所有已实现的接口：

Closeable, Flushable

包容类：

Base64

public static class Base64.OutputStream
extends FilterOutputStream

A Base64.OutputStream will write data to another java.io.OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.

Constructs a Base64.OutputStream in ENCODE mode.

Base64.OutputStream(OutputStream out, int options)
Constructs a Base64.OutputStream in either ENCODE or DECODE mode.

方法摘要

void	close() Flushes and closes (I think, in the superclass) the stream.
void	flush() Flushes the stream (and the enclosing streams).
void	flushBase64() Method added by PHIL.
void	resumeEncoding() Resumes encoding of the stream.
void	suspendEncoding() Suspends encoding of the stream.
void	write(byte[] theBytes, int off, int len) Calls write(int) repeatedly until len bytes are written.
void	write(int theByte) Writes the byte to the output stream after converting to/from Base64 notation.

构造方法详细信息

Base64.OutputStream

public Base64.OutputStream(OutputStream out)

Constructs a Base64.OutputStream in ENCODE mode.

参数：

out - the java.io.OutputStream to which data will be written.

从以下版本开始：

1.3

Base64.OutputStream

public Base64.OutputStream(OutputStream out,
                           int options)

Constructs a Base64.OutputStream in either ENCODE or DECODE mode.

Valid options:

   ENCODE or DECODE: Encode or Decode as data is read.
   DO_BREAK_LINES: don't break lines at 76 characters
     (only meaningful when encoding)
 

Example: new Base64.OutputStream( out, Base64.ENCODE )

参数：

out - the java.io.OutputStream to which data will be written.

options - Specified options.

从以下版本开始：

1.3

方法详细信息

write

public void write(int theByte)
           throws IOException

Writes the byte to the output stream after converting to/from Base64 notation. When encoding, bytes are buffered three at a time before the output stream actually gets a write() call. When decoding, bytes are buffered four at a time.

覆盖：

类 FilterOutputStream 中的 write

参数：

theByte - the byte to write

抛出：

IOException

从以下版本开始：

1.3

write

public void write(byte[] theBytes,
                  int off,
                  int len)
           throws IOException

Calls write(int) repeatedly until len bytes are written.

覆盖：

类 FilterOutputStream 中的 write

参数：

theBytes - array from which to read bytes

off - offset for array

len - max number of bytes to read into array

抛出：

IOException

从以下版本开始：

1.3

flushBase64

public void flushBase64()
                 throws IOException

Method added by PHIL. [Thanks, PHIL. -Rob] This pads the buffer without closing the stream.

抛出：

IOException - if there's an error.

flush

public void flush()
           throws IOException

Flushes the stream (and the enclosing streams).

指定者：

接口 Flushable 中的 flush

覆盖：

类 FilterOutputStream 中的 flush

抛出：

IOException

从以下版本开始：

2.3

close

public void close()
           throws IOException

Flushes and closes (I think, in the superclass) the stream.

指定者：

接口 Closeable 中的 close

覆盖：

类 FilterOutputStream 中的 close

抛出：

IOException

从以下版本开始：

1.3

suspendEncoding

public void suspendEncoding()
                     throws IOException

Suspends encoding of the stream. May be helpful if you need to embed a piece of base64-encoded data in a stream.

抛出：

IOException - if there's an error flushing

从以下版本开始：

1.5.1

resumeEncoding

public void resumeEncoding()

Resumes encoding of the stream. May be helpful if you need to embed a piece of base64-encoded data in a stream.

从以下版本开始：

1.5.1
