operator == method

@override bool operator ==(Object b)

compare two arrays

Examples

var n = Array([1, 2, 3]);
var n2 = Array([1, 2, 3]);

print(n == n2);

/* output:
true
*/

Implementation

@override
bool operator ==(b) {
  if (b is Array2d) {
    _checkArray2dColumnsLength(this);
    _checkArray2dColumnsLength(b);
    _checkArray2dLength(this, b);

    for (var i = 0; i < length; i++) {
      if (this[i] != b[i]) {
        return false;
      }
    }
    return true;
  } else {
    throw ('the right object has to be an Array2d type');
  }
}
