        public static void quit​(Context cx,
                        Scriptable thisObj,

      • sync

        public static Object sync​(Context cx,
                          Scriptable thisObj,
                          Object[] args,
                          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 the second argument if it is defined, or otherwise 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> spawn(function() {o.f(5);}); Thread[Thread-0,5,main] entry js> spawn(function() {o.f(5);}); Thread[Thread-1,5,main] js> exit entry exit

      • runCommand

        public static Object runCommand​(Context cx,
                                Scriptable thisObj,
                                Object[] args,
                                Function funObj)
                         throws IOException
        Execute the specified command with the given argument and options as a separate process and return the exit status of the process.

        Usage: 

         runCommand(command)
 runCommand(command, arg1, ..., argN)
 runCommand(command, arg1, ..., argN, options)
        All except the last arguments to runCommand are converted to strings and denote command name and its arguments. If the last argument is a JavaScript object, it is an option object. Otherwise it is converted to string denoting the last argument and options objects assumed to be empty. The following properties of the option object are processed:
        • args - provides an array of additional command arguments
        • env - explicit environment object. All its enumerable properties define the corresponding environment variable names.
        • input - the process input. If it is not java.io.InputStream, it is converted to string and sent to the process as its input. If not specified, no input is provided to the process.
        • output - the process output instead of java.lang.System.out. If it is not instance of java.io.OutputStream, the process output is read, converted to a string, appended to the output property value converted to string and put as the new value of the output property.
        • err - the process error output instead of java.lang.System.err. If it is not instance of java.io.OutputStream, the process error output is read, converted to a string, appended to the err property value converted to string and put as the new value of the err property.
        • dir - the working direcotry to run the commands.
        Throws:
        IOException

      • readFile

        public static Object readFile​(Context cx,
                              Scriptable thisObj,
                              Object[] args,
                              Function funObj)
                       throws IOException
        The readFile reads the given file content and convert it to a string using the specified character coding or default character coding if explicit coding argument is not given.

        Usage: 

         readFile(filePath)
 readFile(filePath, charCoding)
        The first form converts file's context to string using the default character coding.
        Throws:
        IOException

      • readUrl

        public static Object readUrl​(Context cx,
                             Scriptable thisObj,
                             Object[] args,
                             Function funObj)
                      throws IOException
        The readUrl opens connection to the given URL, read all its data and converts them to a string using the specified character coding or default character coding if explicit coding argument is not given.

        Usage: 

         readUrl(url)
 readUrl(url, charCoding)
        The first form converts file's context to string using the default charCoding.
        Throws:
        IOException
