Member Function Documentation

equals()

virtual bool gtsam::ConcurrentSmoother::equals ( const ConcurrentSmoother &  rhs, double  tol = 1e-9  ) const

pure virtual

Check if two Concurrent Smoothers are equal.

Implemented in gtsam::ConcurrentBatchSmoother, and gtsam::ConcurrentIncrementalSmoother.

getSummarizedFactors()

virtual void gtsam::ConcurrentSmoother::getSummarizedFactors ( NonlinearFactorGraph &  summarizedFactors, Values &  separatorValues  )

pure virtual

Populate the provided containers with factors that constitute the smoother branch summarization needed by the filter.

Parameters

summarizedFactors	The summarized factors for the filter branch
separatorValues	The linearization points of the separator variables

Implemented in gtsam::ConcurrentBatchSmoother, and gtsam::ConcurrentIncrementalSmoother.

postsync()

virtual void gtsam::ConcurrentSmoother::postsync ( )

inlinevirtual

Perform any required operations after the synchronization process finishes.

Called by 'synchronize'

Reimplemented in gtsam::ConcurrentBatchSmoother, and gtsam::ConcurrentIncrementalSmoother.

presync()

virtual void gtsam::ConcurrentSmoother::presync ( )

inlinevirtual

Perform any required operations before the synchronization process starts.

Called by 'synchronize'

Reimplemented in gtsam::ConcurrentBatchSmoother, and gtsam::ConcurrentIncrementalSmoother.

print()

virtual void gtsam::ConcurrentSmoother::print ( const std::string &  s = "Concurrent Smoother:\n", const KeyFormatter &  keyFormatter = DefaultKeyFormatter  ) const

pure virtual

Implement a standard 'print' function.

Implemented in gtsam::ConcurrentBatchSmoother, and gtsam::ConcurrentIncrementalSmoother.

synchronize()

virtual void gtsam::ConcurrentSmoother::synchronize ( const NonlinearFactorGraph &  smootherFactors, const Values &  smootherValues, const NonlinearFactorGraph &  summarizedFactors, const Values &  rootValues  )

pure virtual

Apply the new smoother factors sent by the filter, and the updated version of the filter branch summarized factors.

Parameters

smootherFactors	A set of new factors added to the smoother from the filter
smootherValues	Linearization points for any new variables
summarizedFactors	An updated version of the filter branch summarized factors
rootValues	The linearization point of the root variables

Implemented in gtsam::ConcurrentBatchSmoother, and gtsam::ConcurrentIncrementalSmoother.
