Calling Sequence

String readlineCallBack( Object data, boolean debug ) throws MapleException

Parameters

arbitrary data that was passed to the Engine constructor

debug

true if readline was called from the debugger

Description

• 

readlineCallBack is a member function of the com.maplesoft.openmaple.EngineCallBacksDefault class.  This class implements the EngineCallBacks interface.

• 

This default implementation raises a MapleException stating that readlineCallBack is not implemented.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

    public static void main( String notused[] ) throws MapleException

    {

    String mapleArgs[];

    Engine engine;

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

    engine = new Engine( mapleArgs, new EngineCallBacksDefault(),

        null, null );

    try

    {

        engine.evaluate( "readline();" );

    }

    catch ( MapleException me )

    {

        System.out.println( me.getMessage() );

    }

    }

}

Executing this code produces the following output.
