Description

Class Summary

ConcurrentOperatorsBucket	An object of ConcurrentOperatorsBucket contains multiple statistical operators that can be executed in parallel.
DataMovementOperator	A Data Movement Operator (DMO) is a bridge from physical database objects (e.g., view, relational table etc.) to logical requirements of the data.
ExecutionPlan	The class of an execution plan, which is an ordered list of ConcurrentOperatorsBucket with parameters.
FelixClause	The clause object used in Felix, which extends the Clause class in Tuffy to contain Felix-related fields and methods.
FelixPredicate	The predicate object used in Felix, which extends the Predicate class in Tuffy to contain Felix-related fields and methods.
FelixQuery	An object of FelixQuery consists of program, query and evidence from inputs.
OperatorBucketGraph	The class of an OperatorBucketGraph.
StatOperator	Abstract class of a statistical operator (e.g., Tuffy, Coref, CRF etc.

Enum Summary

FelixPredicate.FPProperty	Properties that can be assigned to each predicate.
StatOperator.OPType	Type of StatOperator.

Package felix.dstruct Description

Package that contains the basic data structure used by Felix. There are two groups of data structures:

• Structures used in Felix's execution plan. This includes execution plans, operator buckets, and operators. An execution plan consists of a list of operator buckets. Each operator bucket is made up of one or more operators which may be data movement operators (DMOs) or statistical operators (COREF, CRF, LR, TUFFY).
• Structures used for Felix's input. This includes clauses, predicates, and queries. These structures are extended from the corresponding structures in Tuffy.
