构造器详细资料

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.
   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.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

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:

1.3

suspendEncoding

public void suspendEncoding()
                     throws IOException

Suspends encoding of the stream. May be helpful if you need to embed a piece of base640-encoded data in a stream.

抛出:

IOException

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 base640-encoded data in a stream.

从以下版本开始:

1.5.1
