BatchCallState
Documentation for eth_defi.event_reader.multicall_batcher.BatchCallState Python class.
- class BatchCallState
Bases:
abc.ABCAllow mutlicall calls to maintain state over the multiple invocations.
Mostly useful for historical mutlticall read and frequency management
Methods summary
__init__()load(data)Persist state across multiple runs
Whether subsequent scheduling needs the completed observation.
save()Persist state across multiple runs.
should_invoke(call, block_identifier, timestamp)Check the condition if this multicall is good to go.
- requires_result_feedback()
Whether subsequent scheduling needs the completed observation.
Consumers must process a complete yielded block before requesting the next result. Legacy states keep their existing buffered behaviour.
- Returns
True when the scheduler must drain its current block buffer.
- Return type
- abstract should_invoke(call, block_identifier, timestamp)
