IDBError MemoryObjectStore::deleteIndex(MemoryBackingStoreTransaction& transaction, uint64_t indexIdentifier)
{
    LOG(IndexedDB, "MemoryObjectStore::deleteIndex");

        return IDBError(IDBDatabaseException::ConstraintError);

    m_info.deleteIndex(indexIdentifier);
    transaction.indexDeleted(*index);

    return { };
}

Example #2

{
    LOG(IndexedDB, "MemoryObjectStore::deleteIndex");

Example #4
