com.bigdata.rdf.sparql.ast.GraphPatternGroup

Packages that use GraphPatternGroup

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.eval
com.bigdata.rdf.sparql.ast.optimizers
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 GraphPatternGroup in com.bigdata.rdf.sparql.ast

Subclasses of GraphPatternGroup in com.bigdata.rdf.sparql.ast

Modifier and Type	Class and Description
class	JoinGroupNode An optional or non-optional collection of query nodes that run together in a group.
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	UnionNode A special kind of group IGroupNode that represents the sparql union operator.
