Implementations fetch content from various origins (local files, remote APIs, databases) and return unified ContentEntry objects. Subclasses must implement: source_type property fetch_all() async generator fetch_one() async method Inherits from ABC Methods 8 Tag source_type property Return source type identifier. str Caret Right def source_type(self) -> str Return source type identifier. Returns str — String identifier like 'local', 'github', 'notion', 'rest' fetch_all async Fetch all content entries from this source. 0 AsyncIterator[Conte… Caret Right async def fetch_all(self) -> AsyncIterator[ContentEntry] Fetch all content entries from this source. Returns AsyncIterator[ContentEntry] fetch_one async Fetch a single content entry by ID. 1 ContentEntry | None Caret Right async def fetch_one(self, id: str) -> ContentEntry | None Fetch a single content entry by ID. Parameters 1 id str Source-specific identifier (e.g., file path, doc ID) Returns ContentEntry | None — ContentEntry if found, None otherwise get_cache_key Generate cache key for this source configuration. Used to invalidate cache whe… 0 str Caret Right def get_cache_key(self) -> str Generate cache key for this source configuration. Used to invalidate cache when config changes. Override for custom cache key logic. Returns str — 16-character hex string based on config hash get_last_modified async Get last modification time for the entire source. Used for cache invalidation.… 0 datetime | None Caret Right async def get_last_modified(self) -> datetime | None Get last modification time for the entire source. Used for cache invalidation. Returns None if unknown or not supported. Returns datetime | None — Last modification datetime or None is_changed async Check if source content has changed since last fetch. 1 bool Caret Right async def is_changed(self, cached_checksum: str | None) -> bool Check if source content has changed since last fetch. Parameters 1 cached_checksum str | None Previously cached checksum Returns bool — True if content may have changed, False if definitely unchanged fetch_all_sync Synchronous wrapper for fetch_all(). Runs the async generator in a new event loop. 0 Iterator[ContentEntry] Caret Right def fetch_all_sync(self) -> Iterator[ContentEntry] Synchronous wrapper for fetch_all(). Runs the async generator in a new event loop. Returns Iterator[ContentEntry] fetch_one_sync Synchronous wrapper for fetch_one(). 1 ContentEntry | None Caret Right def fetch_one_sync(self, id: str) -> ContentEntry | None Synchronous wrapper for fetch_one(). Parameters 1 id str Source-specific identifier Returns ContentEntry | None — ContentEntry if found, None otherwise Internal Methods 2 Caret Right __init__ Initialize content source. 2 None Caret Right def __init__(self, name: str, config: dict[str, Any]) -> None Initialize content source.
