Basics
Cast int array to this type.
int[ ] arr = new int[ ] { 3, 5, 7 };
Index3 idx3_from_arr = (Index3)arr;
// idx3_from_arr value is (3, 5, 7);
Cast this type to int array.
Index3 idx3 = new Index3(3, 5, 7);
int[ ] arr = (int) idx3;
// arr value is [3, 5, 7];
Index types support the following methods:
Clone – This method makes an exact copy, equivalent to using the copy constructor.
Index3 idx = new Index3(3, 5, 7);
Index3 idx2 = idx.clone();
// idx2 value is (3, 5, 7). Equivalent to copy ctor
Dot – This method multiplies Index properties (I * I, J * J, ...) and sums the results.
Index3 idx_1 = new Index3(3, 5, 7);
Index3 idx_2 = new Index3(9, 13, 17);
int dot = Index3.Dot(idx_1, idx_2)
// dot = 3*9 + 5*13 + 7*17 = 211
Equals – This method completes an equality check.
Index3 idx_1 = new Index3(3, 5, 7);
Index3 idx_2 = new Index3(9, 13, 17);
if (idx_1.Equals(idx_2))
// result is false
GetHashCode – This method returns a hash code for the Index instance.
Index3 idx3 = new Index3(3, 5, 7);
int hc = idx3.GetHashCode();
