Packages that use IBindingProducerNode

Package	Description
com.bigdata.rdf.sparql.ast	This package contains an Abstract Syntax Tree which provides an intermediate translation target for SPARQL parsers.
com.bigdata.rdf.sparql.ast.service	This package provides support for SPARQL 1.1 Federated Query, including the special case of "service" end points which live within the same JVM and use direct method calls rather than SPARQL Query and remote (HTTP) end points for which we will generate an appropriate SPARQL query.

Uses of IBindingProducerNode in com.bigdata.rdf.sparql.ast

Subinterfaces of IBindingProducerNode in com.bigdata.rdf.sparql.ast

Modifier and Type	Interface and Description
interface	IJoinNode A marker interface for any kind of AST Node which joins stuff.
interface	IReorderableNode Interface for things which can be re-ordered by the static join optimizer.

Classes in com.bigdata.rdf.sparql.ast that implement IBindingProducerNode

Modifier and Type	Class and Description
class	ArbitraryLengthPathNode A special kind of AST node that represents the SPARQL 1.1 arbitrary length path operator.
class	AssignmentNode AST node models the assignment of a value expression to a variable
class	BindingsClause The solutions declared by a BINDINGS clause.
class	GraphPatternGroup<E extends IGroupMemberNode> Join group or union.
class	JoinGroupNode An optional or non-optional collection of query nodes that run together in a group.
class	NamedSubqueryInclude An AST node which provides a reference in an IGroupNode and indicates that a named solution set should be joined with the solutions in the group.
class	NamedSubqueryRoot A subquery with a named solution set which can be referenced from other parts of the query.
class	PropertyPathNode A node in the AST representing a triple pattern with a property path.
class	PropertyPathUnionNode This node is purely to trick the ASTJoinOrderByTypeOptimizer - we need to keep the property path stuff in the right order, even the UNIONs.
class	QueryBase Contains the projection clause, where clause, and solution modified clauses.
class	QueryRoot The top-level Query.
class	StatementPatternNode A node in the AST representing a statement pattern.
class	SubqueryBase AST node for subqueries.
class	SubqueryRoot A SPARQL 1.1 style subquery.
class	UnionNode A special kind of group IGroupNode that represents the sparql union operator.
class	ZeroLengthPathNode Deprecated. Does not work - leads to cardinality problems and can be removed. Zero Length Paths are integrated into the ALP node / ArbitraryLengthPathOp now.
