read

public int read()
         throws IOException

Description copied from class: MarshallerObjectInputStream

Reads the next byte of data from the input stream. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Specified by:

read in interface ByteInput

Specified by:

read in interface ObjectInput

Overrides:

read in class MarshallerObjectInputStream

Returns:

the next byte, or -1 if the end of stream has been reached

Throws:

IOException - if an error occurs

read

public int read(byte[] buf)
         throws IOException

Description copied from class: MarshallerObjectInputStream

Read some bytes from the input stream into the given array. Returns the number of bytes actually read (possibly zero), or -1 if the end of stream has been reached.

Specified by:

read in interface ByteInput

Specified by:

read in interface ObjectInput

Overrides:

read in class MarshallerObjectInputStream

Parameters:

buf - the destination array

Returns:

the number of bytes read (possibly zero), or -1 if the end of stream has been reached

Throws:

IOException - if an error occurs

read

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

Description copied from class: MarshallerObjectInputStream

Read some bytes from the input stream into the given array. Returns the number of bytes actually read (possibly zero), or -1 if the end of stream has been reached.

Specified by:
