simulate_alert

lsst.alert.packet.simulate_alert(schema, keepNull=None, arrayCount=None)

Parse the schema and generate a compliant alert with random contents.

Parameters

schemadict

Schema to which to conform. Should be fully resolved (i.e., not contain any references to special LSST types).

keepNull{list of str, None}

Schema keys for which to output null values.

arrayCount{dict, None}

Number of array items to randomly generate for each provided schema key.

Returns

outputdict

Packet with random values corresponding to provided schema.

Notes

keepNull and arrayCount expect schema keys without namespaces (e.g., 'diaSourceId', not 'lsst.alert.diaSource.diaSourceId'. This is sufficient because our schemas have unique keys but is not fully general.

Todo

This should accept an instance of lsst.alert.Schema and do whatever resolution is necessary internally.
