EngineCallBacksDefault.queryInterrupt
default implementation of queryInterrupt
Calling Sequence
Parameters
Description
Examples
boolean queryInterrupt( Object data ) throws MapleException
data
-
arbitrary data that was passed to the Engine constructor
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.
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.
