wrapSingleFrameAlgorithm

lsst.meas.base.wrapSingleFrameAlgorithm(AlgClass, executionOrder, name=None, needsMetadata=False, hasMeasureN=False, hasLogName=False, **kwds)

Expose a C++ SingleFrameAlgorithm class as a measurement plugin.

Parameters:

AlgClassAPI compatible with SingleFrameAlgorithm

C++ algorithm class to convert. May either derive directly from SingleFrameAlgorithm or be an unrelated class which has the same measure, measureN and fail signatures.

executionOrderfloat

The order this plugin should be run, relative to others (see BasePlugin.getExecutionOrder).

namestr, optional

Name to use when registering the algorithm. Ignored if doRegistry=False; set to generateAlgorithmName(AlgClass) if None.

needsMetadatabool, optional

Sets whether the AlgClass’s constructor should be passed a PropertySet metadata argument.

hasMeasureNbool, optional

Does the algorithm support simultaneous measurement of multiple sources? If True, a bool doMeasureN field will be added to the generated config class, and its value will be passed as the last argument when calling the AlgClass constructor.

hasLogNamebool, optional

True if the C++ algorithm supports logName as a constructor argument.

**kwds

Additional keyword arguments are passed to the lower-level wrapAlgorithm and wrapAlgorithmControl classes.

Returns:

singleFramePluginsubclass of SingleFramePlugin

The new measurement plugin class.

Notes

The first three arguments to the C++ constructor are expected to be Control const & ctrl, std::string const & name, Schema & schema.

If needsMetadata is True, we also append PropertySet & metadata.

If hasMeasureN is True, we also append bool doMeasureN.

If hasLogName is True, we also append std::string logName.

If more than one of the above is True, the metadata PropertySet precedes the doMeasureN bool and the logName comes last of the three.
