InteractiveInterpreter

public InteractiveInterpreter()
Create a new Interpreter with an empty dictionary

InteractiveInterpreter

public InteractiveInterpreter(PyObject locals)
Create a new interpreter with the given dictionary to use as its namespace
Parameters:

InteractiveInterpreter

public InteractiveInterpreter(PyObject locals,
                              PySystemState systemState)

Method Details

interrupt

public void interrupt(ThreadState ts)
Pause the current code, sneak an exception raiser into sys.trace_func, and then continue the code hoping that Jython will get control to do the break;

resetbuffer

public void resetbuffer()

runcode

public void runcode(PyObject code)
execute a code object. When an exception occurs, self.showtraceback() is called to display a traceback. All exceptions are caught except SystemExit, which is reraised. A note about KeyboardInterrupt: this exception may occur elsewhere in this code, and may not always be caught. The caller should be prepared to deal with it.

runsource

public boolean runsource(String source)
Compile and run some source in the interpreter. Arguments are as for compile_command(). One several things can happen: 1) The input is incorrect; compile_command() raised an exception (SyntaxError or OverflowError). A syntax traceback will be printed by calling the showsyntaxerror() method. 2) The input is incomplete, and more input is required; compile_command() returned None. Nothing happens. 3) The input is complete; compile_command() returned a code object. The code is executed by calling self.runcode() (which also handles run-time exceptions, except for SystemExit). The return value is 1 in case 2, 0 in the other cases (unless an exception is raised). The return value can be used to decide whether to use sys.ps1 or sys.ps2 to prompt the next line.
