4 Using MWArra y Classes

index

Index of the requested element in the MWStructArray

In the case where index is of type int, the valid range for index is 1<=index

<= N

,whereN is the total number of elements in the array.

Inthecasewhere

index is of type int[],eachelementoftheindex vector

is an index along one dimension of the

MWStructArray object. T he valid

range for any index is

1 <= index[i] <= N[i],whereN[i] is the size of the

ith dimension.

Exceptions

The get method throws the following exception:

IndexOutOfBoundsException

The specified index parameter is invalid.

Example — Getting Struct ure Array Data with get

Get the data stored in field f2 at index (1,1) of MWStructArray object S:

int[] sdims = {1, 2};

String[] sfields = {"f1", "f2", "f3"};

Integer val = new Integer(555);

MWStructArray S = new MWStructArray(sdims, sfields);

int[] index = {1, 1};

S.set(sfields[2], index, val);

Object d_out = S.get(sfields[2], index);

System.out.println("Structure data S(1,1).f2 is " +

d_out.toString());

When run, the example displays this output:

4-126

1 2 ... 197 198 199 200 201 202 203 204 205 206 207 ... 291 292
