EngineCallBacksDefault.queryInterrupt

default implementation of queryInterrupt

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

boolean queryInterrupt( Object data ) throws MapleException

Parameters

data

-

arbitrary data that was passed to the Engine constructor

Description

• 

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

• 

This default implementation always returns false, thus the Maple engine will never be interrupted.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

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

    {

    String mapleArgs[];

    Engine engine;

    Algebraic a;

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    while ( true )

    {

        a = engine.evaluate( "Array( 1..10^5 ):" );

        a.dispose();

    }

    }

}

This example code will never interrupt the Maple engine because the queryInterrupt CallBack always returns false.
