All Implemented Interfaces:

VarFunction

Enclosing class:

StringFunctions

public static class StringFunctions.Format
extends TypedFunction

#{format(pattern, args...)} — Java formatter-style formatting. Pattern uses Java Formatter syntax (e.g. %s, %d, %.2f). Variadic args; coerced per Java Formatter rules at invocation.

Example:

#{format("%s-%03d", ${prefix}, ${counter})}

All args are passed as raw String values; format specifiers like %d will convert numeric strings via Integer.parseInt(java.lang.String, int) / Long.parseLong(java.lang.String, int) as needed. %s accepts any string verbatim.
