public class Base64OutputStream
extends java.io.FilterOutputStream

An output stream filter that takes arbitrary bytes and outputs their base64 encoding. Call flush() or close() to write out the final padding. The class also automatically puts line breaks in the output stream.

Field Summary

Fields inherited from class java.io.FilterOutputStream
`out`

Constructor Summary
`Base64OutputStream(java.io.PrintStream out)` Create a stream that does not insert line breaks.
`Base64OutputStream(java.io.PrintStream out, int quadsPerLine)`

Method Summary
`void` | `close()` This flushes the stream and closes the next stream downstream.
`void` | `flush()` Calling this will put the ending padding on the base64 stream, so don't call it until you have no data left.
`void` | `write(byte[] buffer)`
`void` | `write(byte[] buffer, int offset, int count)`
`void` | `write(int oneByte)`

Constructor Detail

### Base64OutputStream

    public Base64OutputStream(java.io.PrintStream out)

  Create a stream that does not insert line breaks. To have line breaks, use the other constructor.

### Base64OutputStream

    public Base64OutputStream(java.io.PrintStream out,
                              int quadsPerLine)

Parameters:
  `quadsPerLine` - Number of 4-character blocks to write before outputting a line break. For example, for 76-characters per line, pass in 76/4 = 19.

Method Detail

### write

    public void write(int oneByte)
               throws java.io.IOException

  Overrides:
    `write` in class `java.io.FilterOutputStream`
    `java.io.IOException`

### close

    public void close()
               throws java.io.IOException

  This flushes the stream and closes the next stream downstream.

  Overrides:
    `close` in class `java.io.FilterOutputStream`
    `java.io.IOException`

### flush

    public void flush()
               throws java.io.IOException

  Calling this will put the ending padding on the base64 stream, so don't call it until you have no data left. The class does no unnecessary buffering, so you probably shouldn't call it at all.

  Overrides:
    `flush` in class `java.io.FilterOutputStream`
    `java.io.IOException`

### write

    public void write(byte[] buffer)
               throws java.io.IOException

  Overrides:
    `write` in class `java.io.FilterOutputStream`
    `java.io.IOException`

### write

    public void write(byte[] buffer,
                      int offset,
                      int count)
               throws java.io.IOException

  Overrides:
    `write` in class `java.io.FilterOutputStream`
    `java.io.IOException`
