description Push Down Members Overview
Push Down Members is a refactoring operation available in JetBrains development environments for supported object-oriented languages. It moves selected methods, fields, or other class members from a superclass into one or more subclasses where they are actually needed. Developers use it to narrow a base class's responsibilities while preserving relevant behavior in derived classes.
help Push Down Members FAQ
What does Push Down Members do in JetBrains IDEs?
Push Down Members moves selected methods, fields, or other class members from a superclass into one or more subclasses. It is useful when a member is no longer needed by the parent class.
When should a developer use Push Down Members?
Use it when a method or field only belongs to specific child classes rather than the whole inheritance hierarchy. Moving it can make the superclass smaller and better reflect the actual design.
Does Push Down Members work on every programming language in JetBrains?
No. Availability depends on the JetBrains development environment and the supported object-oriented language. The available members and preview options can also vary by language plugin and project structure.
Can Push Down Members move both methods and fields?
Yes. The operation can apply to selected methods, fields, and other supported class members. The IDE updates the relevant subclass declarations while checking for conflicts that could change behavior.
