// Example using pointers to member functions var member_pointer = require("member_pointer"); function check(what, expected, actual) { if (expected != actual) { throw new Error( "Failed: ", what, " Expected: ", expected, " Actual: ", actual); } } // Get the pointers area_pt = member_pointer.areapt(); perim_pt = member_pointer.perimeterpt(); // Create some objects s = new member_pointer.Square(10); // Do some calculations check("Square area ", 100.0, member_pointer.do_op(s, area_pt)); check("Square perim", 40.0, member_pointer.do_op(s, perim_pt)); memberPtr = member_pointer.areavar; memberPtr = member_pointer.perimetervar; // Try the variables check("Square area ", 100.0, member_pointer.do_op(s, member_pointer.areavar)); check("Square perim", 40.0, member_pointer.do_op(s, member_pointer.perimetervar)); // Modify one of the variables member_pointer.areavar = perim_pt; check("Square perimeter", 40.0, member_pointer.do_op(s, member_pointer.areavar)); // Try the constants memberPtr = member_pointer.AREAPT; memberPtr = member_pointer.PERIMPT; memberPtr = member_pointer.NULLPT; check("Square area ", 100.0, member_pointer.do_op(s, member_pointer.AREAPT)); check("Square perim", 40.0, member_pointer.do_op(s, member_pointer.PERIMPT)); // Typedefs check("Square perim", 40.0, member_pointer.do_op_td(s, perim_pt)); check("Add by value", 3, member_pointer.call1(member_pointer.ADD_BY_VALUE, 1, 2)); check("Add by pointer", 7, member_pointer.call2(member_pointer.ADD_BY_POINTER, 3, 4)); check("Add by reference", 11, member_pointer.call3(member_pointer.ADD_BY_REFERENCE, 5, 6));
