Calling Sequence

Description

Examples

Calling Sequence

List toList() throws MapleException

Set toSet() throws MapleException

Description

• 

The toList function returns a List with the contents from the Indexable expression.

• 

The toSet function returns a Set with the contents from the Indexable expression.

• 

If toList is invoked when the current Indexable is already a list or toSet is invoked when the current Indexable is already a set, then a reference to the current object is returned.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

    public static void main( String notused[] ) throws MapleException

    {

        String[] mapleArgs = { "java" };

        Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );

        Indexable ind = (Indexable)engine.evaluate( "{3,5,7,9,10}:" );

        List l = ind.toList();

        System.out.println( "Size of list result: " + l.numElements() );

        ind = (Indexable)engine.evaluate( "table([a=3,b=7,c=9,d=3,e=13]):" );

        Set s = ind.toSet();

        System.out.println( "Size of set result: " + s.numElements() );

}

Executing this code produces the following output.

Size of list result: 5

Size of set result: 4
