方法详细资料

read

public int read()
         throws IOException

Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. If the result is not -1, then the number of bytes read is incremented by 1.

read

public int read(byte[] arg0,
       int off,
       int len)
         throws IOException

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer. If the result is not -1, the the number of bytes read is incremented by the result of the read operation.

抛出:

skip

public long skip(long n)
          throws IOException

Skips over and discards n bytes of data from this input stream. Returns the number of bytes skipped from this stream. If the result is not -1, then the number of bytes is incremented by the total number of bytes skipped.

mark

public void mark(int readlimit)

Marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes. The readlimit arguments tells this input stream to allow that many bytes to be read before the mark position gets invalidated. The number of bytes read from this stream at this instance is noted so that on subsequent calls to reset, the bytesRead can be reset to this value if mark is success.

mark 在类中 FilterInputStream

reset

public void reset()
           throws IOException

Repositions this stream to the position at the time the mark method was last called on this input stream if and only if mark is supported by the input stream. Resets the bytesRead parameter to the mark value.
