refactor: Drop empty overriden methods in FairDetector classes #1594
Conversation
Most classes that derive from FairDetector override a bunch of member functions with an empty function. But the original one is already empty. So there is no need to override them. Just remove all of this. If someone wants to customize / use those hooks, they can override the hook that they need.
📝 WalkthroughWalkthroughThis pull request includes updates across multiple header files, primarily focusing on copyright year changes from 2022 to 2024 and the removal of several virtual method declarations that were either unused or commented out. The methods removed include Changes

20-83: Consider adding documentation about available detector hooksSince we're cleaning up empty overrides, it would be helpful to add documentation (possibly in the class comment) listing all available detector hooks that derived classes can override. This would make it easier for future developers to understand which methods they can implement for custom behavior.

1-89: LGTM: Clean removal of empty overridesThe removal of empty virtual method overrides improves code maintainability by:
- Reducing redundant code
- Simplifying the class interface
- Maintaining the ability to override these methods when needed (they're still available from the base class)
The remaining virtual methods (
ProcessHits,Register,Reset, etc.) are essential for detector functionality and correctly preserved.For future detector implementations:
- Override these removed methods only when specific detector behavior is needed
- The base class implementations will be used by default
templates/project_stl_containers/NewDetector/NewDetector.h (1)
The search results show that the virtual methods are still present in the base class
FairDetector.hwith empty implementations:virtual void FinishPrimary() {} virtual void FinishRun() {} virtual void BeginPrimary() {} virtual void PostTrack() {} virtual void PreTrack() {} virtual void BeginEvent() {}Removing these methods from derived class
NewDetectorwould break the inheritance contract.The virtual methods should be kept in the derived class to maintain proper inheritance and allow for future implementations. Empty implementations are acceptable, but complete removal breaks the interface contract.

- Which methods must be overridden by derived classes
- Which methods are optional to override
- When empty overrides should be avoided
This would help future developers make informed decisions about method overrides.
Consider adding this documentation:
/** * FairTutPropDet - Tutorial Propagator Detector * * Required overrides: * - ProcessHits: Called for each step during simulation * - ConstructGeometry: Creates the detector geometry * * Optional overrides: * - Only override other virtual methods when custom behavior is needed * - Avoid empty overrides as they are redundant with base class implementations */

2-2: LGTM: Copyright year update
The copyright year range has been appropriately updated to include 2024.
Line range hint 20-83: Verify the removal of empty overrides and remaining virtual methods
The class correctly maintains essential overrides like ProcessHits, Register, GetCollection, Reset, ConstructGeometry, EndOfEvent, IsSensitive, and CloneModule. Let's verify that the removed methods were indeed empty in both base and derived classes.
The remaining overrides appear necessary as they provide core detector functionality:
ProcessHits: Handles simulation stepsRegister,GetCollection: Manage data collectionsReset,EndOfEvent: Handle event lifecycleConstructGeometry: Creates detector geometryIsSensitive: Determines sensitive volumesCloneModule: Supports module cloning
✅ Verification successful
Removal of empty virtual methods is safe and correct
The verification shows that:
- In FairDetector.h, all removed methods (CopyClones, FinishPrimary, FinishRun, BeginPrimary, PostTrack, PreTrack, BeginEvent) were empty virtual methods with
{}implementations - The Pixel class had no custom implementations of these methods (no matches in Pixel.cxx)
- While FairMCApplication does call these methods on detectors, the empty implementations in the base class (FairDetector) ensure that removing these empty overrides from Pixel class doesn't change any behavior

Line range hint 1-89: Verify base class methods in FairDetector
The removal of empty virtual method overrides aligns with the PR objectives. Let's verify these methods exist in the base class.
✅ Verification successful
Empty virtual method overrides were correctly removed - base class provides default implementations
The verification confirms that all removed virtual methods (SetSpecialPhysicsCuts, FinishPrimary, FinishRun, BeginPrimary, PostTrack, PreTrack, BeginEvent) are declared in the base classes with empty default implementations:
SetSpecialPhysicsCutsinFairModule.h- All other methods in
FairDetector.h
Since these methods already have default implementations in the base classes, removing the empty overrides in NewDetector is the correct approach and aligns with good coding practices by reducing redundant code.

Let's verify that this template correctly reflects the intended changes to remove empty overridden methods and stays in sync with the base class.
✅ Verification successful
Let me generate additional verification scripts to check the alignment between the template and base class more thoroughly.
Let me try one more verification with modified patterns to better detect the methods:
Template correctly reflects base class requirements and recent changes
The verification shows that the NewDetector template is properly aligned with FairDetector base class:
- It implements all required pure virtual methods (ProcessHits, Register, GetCollection, Reset)
- It correctly omits the deprecated empty virtual methods (SetSpecialPhysicsCuts, FinishPrimary, FinishRun, BeginPrimary, PostTrack, PreTrack, BeginEvent) that are now provided with default implementations in FairDetector
- It maintains only the necessary virtual methods that are commonly overridden (Initialize, EndOfEvent, CloneModule, IsSensitive)
The template is up-to-date and provides a clean starting point for new detector implementations.

