In object oriented programming , a filter object is an objectcomputerscienceobject which receives a stream of data as its input and produces the stream of data as its output based on the data from input stream. So a filter object filters an input data transforming it into output data. Often the input and output streams are streams of characters, but these also may be streams of arbitrary objects.

In object oriented programming , a God object is an Objectcomputerscienceobject that knows too much or does too much . The God object is an example of an anti pattern . The basic idea behind structured programming is that a big problem is broken down into several smaller problems a divide and conquer algorithm divide and conquer strategy and solutions are created for each of them. Once the small problems have been solved, the big problem as a whole has been solved. Therefore there is only one object about which an object needs to know everything itself . Likewise, there is only one set of problems an object needs to solve its own . God object based code does not follow this approach. Instead, most of a program s overall functionality is coded into a single all knowing object, which maintains most of the information about the entire program and provides most of the subroutine methods for manipulating this data. Because this object holds so much data and requires so many methods, its role in the program becomes God like all encompassing . Instead of program objects communicating amongst themselves directly, the other objects within the program rely on the God object for most of their information and interaction. Since the God object is referenced by so much of the other code, maintenance becomes more difficult than it would in a more evenly divided programming design. A God object is the object oriented analogue of failing to use subroutine s in Procedural programming procedural ... creating a God object is typically considered bad programming practice, this technique is occasionally ... book last Riel first Arthur J. title Object Oriented Design Heuristics year 1996 publisher Addison Wesley location Boston, MA isbn 020163385X chapter Chapter 3 Topologies of Action Oriented Vs.
