Class ToTime

java.lang.Object
dev.frostlake.functions.BuiltInFunction
dev.frostlake.functions.scalar.conversion.ToTime
Direct Known Subclasses:
TimeFunction
public class ToTime extends BuiltInFunction
TO_TIME(expr [, format]). With a format the input is read against that model only — a mismatch is "Can't parse '<input>' as time with format '<format>'", the input and the model echoed verbatim — and any date the model reads is dropped; a NULL format is a NULL answer. Without one (or under AUTO) the input is read flexibly.

  • Method Details

    • evaluate

      public Object evaluate(List<Object> args)
      Description copied from class: BuiltInFunction
      Computes the function's result over its already-evaluated argument values. A SQL NULL argument arrives as Java null, and returning null makes the SQL result NULL.
      Specified by:
      evaluate in class BuiltInFunction
      Parameters:
      args - the argument values, in call order
      Returns:
      the function's value for these arguments, or null for SQL NULL

    • getMinArgCount

      public int getMinArgCount()
      Description copied from class: BuiltInFunction
      The fewest arguments a call to this function may pass; fewer is an argument-count error.
      Specified by:
      getMinArgCount in class BuiltInFunction
      Returns:
      the minimum accepted argument count

    • getMaxArgCount

      public int getMaxArgCount()
      Description copied from class: BuiltInFunction
      The most arguments a call to this function may pass; Integer.MAX_VALUE marks a variadic function (see BuiltInFunction.isVariadic()).
      Specified by:
      getMaxArgCount in class BuiltInFunction
      Returns:
      the maximum accepted argument count
