Class RedundantOverrideOrError

java.lang.Object

org.ek9lang.compiler.phase5.RedundantOverrideOrError

All Implemented Interfaces:

Consumer<org.antlr.v4.runtime.tree.ParseTree>

final class RedundantOverrideOrError
extends Object
implements Consumer<org.antlr.v4.runtime.tree.ParseTree>

Detects when an override method/operator body is textually identical to the super (E11044).

A redundant override adds no value - the inherited implementation already provides identical behaviour. This typically occurs from copy-paste or AI-generated code.

This checker operates in two phases per method:

1. Store a body fingerprint on every method with a body (as squirrelled data)
2. For override methods, compare fingerprint with the super method's fingerprint

Exemptions (override is NOT flagged as redundant):

• Defaulted (compiler-generated) methods/operators
• Externally implemented (Java-backed) methods
• Abstract methods (no body to compare)
• Overrides compelled by trait method conflicts (E06150)
