Method Detail

• readObject

  Object readObject()           throwsClassNotFoundException,IOException

  IOException - If an I/O error has occurred.

• read

  int read​(byte[] b)  throwsIOException

  Reads into an array of bytes. This method will block until some input is available.

  Parameters:

  b - the buffer into which the data is read

  Returns:

  the actual number of bytes read, -1 is returned when the end of the stream is reached.

  Throws:

  IOException - If an I/O error has occurred.

• read

  int read​(byte[] b,         int off,         int len)  throwsIOException

  Reads into an array of bytes. This method will block until some input is available.

  Parameters:

  b - the buffer into which the data is read

  off - the start offset of the data

  len - the maximum number of bytes read

  Returns:

  the actual number of bytes read, -1 is returned when the end of the stream is reached.

  Throws:

  IOException - If an I/O error has occurred.

• skip

  long skip​(long n)   throwsIOException

  Skips n bytes of input.

  Parameters:

  n - the number of bytes to be skipped

  Returns:

  the actual number of bytes skipped.

  Throws:

  IOException - If an I/O error has occurred.

• available

  int available()       throwsIOException

  Returns the number of bytes that can be read without blocking.
