Annotation Interface Bind.DefaultExpression

Enclosing class:

Bind

@Retention(CLASS)
@Target(TYPE)
@Inherited
public static @interface Bind.DefaultExpression

Defines a default bind expression for a given type. When a type defines a default bind expression, specialization methods can declare bind parameters of the type without specifying a bind expression; the DSL will automatically use the default expression for the type.

Usage example:

 @Bind.DefaultExpression("get($node)")
 public final class MyLanguageContext {
     // ...
     public static MyLanguageContext get(Node node) {
         // ...
     }
 }

 abstract static class NodeWithBinding extends Node {
     abstract Object execute();

     @Specialization
     Object perform(@Bind("MyLanguageContext.get($node)") MyLanguageContext boundWithExplicitExpression,
                     @Bind MyLanguageContext boundWithDefaultExpression) {
         // ...
     }
 }
