LongRTable.assign
assign a long to an element of the LongRTable
Calling Sequence
Parameters
Description
Examples
void assign( int index[], long val ) throws MapleException
index
-
index of the entry to assign
val
value to assign to the list
The assign function assigns the Java long val into the element of the LongRTable indexed by index.
The index parameter is an array of integers, one for each dimension of the LongRTable. Each integer must be within the bounds determined by lowerBound and upperBound. The index for dimension i is stored in the array at position i−1.
As RTables do not have unique representations, elements of an RTable can be assigned to any time.

class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
LongRTable a1 = (LongRTable)engine.evaluate( "Array( 1..2, 1..2, [[2^40,2^45],[2^50,2^55]], datatype=integer[8]):" );
int[] index = new int[2];
long e = (long)Math.pow( 3, 30 );
index[0] = 1;
index[1] = 1;
a1.assign( index, e );
e = (long)Math.pow( 3, 31 );
index[0] = 2;
e = (long)Math.pow( 3, 32 );
index[1] = 2;
e = (long)Math.pow( 3, 33 );
System.out.println( a1 );
}
Executing this code produces the following output.
Array(1..2, 1..2, [[205891132094649,1853020188851841],[617673396283947,5559060566555523]], datatype = integer[8], storage = rectangular, order = Fortran_order)
