Interface RhinoHostObjectProvider

  • public interface RhinoHostObjectProvider
    The RhinoHostObjectProvider defines the service interface to inject additional ECMAScript host objects as well as to make classes and packages known.

    • Method Detail

      • getHostObjectClasses

        Class<? extends org.mozilla.javascript.Scriptable>[] getHostObjectClasses()
        Returns an array of classes implementing the Rhino Scriptable interface. These classes will be registered with the global scope as host objects and may then be used in any server-side ECMAScript scripts.
        Returns:
        the host object classes; may return null instead of an empty array for implementations that do not provide any host objects

      • getImportedClasses

        Class<?>[] getImportedClasses()
        Returns an array of classes, which are transparently converted into ECMAScript host objects in the global scope.

        Normally any Java class may be used within ECMAScript but it must be prefixed with Packages and the fully qualified package name of the class. For example to use the class org.slf4j.Log in an ECMAScript it must be noted as Packages.org.slf4j.Log. By registering the org.slf4j.Log as an imported class, it may simply be referred to as Log (provided there is no other object of that name, of course).

        Returns:
        the imported classes; may return null instead of an empty array for implementations that do not import any classes

      • getImportedPackages

        String[] getImportedPackages()
        Returns an array of Java package names to define name spaces in the global scope.

        Normally any Java class may be used within ECMAScript but it must be prefixed with Packages and the fully qualified package name of the class. For example to use the class org.slf4j.Log in an ECMAScript it must be noted as Packages.org.slf4j.Log. By registering the org.slf4j package as an imported package, it may simply be referred to as Log (provided there is no other object of that name, of course).

        The difference between importing packages and importing classes is that for a package import to work, the package must be visible to the ECMAScript bundle.

        Implementations may return null instead of an empty array if they do not provide any package names.

        Returns:
        the imported packages; may return null instead of an empty array for implementations that do import any packages
