format

fun format(value: String): String(source)

Formats a TAN to canonical form: 10-character uppercase, no separators.

Applies the same normalisation as validate before formatting. TAN has no published display separator convention — output is the raw uppercase string: e.g. "MUMD12345A".

This method is idempotent: format(format(x)) == format(x).

Return

Canonical 10-character uppercase TAN string.

Parameters

value

Raw TAN string.

Throws

IllegalArgumentException

if value is not a valid TAN. The exception message includes the (truncated) input for diagnostics.

Samples

check(TAN.format("pdes03028f") == "PDES03028F")
