Parameter

Parameter

Description

hexString

The hexadecimal string representing a byte array. The lexical value space defined in XML Schema Part 2: Datatypes for xsd:hexBinary is expected: "hexBinary has a lexical representation where each binary octet is encoded as a character tuple, consisting of two hexadecimal digits ([0-9a-fA-F]) representing the octet code. For example, '0FB7' is a hex encoding for the 16-bit integer 4023 (whose binary representation is 111110110111)."

Return

A byte array representing the hexadecimal string

Declaration

public static byte[] toByteArrayFromHexString(String s)
