[BUG][code-analyzer] sfge: calling toString() on an enum aborts the entry point (UnimplementedMethodException)

ApexEnumValue.java の 123 行目付近から始め、PathScopeVisitor.java まで、示されている処理を追跡します。提供されている sf code-analyzer コマンドを EnumToString の再現コードに対して実行します。完了の条件は、enum toString() がエントリポイントを中断せず、適切に確定値または不確定値を返し、カバレッジを失わずに解析が完了することです。

Have you tried to resolve this issue yourself first?

• I confirm I have gone through the above steps and still have an issue to report.

Bug Description

Engine: sfge (Salesforce Graph Engine) · Rule: ApexFlsViolation (DevPreview) · Selector: --rule-selector sfge

ApexEnumValue.apply implements only name(), ordinal() and (when indeterminate) equals(), then falls through to throw new UnimplementedMethodException(this, vertex) at ApexEnumValue.java:123.

toString() is universal in Apex — every enum inherits it — so any path that calls it on an enum value aborts.

Schema.DisplayType dt = Account.Name.getDescribe().getType();
a.Description = dt.toString();

Output / Logs

UnimplementedMethodException: ApexEnumValue:toString, vertex=MethodCallExpressionVertex{fullMethodName=dt.toString, ...}:
com.salesforce.graph.symbols.apex.ApexEnumValue.apply(ApexEnumValue.java:123);
com.salesforce.graph.symbols.PathScopeVisitor.handleApexValueMethod(PathScopeVisitor.java:1487);
com.salesforce.graph.symbols.PathScopeVisitor.afterVisit(PathScopeVisitor.java:1242); ...

Steps To Reproduce

1. Create an empty SFDX project (sfdx-project.json with a single force-app package directory).
2. Add force-app/main/default/classes/EnumToString.cls with the class shown below, plus a standard EnumToString.cls-meta.xml (apiVersion 62.0).
3. Add code-analyzer.yml:

   engines:
     sfge:
       java_thread_timeout: 900000
       java_thread_count: 4
   

4. Run:

   sf code-analyzer run --rule-selector sfge --workspace . --config-file code-analyzer.yml
   

5. The run reports an InternalExecutionError for the entry point instead of analysing it. That entry point yields no ApexFlsViolation findings at all, and nothing in the summary indicates coverage was lost.

public with sharing class EnumToString {
    @AuraEnabled
    public static void run() {
        Schema.DisplayType dt = Account.Name.getDescribe().getType();
        Account a = new Account();
        a.Description = dt.toString();
        insert a;
    }
}

Expected Behavior

toString() on an enum should resolve like name() does — returning the value name when determinate, and an indeterminate string otherwise. Suggested fix: handle toString alongside METHOD_NAME in ApexEnumValue.apply, and add it to INDETERMINANT_VALUE_PROVIDERS.

More generally, an unmodelled method on a known value type should degrade to an indeterminate value rather than abort the entry point.

Additional Context (Screenshots, Files, etc)

In our codebase this accounts for 8 occurrences across 4 distinct @AuraEnabled entry points — the highest count of any single unimplemented-method signature we hit.

Same class of gap as #1510, #1044 and #1003 (all on ApexStringValue), which were closed in the 2026-06-30 pre-v5 sweep.

Workaround

Replace enumValue.toString() with enumValue.name(), which sfge does model. Semantically equivalent for standard enums.

Urgency

Moderate
