Uses of Class
org.modeshape.graph.query.process.ProcessingComponent

Packages that use ProcessingComponent

org.modeshape.graph	The ModeShape Graph API defines the types that allow you to work with content organized as a graph.
org.modeshape.graph.query.process	This package defines the QueryProcessor interface, which is responsible for constructing for each query a tree of ProcessingComponent objects that each are responsible for processing a specific aspect of the query and returning the tuples to the parent component.

Methods in org.modeshape.graph.query.process that return ProcessingComponent

protected abstract ProcessingComponent	QueryProcessor.createAccessComponent(QueryCommand originalQuery, QueryContext context, PlanNode accessNode, QueryResults.Columns resultColumns, SelectComponent.Analyzer analyzer) Create the ProcessingComponent that processes a single PlanNode.Type.ACCESS branch of a query plan.
protected ProcessingComponent	QueryProcessor.createComponent(QueryCommand originalQuery, QueryContext context, PlanNode node, QueryResults.Columns columns, SelectComponent.Analyzer analyzer) Method that is called to build up the ProcessingComponent objects that correspond to the optimized query plan.
protected ProcessingComponent	DelegatingComponent.delegate() Get the delegate processor.
protected ProcessingComponent	JoinComponent.left() Get the processing component that serves as the left side of the join.
protected ProcessingComponent	DependentQueryComponent.left() Get the processing component that serves as the left side of the join.
protected ProcessingComponent	JoinComponent.right() Get the processing component that serves as the right side of the join.
protected ProcessingComponent	DependentQueryComponent.right() Get the processing component that serves as the right side of the join.

Methods in org.modeshape.graph.query.process that return types with arguments of type ProcessingComponent

protected Iterable<ProcessingComponent>	SetOperationComponent.sources()
protected static Iterable<ProcessingComponent>	SetOperationComponent.wrapWithLocationOrdering(Iterable<ProcessingComponent> sources, boolean alreadySorted) The sources' results must be sorted before the intersection can be computed.
