		const jau::nsize_t	haystack_length,
		const uint8_t	needle_b[],
		const jau::nsize_t	needle_length,
		const lb_endian_t	byte_order )

staticnoexcept

Find index of needle within haystack in the given byte order.

The returned index will be adjusted for the desired byte order.

lb_endian::big will return index 0 for the leading byte like the toString() representation from left (MSB) to right (LSB).
lb_endian::little will return index 5 for the leading byte

Parameters

haystack_b	haystack data
haystack_length	haystack length
needle_b	needle data
needle_length	needle length
byte_order	byte order will adjust the returned index, lb_endian::big is equivalent with toString() representation from left (MSB) to right (LSB).

Returns: index of first element of needle within haystack or -1 if not found. If the needle length is zero, 0 (found) is returned.

inlinenoexcept

Finds the index of given EUI48Sub needle within this instance haystack in the given byte order.

The returned index will be adjusted for the desired byte order.

lb_endian::big will return index 0 for the leading byte like the toString() representation from left (MSB) to right (LSB).
lb_endian::little will return index 5 for the leading byte

Parameters

needle
byte_order	byte order will adjust the returned index, lb_endian::big is equivalent with toString() representation from left (MSB) to right (LSB).

Returns: index of first element of needle within this instance haystack or -1 if not found. If the needle length is zero, 0 (found) is returned.

◆ toString()

std::string EUI48Sub::toString ( ) const

noexcept

Returns the EUI48 sub-string representation with MSB first (lb_endian::big), less or equal 17 characters representing less or equal 6 bytes as upper case hexadecimal numbers separated via colon, e.g.

01:02:03:0A:0B:0C, 01:02:03:0A, :, (empty).
