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) {
        // ...
    }
}
