Workspace

class lsst.ap.verify.Workspace(location)

Bases: object

A directory used by ap_verify to handle data and outputs.

Any object of this class represents a working directory containing (possibly empty) subdirectories for various purposes. Subclasses are typically specialized for particular workflows. Keeping such details in separate classes makes it easier to provide guarantees without forcing awkward directory structures on users.

All Workspace classes must guarantee the existence of any subdirectories inside the workspace. Directories corresponding to repositories do not need to be initialized, since creating a valid repository usually requires external information.

Parameters:

locationstr

The location on disk where the workspace will be set up. Will be created if it does not already exist.

Raises:

EnvironmentError

Raised if location is not readable or not writeable

Attributes Summary

alertLocation	The absolute location of an output directory for persisted alert packets (str, read-only).
analysisButler	A Butler that can read pipeline outputs (read-only).
configDir	The absolute location of a directory containing custom Task config files for use with the data (str, read-only).
dbLocation	The default absolute location of the source association database to be created or updated by the pipeline (str, read-only).
workButler	A Butler that can produce pipeline inputs and outputs (read-only).
workDir	The absolute location of the workspace as a whole (str, read-only).

Methods Summary

mkdir(directory)

Create a directory for the workspace.

Attributes Documentation

alertLocation

The absolute location of an output directory for persisted alert packets (str, read-only).

analysisButler

A Butler that can read pipeline outputs (read-only). The type is class-dependent.

The Butler should be read-only, if its type supports the restriction.

configDir

The absolute location of a directory containing custom Task config files for use with the data (str, read-only).

dbLocation

The default absolute location of the source association database to be created or updated by the pipeline (str, read-only).

Shall be a pathname to a database suitable for the backend of Apdb.

workButler

A Butler that can produce pipeline inputs and outputs (read-only). The type is class-dependent.

workDir

The absolute location of the workspace as a whole (str, read-only).

Methods Documentation

static mkdir(directory)

Create a directory for the workspace.

This method is intended to be called only by subclasses, and should not be used by external code.

Parameters:

directorystr
