Package org.eigenbase.sarg

Provides a class library for representing arguments to index searches, also known as sargs.

See: Description

Interface Summary

Interface	Description
SargExpr	SargExpr represents an expression defining a possibly non-contiguous search subset of a scalar domain of a given datatype.

Class Summary

Class	Description
SargBinding	SargBinding represents the binding of a SargExpr to a particular RexInputRef.
SargEndpoint	SargEndpoint represents an endpoint of a (SargInterval).
SargFactory	SargFactory creates new instances of various sarg-related objects.
SargInterval	SargInterval represents a single contiguous search interval over a scalar domain of a given datatype (including null values).
SargIntervalBase	SargIntervalBase is a common base for SargInterval and SargIntervalExpr.
SargIntervalExpr	SargIntervalExpr represents an expression which can be resolved to a fixed SargInterval.
SargIntervalSequence	SargIntervalSequence represents the union of a set of disjoint SargInterval instances.
SargMutableEndpoint	SargMutableEndpoint exposes methods for modifying a SargEndpoint.
SargRexAnalyzer	SargRexAnalyzer attempts to translate a rex predicate into a SargBinding.
SargSetExpr	SargSetExpr represents the application of a set operator to zero or more child sarg expressions.

Enum Summary

Enum	Description
SargBoundType	SargBoundType defines the possible endpoint boundaries (upper or lower).
SargSetOperator	SargSetOperator defines the supported set operators which can be used to combine instances of SargExpr.
SargStrictness	Defines the boundary strictness of an endpoint: either open (either strictly less than or greater than) or closed (exactly equal).
