Method Detail

readObject

public Object readObject()
                  throws ClassNotFoundException,
                         IOException

Enabled: Read and return an object. The class that implements this interface defines where the object is "read" from.

Returns:

the object read from the stream

ClassNotFoundException

IOException

read

public int read()
         throws IOException

Enabled: Reads a byte of data. This method will block if no input is available.

Returns:

the byte read, or -1 if the end of the stream is reached.

IOException

read

public int read(byte[] b)
         throws IOException

Enabled: 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.

IOException

read

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

Enabled: 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.

IOException

skip

public long skip(long n)
          throws IOException

Enabled: Skips n bytes of input.

Parameters:

n - the number of bytes to be skipped

Returns:

the actual number of bytes skipped.

IOException

available

public int available()
              throws IOException

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

Returns:

the number of available bytes.

IOException

close

public void close()
           throws IOException

Enabled: Closes the input stream. Must be called to release any resources associated with the stream.
