Load and execute a set of JavaScript source files. | | public static void | loadClass(Context cx, Scriptable thisObj, Object[] args, Function funObj)
Load and execute a script compiled to a class file.
This method is defined as a JavaScript function.
When called as a JavaScript function, a single argument is
expected. | | static void | pipe(boolean fromProcess, InputStream from, OutputStream to)

Print the string values of its arguments. | | public static void | quit(Context cx, Scriptable thisObj, Object[] args, Function funObj)
Call embedding-specific quit action passing its argument as
int32 exit code. | | public static Object | readFile(Context cx, Scriptable thisObj, Object[] args, Function funObj)
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. | | public static Object | readUrl(Context cx, Scriptable thisObj, Object[] args, Function funObj)
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. | | static RuntimeException | reportRuntimeError(String msgId)
| | static RuntimeException | reportRuntimeError(String msgId, String msgArg)
| | public static Object | runCommand(Context cx, Scriptable thisObj, Object[] args, Function funObj)

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. | | public static void | seal(Context cx, Scriptable thisObj, Object[] args, Function funObj)
The seal function seals all supplied arguments. | | public static void | serialize(Context cx, Scriptable thisObj, Object[] args, Function funObj)
| | public void | setErr(PrintStream err)

| | public void | setOut(PrintStream out)
| | public void | setSealedStdLib(boolean value)
| | public static Object | spawn(Context cx, Scriptable thisObj, Object[] args, Function funObj)
The spawn function runs a given function or script in a different
thread. | | 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. | | public static Object | toint32(Context cx, Scriptable thisObj, Object[] args, Function funObj)
Convert the argumnet to int32 number. | | public static double | version(Context cx, Scriptable thisObj, Object[] args, Function funObj)
Get and set the language version. |
| initialized | | boolean initialized(Code) | | |
| serialVersionUID | | final static long serialVersionUID(Code) | | |
| initQuitAction | | public void initQuitAction(QuitAction quitAction)(Code) | | Set the action to call from quit().
|
| isInitialized | | public boolean isInitialized()(Code) | | |
| load | | public static void load(Context cx, Scriptable thisObj, Object[] args, Function funObj)(Code) | | Load and execute a set of JavaScript source files.
This method is defined as a JavaScript function.
|
| print | | public static Object print(Context cx, Scriptable thisObj, Object[] args, Function funObj)(Code) | | Print the string values of its arguments.
This method is defined as a JavaScript function.
Note that its arguments are of the "varargs" form, which
allows it to handle an arbitrary number of arguments
supplied to the JavaScript function.
|
| quit | | public static void quit(Context cx, Scriptable thisObj, Object[] args, Function funObj)(Code) | | Call embedding-specific quit action passing its argument as
int32 exit code.
This method is defined as a JavaScript function.
|
| readFile | | public static Object readFile(Context cx, Scriptable thisObj, Object[] args, Function funObj) throws IOException(Code) | | 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.
|
| readUrl | | public static Object readUrl(Context cx, Scriptable thisObj, Object[] args, Function funObj) throws IOException(Code) | | 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.
|
| runCommand | | public static Object runCommand(Context cx, Scriptable thisObj, Object[] args, Function funObj) throws IOException(Code) | | 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.
Te following properties of the option object are processed:
- args - provides an array of additional command arguments
- env - explicit environment object. All its enumeratable
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.

| setSealedStdLib | | public void setSealedStdLib(boolean value)(Code) | | |
| spawn | | public static Object spawn(Context cx, Scriptable thisObj, Object[] args, Function funObj)(Code) | | The spawn function runs a given function or script in a different
thread.
js> function g() { a = 7; }
js> a = 3;
3
js> spawn(g)
Thread[Thread-1,5,main]
js> a
3
|
| sync | | public static Object sync(Context cx, Scriptable thisObj, Object[] args, Function funObj)(Code) | | 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> 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
