The member argument must be either a java.lang.reflect.Method + * or a java.lang.reflect.Constructor and must match one of two forms.

+ * + * The first form is a member with zero or more parameters + * of the following types: Object, String, boolean, Scriptable, + * int, or double. The Long type is not supported + * because the double representation of a long (which is the + * EMCA-mandated storage type for Numbers) may lose precision. + * If the member is a Method, the return value must be void or one + * of the types allowed for parameters.

+ * + * The runtime will perform appropriate conversions based + * upon the type of the parameter. A parameter type of + * Object specifies that no conversions are to be done. A parameter + * of type String will use Context.toString to convert arguments. + * Similarly, parameters of type double, boolean, and Scriptable + * will cause Context.toNumber, Context.toBoolean, and + * Context.toObject, respectively, to be called.

+ * + * If the method is not static, the Java 'this' value will + * correspond to the JavaScript 'this' value. Any attempt + * to call the function with a 'this' value that is not + * of the right Java type will result in an error.

+ * + * The second form is the variable arguments (or "varargs") + * form. If the FunctionObject will be used as a constructor, + * the member must have the following parameters + * 

+     *      (Context cx, Object[] args, Function ctorObj,
+     *       boolean inNewExpr)
+ * and if it is a Method, be static and return an Object result.

+ * + * Otherwise, if the FunctionObject will not be used to define a + * constructor, the member must be a static Method with parameters + * (Context cx, Scriptable thisObj, Object[] args, + * Function funObj) + * 

+     * and an Object result.

+     *
+     * When the function varargs form is called as part of a function call,
+     * the args parameter contains the
+     * arguments, with thisObj
+     * set to the JavaScript 'this' value. funObj
+     * is the function object for the invoked function.

+     *
+     * When the constructor varargs form is called or invoked while evaluating
+     * a new expression, args contains the
+     * arguments, ctorObj refers to this FunctionObject, and
+     * inNewExpr is true if and only if  a new
+     * expression caused the call. This supports defining a function that
+     * has different behavior when called as a constructor than when
+     * invoked as a normal function call. (For example, the Boolean
+     * constructor, when called as a function,
+     * will convert to boolean rather than creating a new object.)

+     * @param methodOrConstructor a java.lang.reflect.Method or a java.lang.reflect.Constructor

+/**
+ * Class ImporterTopLevel
+ *
+ * This class defines a ScriptableObject that can be instantiated
+ * as a top-level ("global") object to provide functionality similar
+ * to Java's "import" statement.
+ * 

+ * This class can be used to create a top-level scope using the following code:
+ * 
+ *  Scriptable scope = new ImporterTopLevel(cx);
+ * 

+ * Then JavaScript code will have access to the following methods:
+ * 
    
+ * 
  • importClass - will "import" a class by making its unqualified name
+ *                   available as a property of the top-level scope
+ * 
  • importPackage - will "import" all the classes of the package by
+ *                     searching for unqualified names as classes qualified
+ *                     by the given package.
+ * 

+ * The following code from the shell illustrates this use:
+ * 
+ * js> importClass(java.io.File)
+ * js> f = new File('help.txt')
+ * help.txt
+ * js> importPackage(java.util)
+ * js> v = new Vector()
+ * []