The class maintains a clean and well-organized structure with:
- Essential virtual method overrides for detector functionality
- Clear separation between public interface and private implementation
- Proper memory management
- Good documentation
The removal of empty overrides helps reduce maintenance burden while preserving the ability to override methods when needed in concrete implementations.
Line range hint 1-90: Verify completeness of empty method removal
The removal of empty overridden methods aligns with the PR objectives. However, let's verify if we've caught all potential candidates for removal.
✅ Verification successful
No empty virtual methods found that require removal
Based on the verification results:
- All virtual methods declared in
NewDetector.hhave corresponding implementations inNewDetector.cxx - Only one inline implementation exists in the header (
Reset()), but it contains actual functionality:fNewDetectorPointCollection->Clear() - Another inline implementation (
CloneModule()) also contains actual functionality:return new NewDetector(*this)
The codebase appears to be clean with respect to empty method implementations, and no further removals are necessary.

Line range hint 1-93: Verify framework compatibility after method removals
The removal of empty overridden methods aligns with the PR objectives. However, let's verify that these removed methods (CopyClones, FinishPrimary, FinishRun, BeginPrimary, PostTrack, PreTrack, BeginEvent) are indeed optional in the framework.
Consider documenting in the base class (FairDetector) that these hooks are optional and can be overridden when specific behavior is needed. This will help future developers understand when to implement these methods.
✅ Verification successful
Empty method overrides can be safely removed
The verification results show that these methods are optional in the framework:
- All removed methods (
CopyClones,FinishPrimary,FinishRun,BeginPrimary,PostTrack,PreTrack,BeginEvent) are defined as empty virtual methods inFairDetectorbase class with empty default implementations{} - The methods are called by
FairMCApplicationduring simulation lifecycle, but since they have default implementations, derived classes are not required to override them - Other detector implementations like
FairGeaneApplicationalso use empty implementations, confirming these are optional hooks
The removal of these empty overrides aligns with the PR objectives and does not impact framework functionality since the base class provides suitable default behavior.

While the removal of several empty overrides is a good improvement, let's verify if we've caught all cases and maintain consistency across the codebase.
✅ Verification successful
Based on the gathered information, I can now provide a final response:

The review of FairTutPropDet shows that:
- All pure virtual methods from FairDetector base class are implemented:
- ProcessHits()
- Register()
- GetCollection()
- Reset()
- The virtual method Initialize() is not overridden because it's optional (not pure virtual)

The following virtual methods have been removed as they were empty overrides: CopyClones, FinishPrimary, FinishRun, BeginPrimary, PostTrack, PreTrack, and BeginEvent. Let's verify that no derived classes depend on these methods.
✅ Verification successful
Removed empty virtual methods are safe to remove
The removed virtual methods (CopyClones, FinishPrimary, FinishRun, BeginPrimary, PostTrack, PreTrack, and BeginEvent) were empty overrides from the base class FairDetector. The search results confirm:
- These methods are defined as empty virtual methods in FairDetector.h:
virtual void CopyClones(...) {}
virtual void FinishPrimary() {}
virtual void FinishRun() {}
virtual void BeginPrimary() {}
virtual void PostTrack() {}
virtual void PreTrack() {}
virtual void BeginEvent() {}-
No derived classes inherit from FairTutorialDet1, so removing these empty overrides won't affect any child classes.
-
The base class FairMCApplication does call these methods on detectors, but since the base class FairDetector provides empty implementations, removing the empty overrides in FairTutorialDet1 will simply fall back to these same empty implementations.

2-2: LGTM: Copyright year update
Standard maintenance update of the copyright year to 2024.
Line range hint 1-153: Verify removal of empty virtual method overrides
The removal of empty virtual method overrides aligns with the PR objectives. However, let's verify that:
- These methods are indeed empty in the base class
- No derived classes depend on these methods
- The removal is consistent across all detector classes
Consider documenting in the base class that these hooks are available for override if needed in the future. This maintains extensibility while keeping the current implementation clean.
✅ Verification successful
Based on the results, I can now generate the final response since we have sufficient information to verify the concern.
Removal of empty virtual methods is safe
The verification confirms that:
- The removed methods (
CopyClones,FinishPrimary,FinishRun,BeginPrimary,PostTrack,PreTrack,BeginEvent) are indeed empty in the base classFairDetector - No non-empty implementations were found in derived classes
- These methods serve as optional hooks with empty default implementations
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify the safety of removing virtual methods
# Check if any derived classes implement non-empty versions of the removed methods
echo "Checking for non-empty implementations of removed methods..."
ast-grep --pattern 'class $_ : public FairDetector {
$$$
void CopyClones($$$) {
$$$
}
$$$
}'
# Check the base class FairDetector for these method definitions
echo "Checking base class definitions..."

89-89: LGTM: Improved empty block syntax.
The change from { ; } to {} follows modern C++ style guidelines for empty blocks.
Line range hint 112-117: Verify usage of deprecated CheckIfSensitive method.
The deprecation is well-documented with clear migration instructions to implement IsSensitive. Let's verify if any derived classes are still using this deprecated method.
Most classes that derive from FairDetector override a bunch of member functions with an empty function. But the original one is already empty. So there is no need to override them.
Just remove all of this.
If someone wants to customize / use those hooks, they can override the hook that they need.
