Maxims

Refactoring and Smells

Composing Methods: Extract Method | Inline Method | Inline Temp | Replace Temp with Query | Introduce Explaining Variable | Split Temporary Variable | Remove assignments to Parameters | Replace Method with Method Object | Substitute Algorithm
Moving Features Between Objects: Move Method | Move Field | Extract Class | Inline Class | Hide Delegate | Remove Middle Man | Introduce Foreign Method | Introduce Local Extension
Organising Data: Self Encapsulate Field | Replace Data Value with Object | Change Value to Reference | Change Reference to Value | Replace Array with Object | Duplicate Observed Data | Change Unidirectional Association to Bidirectional | Change Bidirectional Association to Unidirectional | Replace Magic Number with Symbolic Constant | Encapsulate Field | Encapsulate Collection | Replace Type Code with Class | Replace Type Code with Subclass | Replace Type Code with State/Strategy
Simplifying Conditional Expressions: Decompose Conditional | Consolidate Conditional Expression | Consolidate Duplicate Conditional Fragments | Remove Control Flag | Replace Nested Conditional with Guard Clauses | Replace Conditional with Polymorphism | Introduce Null Object | Introduce Assertion
Making Method Calls Simpler: Rename Method | Add Parameter | Remove Parameter | Separate Query from Modifier | Parameterise Method | Replace Parameter with Explicit Methods | Preserve Whole Object | Replace Parameter with Method | Introduce Parameter Object | Replace Parameter Object | Remove Setting Method | Hide Method | Replace Constructor with Factory Method | Encapsulate Downcast | Replace Error Code with Exception | Replace Exception with test
Dealing with Generalisation: Pull Up Field | Pull Up Method | Pull Up Constructor Body | Push Down Field | Push Down Method | Extract Subclass | Extract Superclass | Extract Interface | Collapse Hierarchy | Form Template Method | Replace Inheritance with Delegation
Big Refactorings: Tease Apart Inheritance | Convert Procedural Design to Objects | Separate Domain from Presentation | Extract Hierarchy

Class Level: Alternative classes with different interfaces smell | Data class smell | Data clumps smell | Divergent change smell | Duplicate code smell | Inappropriate intimacy smell | Incomplete library class smell | Large class smell | Lazy class smell | Message chain smell | Middle man smell | Parallel inheritance hierarchies smell | Primitive obsession smell | Refused bequest smell | Shotgun surgery smell | Speculative generality smell | Temporary field smell

Method Level: Comments smell | Feature envy smell | Long method smell | Long parameter list smell | Switch statement smell
