description Inline Class Overview
The Inline Class refactoring tool within JetBrains Native Refactoring streamlines Java code by simplifying data transfer objects. It identifies classes primarily used to hold data without significant logic and proposes replacing them with direct field usage or a record pattern. This reduces boilerplate code, improves code clarity, and is particularly beneficial for developers working on projects prioritizing clean data structures and efficient value object implementation.
help Inline Class FAQ
What does the Inline Class refactoring do in JetBrains?
Inline Class replaces a small wrapper class with direct use of its fields or values at the places where the class is used. It is meant for data-holder classes whose extra abstraction no longer provides enough value.
When should I use Inline Class instead of keeping a Java class?
It can make sense when a class mainly transfers data and contains little meaningful behavior. You should keep the class when its validation, invariants, methods, or public API are important to the design.
Can Inline Class convert a Java class to a record?
The described tool may suggest direct field usage or a record-style pattern for suitable data classes. The exact result depends on the class structure and the JetBrains IDE and Java version being used.
Does Inline Class change the program's behavior?
The refactoring is intended to preserve behavior while simplifying the data flow. Because it changes many references, the resulting code should still be reviewed and compiled after the transformation.
