Method Write

pkg/util/base64/base64.go:38–70

Write encodes p in an internal buffer.

(p []byte)

// Write encodes p in an internal buffer.
func (e *Encoder) Write(p []byte) {
	// Leading fringe.
	if e.nbuf > 0 {
		var i int
		for i = 0; i < len(p) && e.nbuf < 3; i++ {
			e.buf[e.nbuf] = p[i]
			e.nbuf++
		}
		p = p[i:]
		if e.nbuf < 3 {
			return
		}
		e.enc.Encode(e.out[:], e.buf[:])
		_, _ = e.sb.Write(e.out[:4])
		e.nbuf = 0
	}

	// Large interior chunks.
	for len(p) >= 3 {
		nn := len(e.out) / 4 * 3
		if nn > len(p) {
			nn = len(p)
			nn -= nn % 3
		}
		e.enc.Encode(e.out[:], p[:nn])

}

// String flushes any pending output from the encoder and returns the encoded
// string. The Encoder is reset to its initial state so it can be reused.
