Algebraic.isDisposed - checks to see if the Algebraic object has been disposed
Calling Sequence
boolean isDisposed() throws MapleException
Description
The isDisposed function returns true if the current Algebraic object had its dispose method called, otherwise it returns false.
If the isDisposed function returns true, it is an error to attempt to call any member function of the Algebraic object except for isDisposed.
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 a1, a2;
mapleArgs = new String[1];
mapleArgs[0] = "java";
engine = new Engine( mapleArgs, new EngineCallBacksDefault(),
null, null );
a1 = engine.evaluate( "Array( 1..10^6 ):" );
if ( a1.isDisposed() )
System.out.println( "Disposed" );
}
else
System.out.println( "Not Disposed" );
a1.dispose();
Executing this code should produce the following output.
Not Disposed
Disposed
