TypeHandler¶

class telegram.ext.TypeHandler(type, callback, strict=False, block=True)[source]¶

Handler class to handle updates of custom types.

Warning

When setting block to False, you cannot rely on adding custom attributes to telegram.ext.CallbackContext. See its docs for more info.

Parameters:

type (type) – The type of updates this handler should process, as determined by isinstance
callback (coroutine function) –
The callback function for this handler. Will be called when check_update() has determined that an update should be processed by this handler. Callback signature:
```
async def callback(update: object, context: CallbackContext)
```
The return value of the callback is usually ignored except for the special case of telegram.ext.ConversationHandler.
strict (bool, optional) – Use type instead of isinstance. Default is False.
block (bool, optional) –
Determines whether the return value of the callback should be awaited before processing the next handler in telegram.ext.Application.process_update(). Defaults to True.
