![]() Global static String getCharAtIndex(String str, Integer index) $/i įor now I will use Paul's method, using Crypto.getRandomInteger() instead of Math. compared to alternatives is their relative small size, of 128-bits, or 16-bytes. ReturnValue += getCharAtIndex(kHexChars, nextByte & 15) The version number is stored in the most significant 4 bits of the 16-bit field. These shortened formats can only be used with Bluetooth. Private static String kHexChars = '0123456789abcdef' include int uuidgen(struct uuid store, int count). For efficiency, the Bluetooth Low Energy (BLE) specification adds support for shortened 16-bit UUIDs.The BluetoothUUID interface provides methods to retrieve these 128-bit UUIDs. The Bluetooth registry contains lists of descriptors, services, and characteristics identified by these UUIDs in addition to a 16- or 32- bit alias, and a name. Sample usage: if (acct.AccountUuid_c = null)Īcct.AccountUuid_c = GuidUtil.NewGuid() A UUID string is a 128-bit UUID, for example 00001818-0000-1000-8000-00805f9b34fb. After working with the code in techtrekker's link (in OP comments) and other resources I cobbled together a standalone, working class for generating GUIDs in Apex code:
