Utility functions to work with buffers (Uint8Array).

Method Summary

Modifier and Type	Method	Description
static Uint8Array	copyUint8Array(Uint8Array uint8Array)	Copy the content of an Uint8Array view to a new ArrayBuffer.
static Uint8Array	createUint8ArrayFromArrayBuffer(byte[] buffer)	Create Uint8Array with initial content from buffer
static Uint8Array	createUint8ArrayFromLen(int len)
static Uint8Array	createUint8ArrayViewFromArrayBuffer(byte[] buffer, int byteOffset, int length)	Create Uint8Array with initial content from buffer
static Object	decodeAny(Uint8Array buf)	Decode an any-encoded value.
static Uint8Array	encodeAny(Object data)	Encode anything as a UInt8Array.
static Uint8Array	fromBase64(String s)
static Uint8Array	fromBase64UrlEncoded(String base64)
static Uint8Array	fromHexString(String hex)	Note: This function expects that the hex doesn't start with 0x.
static String	toBase64(Uint8Array bytes)
static String	toBase64UrlEncoded(Uint8Array buf)	Implements base64url - see https://datatracker.ietf.org/doc/html/rfc4648#section-5
