Base64OutputStream

public Base64OutputStream(int size,
                          Writer writer)

Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

参数:

size - the initial size.

writer - the writer we'll flush to once we reach our capacity

抛出:

IllegalArgumentException - if size is negative.

方法详细资料

write

public void write(int b)
           throws IOException

Writes the specified byte to this byte array output stream.

指定者:

write 在类中 OutputStream

参数:

b - the byte to be written.

抛出:

IOException

write

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

Writes len bytes from the specified byte array starting at offset off to this byte array output stream.

覆盖:

write 在类中 OutputStream

参数:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

抛出:

IOException

write

public void write(byte[] b)
           throws IOException

Calls through to write(byte[], int, int)/

覆盖:

write 在类中 OutputStream

参数:

b - the bytes to write

抛出:

IOException - if an error occurs

close

public void close()
           throws IOException

Closing Base64OutputStreamWriter does nothing.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 OutputStream

抛出:

IOException

finish

public void finish()
            throws IOException

Encodes the remaining bytes and flushes the char[] to the wrapped Writer.

抛出:

IOException - if an error occurs writing the remaining bytes

getTotalCharsWritten

public int getTotalCharsWritten()

返回:

the total number of characters written
