Method Detail- 
writeObjectvoid writeObject(Object obj) throws IOException Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.- Parameters:
- obj- the object to be written
- Throws:
- IOException- Any of the usual Input/Output related exceptions.
 
 - 
writevoid write(int b) throws IOExceptionWrites a byte. This method will block until the byte is actually written.- Specified by:
- writein interface- DataOutput
- Parameters:
- b- the byte
- Throws:
- IOException- If an I/O error has occurred.
 
 - 
writevoid write(byte[] b) throws IOExceptionWrites an array of bytes. This method will block until the bytes are actually written.- Specified by:
- writein interface- DataOutput
- Parameters:
- b- the data to be written
- Throws:
- IOException- If an I/O error has occurred.
 
 - 
writevoid write(byte[] b, int off, int len) throws IOExceptionWrites a sub array of bytes.- Specified by:
- writein interface- DataOutput
- Parameters:
- b- the data to be written
- off- the start offset in the data
- len- the number of bytes that are written
- Throws:
- IOException- If an I/O error has occurred.
 
 - 
flushvoid flush() throws IOExceptionFlushes the stream. This will write any buffered output bytes.- Throws:
- IOException- If an I/O error has occurred.
 
 - 
closevoid close() throws IOExceptionCloses the stream. This method must be called to release any resources associated with the stream.- Specified by:
- closein interface- AutoCloseable
- Throws:
- IOException- If an I/O error has occurred.
