所有已实现的接口:

Closeable, Flushable, AutoCloseable

封闭类:

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.

OutputStream

public 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

OutputStream

public 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

Base64.ENCODE, Base64.DO_BREAK_LINES

方法详细资料

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:

write 在类中 FilterOutputStream

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:

write 在类中 FilterOutputStream

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.

close

public void close()
           throws IOException

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

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 FilterOutputStream

抛出:

IOException

从以下版本开始:
