Method Summary

Modifier and Type	Method and Description
static java.lang.Object	bindings(org.mozilla.javascript.Context cx, org.mozilla.javascript.Scriptable thisObj, java.lang.Object[] args, org.mozilla.javascript.Function funObj) The bindings function takes a JavaScript scope object of type ExternalScriptable and returns the underlying Bindings instance.
static java.lang.Object	scope(org.mozilla.javascript.Context cx, org.mozilla.javascript.Scriptable thisObj, java.lang.Object[] args, org.mozilla.javascript.Function funObj) The scope function creates a new JavaScript scope object with given Bindings object as backing store.
static java.lang.Object	sync(org.mozilla.javascript.Context cx, org.mozilla.javascript.Scriptable thisObj, java.lang.Object[] args, org.mozilla.javascript.Function funObj) The sync function creates a synchronized function (in the sense of a Java synchronized method) from an existing function.

Method Detail

bindings

public static java.lang.Object bindings(org.mozilla.javascript.Context cx,
                                        org.mozilla.javascript.Scriptable thisObj,
                                        java.lang.Object[] args,
                                        org.mozilla.javascript.Function funObj)

The bindings function takes a JavaScript scope object of type ExternalScriptable and returns the underlying Bindings instance. var page = scope(pageBindings); with (page) { // code that uses page scope } var b = bindings(page); // operate on bindings here.

scope

public static java.lang.Object scope(org.mozilla.javascript.Context cx,
                                     org.mozilla.javascript.Scriptable thisObj,
                                     java.lang.Object[] args,
                                     org.mozilla.javascript.Function funObj)

The scope function creates a new JavaScript scope object with given Bindings object as backing store. This can be used to create a script scope based on arbitrary Bindings instance. For example, in webapp scenario, a 'page' level Bindings instance may be wrapped as a scope and code can be run in JavaScripe 'with' statement: var page = scope(pageBindings); with (page) { // code that uses page scope }

sync

public static java.lang.Object sync(org.mozilla.javascript.Context cx,
                                    org.mozilla.javascript.Scriptable thisObj,
                                    java.lang.Object[] args,
                                    org.mozilla.javascript.Function funObj)

The sync function creates a synchronized function (in the sense of a Java synchronized method) from an existing function. The new function synchronizes on the this object of its invocation. js> var o = { f : sync(function(x) { print("entry"); Packages.java.lang.Thread.sleep(x*1000); print("exit"); })}; js> thread(function() {o.f(5);}); entry js> thread(function() {o.f(5);}); js> exit entry exit
