## 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.

Uses of ProcessingComponent in org.modeshape.graph

Subclasses of ProcessingComponent in org.modeshape.graph
`protected static class` | `Graph.AccessQueryProcessor`

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

Subclasses of ProcessingComponent in org.modeshape.graph.query.process
`class` | `AbstractAccessComponent` A reusable base class for `ProcessingComponent` implementations that does everything except obtain the correct `Location` objects for the query results.
`class` | `DelegatingComponent`
`class` | `DependentQueryComponent` A `ProcessingComponent` that executes a `dependent query` node by first executing the left component and then executing the right component.
`class` | `DistinctComponent` A `ProcessingComponent` implementation that removes duplicates.
`class` | `DistinctOfSortedComponent` An efficient `ProcessingComponent` that removes duplicates from an already-sorted set of results.
`class` | `ExceptComponent`
`class` | `IntersectComponent`
`class` | `JoinComponent`
`class` | `LimitComponent`
`class` | `MergeJoinComponent` Create a processing component that performs a merge-join algorithm.
`class` | `NestedLoopJoinComponent`
`class` | `NoResultsComponent`
`class` | `ProjectComponent` A `ProcessingComponent` implementation that performs a `PROJECT` operation to reduce the columns that appear in the results.
`class` | `SelectComponent`
`class` | `SetOperationComponent`
`class` | `SortLocationsComponent`
`class` | `SortValuesComponent` A `ProcessingComponent` implementation that performs a `PROJECT` operation to reduce the columns that appear in the results.
`class` | `UnionComponent`

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.

Methods in org.modeshape.graph.query.process with parameters of type ProcessingComponent
`protected static Comparator<Object>` | `JoinComponent.comparatorFor(QueryContext context, ProcessingComponent left, ProcessingComponent right, JoinCondition condition)` Create a `Comparable` that can be used to compare the values required to evaluate the supplied join condition.
`protected static JoinComponent.Joinable` | `JoinComponent.joinableFor(ProcessingComponent left, ProcessingComponent right, JoinCondition condition)` Create a `JoinComponent.ValueSelector` that obtains the value required to use the supplied join condition.
`protected static JoinComponent.ValueSelector` | `JoinComponent.valueSelectorFor(ProcessingComponent source, JoinCondition condition)` Create a `JoinComponent.ValueSelector` that obtains the value required to use the supplied join condition.

Method parameters in org.modeshape.graph.query.process with type arguments of type ProcessingComponent
`protected static boolean` | `SetOperationComponent.unionCompatible(QueryResults.Columns columns, Iterable<ProcessingComponent> sources)`
`protected static Iterable<ProcessingComponent>` | `SetOperationComponent.wrapWithLocationOrdering(Iterable<ProcessingComponent> sources, boolean alreadySorted)` The sources' results must be sorted before the intersection can be computed.
