Set or obtain data attributes

The length() method returns the total length of the entire data stream. The getAutoAlignment() method retrieves the TRUE or FALSE (on or off) state of the auto alignment feature. The setAutoAlignment() method sets the state to TRUE or FALSE: 
public int length();
public boolean getAutoAlignment();
public void setAutoAlignment(boolean value);
Important: Setting the auto alignment feature might result in discarded bytes from the input stream if the data is not already aligned. JDBC applications should provide aligned data or set the auto alignment feature to FALSE.
