ByteRTable.assign - assign a byte into an element of the ByteRTable

Calling Sequence

void assign( int index[], byte val ) throws MapleException

Parameters

index

-

index of the entry to assign

val

-

value to assign into the list

Description

• 

The assign function assigns the Java byte val into the element of the ByteRTable indexed by index.

• 

index is an array of integers, one for each dimension of the ByteRTable.  Each integer must be within the bounds determined by lowerBound and upperBound.  The index for dimension i is stored in the array at position i1.

• 

As RTables do not have unique representations, elements of an RTable can be assigned to at any time.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

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

    {

    String mapleArgs[];

    Engine engine;

    ByteRTable a1;

    int index[];

    byte e;

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    a1 = (ByteRTable)engine.evaluate( "Array( 1..2, 1..2, [[1,2],[3,4]], datatype=integer[1]):" );

    index = new int[2];

    e = 11;

    index[0] = 1;

    index[1] = 1;

    a1.assign( index, e );

    e = 12;

    index[0] = 2;

    index[1] = 1;

    a1.assign( index, e );

    e = 13;

    index[0] = 1;

    index[1] = 2;

    a1.assign( index, e );

    e = 14;

    index[0] = 2;

    index[1] = 2;

    a1.assign( index, e );

    System.out.println( a1 );

    }

}

Executing this code produces the following output.

Array(1..2, 1..2, [[11,13],[12,14]], datatype = integer[1], storage =

rectangular, order = Fortran_order)
