EngineCallBacksDefault.streamCallBack - default implementation of streamCallBack

Calling Sequence

String streamCallBack( Object data, String name, String args[] ) throws MapleException

Parameters

data

-

arbitrary data that was passed into the Engine constructor

name

-

name of the stream on which the stream call occurred, without the "INTERFACE_" prefix

args

-

array of the line printed arguments passed into the stream call

Description

• 

streamCallBack 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 streamCallBack 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( "INTERFACE_PINE( 1,2,3 );" );

    }

    catch ( MapleException me )

    {

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

    }

    }

}

Executing this code produces the following output.

Error, generic streams are not implemented by the application
