Input Stream Meets the Decorator Pattern
Figure
7-5
depicts the class diagram that includes some commonly used input stream classes. You can refer to the
API documentation of the
java.io
package for the complete list of the input stream classes. The comments in the
class diagram compare input stream classes with the classes in the decorator pattern. Notice that the class diagram
for the input streams is similar to the class diagram for your drink application, which was also based on the decorator
pattern. Table
7-1
compares the classes in the decorator pattern, the drink application, and the input streams.
