Calling Sequence

Description

Examples

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();

        if ( a1.isDisposed() )

        {

            System.out.println( "Disposed" );

        }

        else

        {

            System.out.println( "Not Disposed" );

        }

    }

}

Executing this code should produce the following output.

Not Disposed
