Member Function Documentation

virtual acdk::lang::dmi::ScriptVar acdk::lang::dmi::ScriptInterpreter::call ( IN(RString) func,

acdk::lang::dmi::ScriptVarArray & args

) [inline, virtual]

Calls a script function.
Note: may not all script interpreter support this function
Parameters:

func the name of the function

args the arguments for the function

Returns:
result of the call

Reimplemented in acdk::lisp::LispInterpreter, acdk::perl::APerlInterpreter, acdk::python::PythonInterpreter, and acdk::tcl::TclInterpreter.

virtual RObject acdk::lang::dmi::ScriptInterpreter::eval ( IN(RString) code ) [pure virtual]

Evaluate the code .
On some interpreter it is equal to parse.
Parameters:

script the script to eval

Returns:
the output or result of the script fragment

Implemented in acdk::lisp::LispInterpreter, acdk::perl::APerlInterpreter, acdk::python::PythonInterpreter, and acdk::tcl::TclInterpreter.

virtual void acdk::lang::dmi::ScriptInterpreter::interactive ( IN(RCharReader) in,

IN(RCharWriter) out,

IN(RCharWriter) err

) [pure virtual]

Do debug the given Script.
May not work on all scripting languages
Parameters:

in Inputstream for users input and script

out Scripts output and users Echo output

err Error stream

Implemented in acdk::lisp::LispInterpreter.

virtual acdk::lang::dmi::ScriptVar acdk::lang::dmi::ScriptInterpreter::invoke ( IN(RObject) obj,

IN(RString) func,

acdk::lang::dmi::ScriptVarArray & args

) [inline, virtual]

Calls a script method of given object.

Parameters:

obj the 'this' object of the script, which is a wrapper to the scripting

func the name of the function

args the arguments for the function

Returns:
result of the call

Reimplemented in acdk::lisp::LispInterpreter, acdk::perl::APerlInterpreter, acdk::python::PythonInterpreter, and acdk::tcl::TclInterpreter.

virtual void acdk::lang::dmi::ScriptInterpreter::parse ( IN(RString) script ) [pure virtual]

Parse a file.
On some interpreter also execute the script.
Parameters:

script the script to parse

Implemented in acdk::lisp::LispInterpreter, acdk::perl::APerlInterpreter, acdk::python::PythonInterpreter, and acdk::tcl::TclInterpreter.

virtual void acdk::lang::dmi::ScriptInterpreter::parse ( IN(RFile) file ) [pure virtual]

Parse a file.
On some interpreter also execute the script.
Parameters:

file the file to parse

Implemented in acdk::lisp::LispInterpreter, and acdk::perl::APerlInterpreter.
