方法详细信息

getBytesRead

public long getBytesRead()

Returns the number of bytes, which have been read by the stream.

返回：

Number of bytes, which have been read so far.

available

public int available()
              throws java.io.IOException

Returns the number of bytes, which are currently available, without blocking.

覆盖：

类 java.io.InputStream 中的 available

返回：

Number of bytes in the buffer.

抛出：

java.io.IOException - An I/O error occurs.

read

public int read()
         throws java.io.IOException

Returns the next byte in the stream.

指定者：

类 java.io.InputStream 中的 read

返回：

The next byte in the stream, as a non-negative integer, or -1 for EOF.

抛出：

java.io.IOException - An I/O error occurred.

read

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

Reads bytes into the given buffer.

覆盖：

类 java.io.InputStream 中的 read

参数：

b - The destination buffer, where to write to.

off - Offset of the first byte in the buffer.

len - Maximum number of bytes to read.

返回：

Number of bytes, which have been actually read, or -1 for EOF.

抛出：

java.io.IOException - An I/O error occurred.

close

public void close()
           throws java.io.IOException

Closes the input stream.

指定者：

接口 java.io.Closeable 中的 close

覆盖：

类 java.io.InputStream 中的 close

抛出：

java.io.IOException - An I/O error occurred.

skip

public long skip(long bytes)
          throws java.io.IOException

Skips the given number of bytes.

覆盖：

类 java.io.InputStream 中的 skip

参数：

bytes - Number of bytes to skip.

返回：

The number of bytes, which have actually been skipped.

抛出：

java.io.IOException - An I/O error occurred.

isClosed

public boolean isClosed()

Returns, whether the stream is closed.

返回：

True, if the stream is closed, otherwise false.
