LongConverter class

Converts arbitrary values into longs using extended conversion rules:

  • Strings are converted to floats, then to longs
  • DateTime: total number of milliseconds since unix epoсh
  • Boolean: 1 for true and 0 for false

Example

var value1 = LongConverter.toNullableLong('ABC'); // Result: null
var value2 = LongConverter.toNullableLong('123.456'); // Result: 123
var value3 = LongConverter.toNullableLong(true); // Result: 1
var value4 = LongConverter.toNullableLong(new Date()); // Result: current milliseconds
