Class Div0

java.lang.Object
dev.frostlake.functions.BuiltInFunction
dev.frostlake.functions.NumericArgumentFunction
dev.frostlake.functions.scalar.math.Div0
public class Div0 extends NumericArgumentFunction
DIV0(a, b) divides like the / operator but returns 0 when the divisor is 0. DIV0NULL(a, b) additionally returns 0 when the divisor is NULL. In both cases a NULL dividend (with a normal, non-zero divisor) yields NULL, matching standard division.

  • 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
