Code Smell 08 - Long Chains Of Collaborations

Making long chains generate coupling and ripple effect.
Any chain change breaks the code.

Problems

• Coupling

• Break encapsulation

Solutions

• Create intermediate methods.
• Think about Law of Demeter.
• Create higher level messages.

Sample Code

Wrong

Right

Detection

Automatic detection is possible using parsing trees.

Also Known as

• Law of Demeter

Tags

• Declarative

• Encapsulation

Conclusion

Avoid successive message calls. Try to hide the intermediate collaborations and create new protocols.
