Detailed Description

Base class for all measurement plugins.

Notes
-----
This is class is a placeholder for future behavior which will be shared
only between measurement plugins and is implemented for symmetry with the
measurement base plugin configuration class

fail()

def lsst.meas.base.pluginsBase.BasePlugin.fail (   self,   measRecord,   error = None  )

inherited

Record a failure of the `measure` or `measureN` method.

Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
    Table record describing the source being measured.
error : `MeasurementError`, optional
    Only provided if the measurement failed due to a
    `MeasurementError` being raised; otherwise, will be `None`.

Notes
-----
When the plugin raises an exception, framework will call
`BasePlugin.fail` to allow the plugin to set its failure flag
field(s).  When `BasePlugin.measureN` raises an exception,
`BasePlugin.fail` will be called repeatedly with all the records that
were being measured.

If the exception is an `MeasurementError`, it will be passed as the
error argument; in all other cases the error argument will be `None`,
and the failure will be logged by the measurement framework as a
warning.

Reimplemented in lsst.meas.modelfit.psf.psfContinued.GeneralShapeletPsfApproxForcedPlugin, lsst.meas.modelfit.psf.psfContinued.GeneralShapeletPsfApproxSingleFramePlugin, lsst.meas.modelfit.cmodel.cmodelContinued.CModelForcedPlugin, lsst.meas.modelfit.cmodel.cmodelContinued.CModelSingleFramePlugin, lsst.meas.extensions.trailedSources.VeresPlugin.SingleFrameVeresTrailPlugin, lsst.meas.extensions.trailedSources.NaivePlugin.SingleFrameNaiveTrailPlugin, lsst.meas.base.wrappers.GenericPlugin, lsst.meas.base.wrappers.WrappedForcedPlugin, lsst.meas.base.wrappers.WrappedSingleFramePlugin, lsst.meas.base.plugins.SingleFrameSkyCoordPlugin, lsst.meas.base.plugins.SingleFramePeakCentroidPlugin, lsst.meas.base.plugins.InputCountPlugin, lsst.meas.base.plugins.VariancePlugin, lsst.meas.base.plugins.SingleFrameJacobianPlugin, lsst.meas.base.plugins.SingleFrameFPPositionPlugin, lsst.meas.base.footprintArea.CatalogCalculationFootprintAreaPlugin, lsst.meas.base.classification.CatalogCalculationClassificationPlugin, and lsst.ip.diffim.dipoleMeasurement.ClassificationDipolePlugin.

getExecutionOrder()

getTransformClass()

def lsst.meas.base.pluginsBase.BasePlugin.getTransformClass ( )

staticinherited

Get the measurement transformation appropriate to this plugin.

This returns a subclass of `transforms.MeasurementTransform`, which
may be instantiated with details of the algorithm configuration and
then called with information about calibration and WCS to convert from
raw measurement quantities to calibrated units. Calibrated data is
then provided in a separate output table.

Notes
-----
By default, we copy everything from the input to the output without
transformation.
