Bridge Design Pattern

 Bridge Design Pattern 

Bridge Design Pattern

Simple one line design pattern : when do you need to do combinatorial hierarchy of classes.
handle/body idioms.

Example :
data structure implemented in two way of data.
1. Array form
2. List form

Now you need to create a Stack data strucutre hierarchy for
1. Stack basic interface.
2. StackHanoi only store push new element greater then top.
3. StackFIFO pop stack bottom element.

Now we will look diagram form of this hierarchy before using bridge pattern.

Before Bridge Design Pattern Class Hierarchy.

Now We will look when bridge design pattern used.

After Bridge Design Pattern Class Hierarchy

for code you can look sourcemaking.com . I just shared my understanding. If i got time and found some another example, I may share.
