Detailed Description

Base configuration for all measurement driver tasks.

Parameters
----------
ignoreSlotPluginChecks : `bool`, optional
    Do not check that all slots have an associated plugin to run when
    validating this config. This is primarily for tests that were written
    before we made Tasks always call `config.validate()` on init.
    DEPRECATED DM-35949: this is a temporary workaround while we better
    define how config/schema validation works for measurement tasks.

Examples
--------
Subclasses should define the 'plugins' and 'undeblended' registries, e.g.

.. code-block:: py

    plugins = PluginBaseClass.registry.makeField(
        multi=True,
        default=[],
        doc="Plugins to be run and their configuration"
    )
    undeblended = PluginBaseClass.registry.makeField(
        multi=True,
        default=[],
        doc="Plugins to run on undeblended image"
    )

where ``PluginBaseClass`` is the appropriate base class of the plugin
(e.g., `SingleFramePlugin` or `ForcedPlugin`).

Member Function Documentation

__new__()

lsst.meas.base.baseMeasurement.BaseMeasurementConfig.__new__	(		cls,
		*	args,
			kw = False,
		**	kwargs )

Allocate a new `lsst.pex.config.Config` object.

In order to ensure that all Config object are always in a proper state
when handed to users or to derived `~lsst.pex.config.Config` classes,
some attributes are handled at allocation time rather than at
initialization.

This ensures that even if a derived `~lsst.pex.config.Config` class
implements ``__init__``, its author does not need to be concerned about
when or even the base ``Config.__init__`` should be called.

Reimplemented from lsst.pex.config.config.Config.

Definition at line 171 of file baseMeasurement.py.

    def __new__(cls, *args, ignoreSlotPluginChecks=False, **kwargs):
        instance = super().__new__(cls, *args, **kwargs)
        if ignoreSlotPluginChecks:
            msg = ("ignoreSlotPluginChecks is deprecated and should only be used in tests."
                   " No removal date has been set; see DM-35949.")
            warnings.warn(msg, category=FutureWarning, stacklevel=2)
        object.__setattr__(instance, "_ignoreSlotPluginChecks", ignoreSlotPluginChecks)
        return instance
 

validate()

lsst.meas.base.baseMeasurement.BaseMeasurementConfig.validate

(

self

)

Validate the Config, raising an exception if invalid.

Raises
------
lsst.pex.config.FieldValidationError
    Raised if verification fails.

Notes
-----
The base class implementation performs type checks on all fields by
calling their `~lsst.pex.config.Field.validate` methods.

Complex single-field validation can be defined by deriving new Field
types. For convenience, some derived `lsst.pex.config.Field`-types
(`~lsst.pex.config.ConfigField` and
`~lsst.pex.config.ConfigChoiceField`) are defined in
``lsst.pex.config`` that handle recursing into subconfigs.

Inter-field relationships should only be checked in derived
`~lsst.pex.config.Config` classes after calling this method, and base
validation is complete.

Reimplemented from lsst.pex.config.config.Config.

            raise ValueError("source shape slot algorithm '%s' is not being run." % self.slots.shape)
        for slot in (self.slots.psfFlux, self.slots.apFlux, self.slots.modelFlux,

                    if len(name) <= len(slot) and name == slot[:len(name)]:
                        break
                else:
                    raise ValueError("source instFlux slot algorithm '%s' is not being run." % slot)
