Enclosing class:
Base64

public static class Base64.InputStream extends FilterInputStream

      public InputStream(InputStream in)
      Constructs a
      invalid @link
      Base64#InputStream
      in DECODE mode.
      Parameters:
      in - the InputStream from which to read data.

    • InputStream

      public InputStream(InputStream in, int options)
      Constructs a
      invalid @link
      Base64#InputStream
      in either ENCODE or DECODE mode.

      Valid options:

         ENCODE or DECODE: Encode or Decode as data is read.
         DONT_BREAK_LINES: don't break lines at 76 characters
           (only meaningful when encoding)
           Note: Technically, this makes your encoding non-compliant.
       

      Example: new Base64.InputStream( in, Base64.DECODE )

      Parameters:
      in - the InputStream from which to read data.

      read in class FilterInputStream
      Returns:
      next byte
      Throws:
      IOException

    • read

      public int read(byte[] dest, int off, int len) throws IOException
      Calls read() repeatedly until the end of stream is reached or len bytes are read. Returns number of bytes read into array or -1 if end of stream is encountered.
      Overrides:
      read in class FilterInputStream
      Parameters:
      dest - array to hold values
      off - offset for array
      len - max number of bytes to read into array
      Returns:
      bytes read into array or -1 if end of stream is encountered.
      Throws:
      IOException
