      Does this declaration represents a method? // FIXME: This is never overridden.

    • isArrayLength

      default boolean isArrayLength()
      Does this declaration represent the array length pseudo-field? array.length is the only synthetic pseudo-field defined by the JLS (§10.7). It is a singleton with a fixed name and a fixed type (int), so a dedicated interface would carry no meaningful contract beyond the flag itself. The existing codebase already follows this lighter approach: isVariable() in ResolvedDeclaration has no companion ResolvedVariableDeclaration interface. Introducing an empty marker interface just to be symmetric with isField() / isEnumConstant() would be over-engineering for a one-off case. The fix is therefore: Add default boolean isArrayLength() { return false; } to ResolvedDeclaration Override it to return true inside ArrayLengthValueDeclaration If more extensibility were needed in the future — for instance, to expose getArrayType() to retrieve the component type of the backing array — the right move would be to introduce a ResolvedArrayLengthDeclaration interface at that point. Because all new methods on ResolvedDeclaration are default, and because ArrayLengthValueDeclaration already implements ResolvedValueDeclaration, that refactor could be done without any breaking change.
