org.mozilla.javascript.StrictModeHelper

public class StrictModeHelper
extends Object

Helper class for handling strict mode compliance warnings. This class provides utilities to log warnings for strict mode violations that would have been errors in newer versions of Rhino (post 1.7.7.1). To maintain backward compatibility with Rhino 1.7.7.1, strict mode checks added after that version now log warnings instead of throwing errors. The warnings include the full error message that would have been thrown, providing complete information about the violation.

Method Details

warnStrictMode

public static void warnStrictMode(Context cx,
 String messageId,
 Object... args)

Log a strict mode warning instead of throwing an error. This is used for strict mode compliance checks added after Rhino 1.7.7.1.

Parameters:

cx - the current context

messageId - the message ID from Messages.properties

args - optional arguments for the message

warnStrictModeReferenceError

public static void warnStrictModeReferenceError(Context cx,
 String errorMessage)

Log a strict mode warning for ReferenceError violations. Similar to warnStrictMode but specifically for reference errors.

Parameters:

cx - the current context

errorMessage - the complete error message

shouldThrowStrictError

public static boolean shouldThrowStrictError(Context cx)

Check if we should throw an error for strict mode violations. Returns true if FEATURE_STRICT_MODE is enabled AND we're in strict mode. This preserves the old 1.7.7.1 behavior where FEATURE_STRICT_MODE would cause errors to be thrown.

Parameters:

cx - the current context

Returns:

true if errors should be thrown for strict mode violations
