Expseq.length - return the length of the Expseq
Calling Sequence
int length( ) throws MapleException
Description
The length function returns the number of elements that the Expseq can store.
Examples
import com.maplesoft.openmaple.*;
import com.maplesoft.externalcall.MapleException;
class Example
{
public static void main( String notused[] ) throws MapleException
String mapleArgs[];
Engine engine;
Expseq e;
mapleArgs = new String[1];
mapleArgs[0] = "java";
engine = new Engine( mapleArgs, new EngineCallBacksDefault(),
null, null );
e = (Expseq)engine.evaluate( "1,2,3:" );
System.out.println( e.length() );
e = engine.newExpseq( 4 );
e.assign( 1, engine.newNumeric( 1 ) );
e.assign( 2, engine.newNumeric( 2 ) );
e.assign( 3, engine.newNumeric( 3 ) );
e.assign( 4, engine.newNumeric( 4 ) );
e = (Expseq)e.unique();
e = (Expseq)engine.evaluate( "seq( i, i=1..100 ):" );
}
Executing this code produces the following output.
3
4
100
