An Analysis
object is the sole argument to the app
function in your app.py
module. Its attributes include
every strand that can be possibly added to a Twine
, although only the strands specified in your twine.py
file
will not be None
. The attributes are:
input_values
input_manifest
configuration_values
configuration_manifest
output_values
output_manifest
credentials
children
monitors
Additionally, all input and configuration attributes are hashed using a BLAKE3 hash so the inputs and configuration that produced a given output in your app can always be verified. These hashes exist on the following attributes:
input_values_hash
input_manifest_hash
configuration_values_hash
configuration_manifest_hash
If a strand is None
, so will its corresponding hash attribute be. The hash of a datafile is the hash of
its file, while the hash of a manifest or dataset is the cumulative hash of the files it refers to.
