dev.frostlake.functions.scalar.conversion.ToBinary

public class ToBinary
extends BuiltInFunction

TO_BINARY(string [, format]) — decodes the input string into a BinaryValue using format (default HEX). HEX: the input is hexadecimal digits; BASE64: base64-decoded; UTF-8: the input's UTF-8 bytes. A binary input passes through unchanged. NULL → NULL.

Modifier and Type	Method	Description
Object	evaluate(List<Object> args)	Computes the function's result over its already-evaluated argument values.
int	getMaxArgCount()	The most arguments a call to this function may pass; Integer.MAX_VALUE marks a variadic function (see BuiltInFunction.isVariadic()).
int	getMinArgCount()	The fewest arguments a call to this function may pass; fewer is an argument-count error.

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
