Description
Examples
List toList() throws MapleException
Set toSet() throws MapleException
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.

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
