lsst.pex.config¶
The lsst.pex.config module provides a configuration system for the LSST Science Pipelines.
The lsst.pex.config.Config class is an integral part of the task framework (see lsst.pipe.base), though lsst.pex.config is also useful on its own.
Configuration parameters can be validated, documented, and even record the history of their values for provenance.

compareScalars(name, v1, v2, output[, rtol, …]) |
Compare two scalar values for equality. |
getComparisonName(name1, name2) |
Create a comparison name that is used for printed output of comparisons. |
makeConfigClass(ctrl[, name, base, doc, …]) |
Create a Config class that matches a C++ control object class. |
makePropertySet(config) |

registerConfigurable(name, registry[, …]) |
A decorator that adds a class as a configurable in a Registry instance. |
wrap(ctrl) |
Decorator that adds fields from a C++ control class to a lsst.pex.config.Config class. |
Classes¶
ChoiceField(doc, dtype, allowed[, default, …]) |

ConfigurableField(doc, target[, …]) |
A configuration field (Field subclass) that can be can be retargeted towards a different configurable (often a lsst.pipe.base.Task subclass). |
ConfigurableInstance(config, field[, at, label]) |
A retargetable configuration in a ConfigurableField that proxies a Config. |
DictField(doc, keytype, itemtype[, default, …]) |
A configuration field (Field subclass) that maps keys and values. |
Field(doc, dtype[, default, check, …]) |
A field in a Config that supports int, float, complex, bool, and str data types. |
FieldValidationError(field, config, msg) |
Raised when a ~lsst.pex.config.Field is not valid in a particular ~lsst.pex.config.Config. |
ListField(doc, dtype[, default, optional, …]) |
A configuration field (Field subclass) that contains a list of values of a specific type. |
RangeField(doc, dtype[, default, optional, …]) |
A configuration field (lsst.pex.config.Field subclass) that requires the value to be in a specific numeric range. |
Registry([configBaseType]) |
A base class for global registries, which map names to configurables. |
RegistryField(doc, registry[, default, …]) |
