports the given method to JavaScript with named parameters.

It can then be called like this:

obj.foo({
  param1: value1
  param2: value2
  param7: value3
});

Note that named exports don't support overloading. Therefore the following will fail:

class A {
  @JSExportNamed
  def a(foo: Int) = foo + 1
  @JSExportNamed
  def a(bar: String) = "Hello " + bar
}

As of Scala.js 0.6.11, @JSExportNamed is deprecated without direct replacement (see https://github.com/scala-js/scala-js/issues/2442). You should take a single parameter of a JS type and decompose it yourself. For example, instead of

class A {
  @JSExportNamed
  def foo(a: Int, b: String, c: Boolean = false): Unit = {
    // do something with a, b, c
  }
}

you should write:

trait FooOptions extends js.Object {
  val a: Int
  val b: String
  val c: js.UndefOr[Boolean]
}

class A {
  @JSExport
  def foo(options: FooOptions): Unit = {
    val a = options.a
    val b = options.b
    val c = options.c.getOrElse(false)
    // do something with a, b, c
  }
}

Annotations: @deprecated
Deprecated: (Since version 0.6.11)

class JSFullName extends Annotation with StaticAnnotation

IMPLEMENTATION DETAIL: Saves the fully qualified JS name of a symbol.

This annotation was used prior to Scala.js 0.6.13. It is only kept for backwards binary compatibility, and should not be used anymore.

Do not use this annotation yourself.

Annotations: @deprecated
Deprecated: (Since version 0.6.13) Replaced by internal.JSNativeLoadSpec.
