EngineCallBacksDefault.statusCallBack - default implementation of statusCallBack
Calling Sequence
void statusCallBack( Object data, long bytesUsed, long bytesAlloc, double cputime ) throws MapleException
Parameters
data
-
arbitrary data that was passed to the Engine constructor
bytesUsed
number of bytes of memory used by the Maple engine
bytesAlloc
number of bytes of memory allocated from the system
cputime
number of seconds of CPU time used by the Maple engine
Description
statusCallBack is a member function of the com.maplesoft.openmaple.EngineCallBacksDefault class. This class implements the EngineCallBacks interface.
This default implementation builds a string from the resource usage information and passes it to the textCallBack function with tag MAPLE_TEXT_STATUS. For more information on tags, see EngineCallBacks.
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( "appendto( \file1\ );" );
}
catch ( MapleException me )
System.out.println( me.getMessage() );
Executing this code produces the following output.
Error, redirection was not implemented by the application
