Returns true if and only if this Filer object is at the end of an object's data.

This will be true when the filter is at any of the following: 

• A subclass data marker.
• The start of an object's xdata.
• The start of embedded object's data.
• The start of another object's data.
• The end of a file.

The default implementation of this function does nothing but throw an exception.
