public class StringToDate
extends org.nfunk.jep.function.PostfixMathCommand

A function that converts a string into a date. The parse pattern may be specified or not. A different behavior may be expected, depending on the number of parameters. E.g.:

• str2date("2015-10-03T08:00:01.123Z")
  • attempts to parse the string by trying a set of different parse patterns, supporting RFC-3339, RFC-822 and a set of common ISO-8601 variations (fastest choice when handling RFC-3339 dates). Also recommended for other formats when the parse pattern is unknown or heterogeneous, but it comes with a cost)
• str2date("2015-10-03", "yyyy-MM-dd")
  • attempts to parse the given string using the specified parse pattern in the second parameter (fastest approach when possible, but does not support RFC-3339)
• str2date("2015-10-03", "yyyy-MM-dd'T'HH", "yyyy-MM-dd'T'HH", ...)
  • attempts to parse the given string by evaluating the parse patterns provided in the second and following parameters, until a pattern that fits the date is evaluated
