Base64.InputStream

public Base64.InputStream(java.io.InputStream in,
                  int options)

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

Valid options:

   ENCODE or DECODE: Encode or Decode as data is read.
   DO_BREAK_LINES: break lines at 76 characters
     (only meaningful when encoding)
 

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

参数:

in - the java.io.InputStream from which to read data.

options - Specified options

方法详细资料

read

public int read()
         throws java.io.IOException

Reads enough of the input stream to convert to/from Base64 and returns the next byte.

覆盖:

read 在类中 java.io.FilterInputStream

返回:

next byte

抛出:

java.io.IOException

从以下版本开始:

1.3

read

public int read(byte[] dest,
       int off,
       int len)
         throws java.io.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.

覆盖:

read 在类中 java.io.FilterInputStream

参数:

dest - array to hold values

off - offset for array

len - max number of bytes to read into array

返回:

bytes read into array or -1 if end of stream is encountered.

抛出:

java.io.IOException
