Interface Summary

Interface	Description
Evidence	Represents the evidence, or case data (e.g.
Inference	The interface for a Bayesian network inference algorithm, which is used to perform queries such as calculating posterior probabilities and log-likelihood values for a case.
InferenceFactory	Uses the factory design pattern to create inference related objects for inference algorithms.
QueryDistributionCollection	The collection of distributions to be calculated by a Inference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput).
QueryFunctionCollection	Collection of functions to be evaluated at query time, after any query distributions have been calculated.
QueryOptions	Options that govern the calculations performed by Inference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput).
QueryOutput	Returns any information, in addition to the distributions, that is requested from a query.
QuerySamplingOptions	Interface for approximate sampling inference algorithms, which can be implemented in addition to QueryOptions.
