In computer science
, the interface pattern
isn't a specific pattern
amongst design patternss
. It's a general method
for structuring programs
so that they're simpler to understand. In general, an interface
is a class
which provides the programmer
with a simpler or more program-specific way of accessing other classes.
An interface could contain a set of objects and provide simpler, higher-level functions to programmer (for example, the facade pattern), it could provide a cleaner or more specific way of using complicated classes (a "wrapper" class), it could be used to act as "glue" between two different API's (the adapter pattern), and more!
Other kinds of interface patterns are: delegation pattern, composite pattern, and bridge pattern.
