Detailed Description

Base class for plugin registries.

Notes
-----
The class of plugins allowed in the registry is defined in the constructor
of the registry.

Single-frame and forced plugins have different registries.

Member Function Documentation

makeField()

lsst.meas.base.pluginRegistry.PluginRegistry.makeField	(		self,
			doc,
			default = None,
			optional = False,
			multi = False )

Create a `RegistryField` configuration field from this registry.

Parameters
----------
doc : `str`
    A description of the field.
default : object, optional
    The default target for the field.
optional : `bool`, optional
    When `False`, `lsst.pex.config.Config.validate` fails if the
    field's value is `None`.
multi : `bool`, optional
    A flag to allow multiple selections in the `RegistryField` if
    `True`.
on_none : `Callable`, optional
    A callable that should be invoked when ``apply`` is called but the
    selected name or names is `None`.  Will be passed the field
    attribute proxy (`RegistryInstanceDict`) and then all positional
    and keyword arguments passed to ``apply``.

Returns
-------
field : `lsst.pex.config.RegistryField`
    `~lsst.pex.config.RegistryField` Configuration field.

register()

lsst.meas.base.pluginRegistry.PluginRegistry.register	(		self,
			name,
			PluginClass,
			shouldApCorr = False,
			apCorrList = () )

Register a plugin class with the given name.

Parameters
----------
name : `str`
    The name of the plugin. This is used as a prefix for all fields
    produced by the plugin, and it should generally contain the name
    of the plugin or algorithm class itself as well as enough of the
    namespace to make it clear where to find the code.  For example
    ``base_GaussianFlux`` indicates an algorithm in `lsst.meas.base`
    that measures Gaussian Flux and produces fields such as
    ``base_GaussianFlux_instFlux``, ``base_GaussianFlux_instFluxErr``
    and ``base_GaussianFlux_flag``.
shouldApCorr : `bool`
    If `True`, then this algorithm measures an instFlux that should
    be aperture corrected. This is shorthand for ``apCorrList=[name]``
    and is ignored if ``apCorrList`` is specified.
apCorrList : `list` of `str`
    List of field name prefixes for instFlux fields to be aperture
    corrected.  If an algorithm produces a single instFlux that should
    be aperture corrected then it is simpler to set
    ``shouldApCorr=True``. But if an algorithm produces multiple such
    fields then it must specify ``apCorrList`` instead. For example,
    ``modelfit_CModel`` produces three such fields:
    ``apCorrList=("modelfit_CModel_exp", "modelfit_CModel_exp",
    "modelfit_CModel_def")``. If ``apCorrList`` is not empty then
    shouldApCorr is ignored.

Notes
-----
The same plugin may be registered multiple times with different names;
this can be useful if we often want to run it multiple times with
different configuration.
