Memory “detector” reference

class libertem_live.detectors.memory.MemoryAcquisition(conn: MemoryConnection, nav_shape: tuple[int, ...], frames_per_partition: int = 128, pending_aq: PendingMemAq | None = None, controller: None = None, hooks: Hooks | None = None)

An acquisition based on memory

Currently it just splices the additional functionality from AcquisitionMixin into the MemoryDataSet using multiple inheritance and implements a dummy for the acquire() context manager.

Examples

>>> import numpy as np
>>> from libertem_live.api import Hooks
...
>>> data = np.random.random((23, 42, 51, 67))
...
>>> class MyHooks(Hooks):
...     def on_ready_for_data(self, env):
...         print(f"Triggering! {env.aq.shape.nav}")
...
>>> conn = ctx.make_connection('memory').open(
...    data=data
... )
...
>>> aq = ctx.make_acquisition(
...     conn=conn,
...     hooks=MyHooks(),
... )
...
>>> udf = SumUDF()
>>> ctx.run_udf(dataset=aq, udf=udf, plots=True)
