boolean isDisposed() throws MapleException
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.

class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
Algebraic 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
