read 在类中 FilterInputStream

返回:

byte value

抛出:

IOException - if socket reading error.

read

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

Returing byte array, from cache of reading socket if needed.

覆盖:

read 在类中 FilterInputStream

参数:

externalBuf - buffer to fill

off - offset

len - length to read

返回:

number of added bytes

抛出:

IOException - if exception during socket reading

              throws IOException

覆盖:

available 在类中 FilterInputStream

抛出:

IOException

reset

public void reset()
           throws IOException

覆盖:

reset 在类中 FilterInputStream

抛出:

IOException
