Uses of Package
org.modeshape.jcr.query.optimize

Packages that use org.modeshape.jcr.query.optimize

org.modeshape.jcr.query.lucene	The core query engine, which currently uses Lucene for indexing and raw queries, and the Hibernate Search engine (which does not depend on or use Hibernate Core or JPA) for updating and querying the Lucene indexes.
org.modeshape.jcr.query.optimize	This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules.
org.modeshape.jcr.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.

Optimizer
Interface for an optimizer.

AddAccessNodes
An optimizer rule that inserts an ACCESS above each SOURCE leaf node in a query plan.

AddJoinConditionColumnsToSources
An OptimizerRule that adds any missing columns required by the join conditions to the appropriate join source.

AddOrderingColumnsToSources
An OptimizerRule that adds any missing columns required by the ordering specifications to the SORT node's PROJECT, and to the appropriate access nodes.

ChooseJoinAlgorithm
An optimizer rule that choose the appropriate join algorithm and sets up any prerequisites, based upon the JoinCondition.

CopyCriteria
An optimizer rule that copies SELECT nodes that apply to one side of a equi-join condition so that they also apply to the other side fo the equi-join condition.

Optimizer
Interface for an optimizer.

OptimizerRule
Interface that defines an Optimizer rule.

PushProjects
This rule attempts to ensure the proper location of PlanNode.Type.PROJECT nodes.

PushSelectCriteria
An optimizer rule that attempts to push the criteria nodes in a canonical plan down as far as possible.

RaiseSelectCriteria
An optimizer rule that moves up higher in the plan any SELECT node that appears below a JOIN node and that applies to selectors that are on the other side of the join.

RaiseVariableName
An optimizer rule that moves up higher in the plan any variable name property to the node immediately under a dependent query node.

RemoveEmptyAccessNodes
An optimizer rule that removes any ACCESS nodes that are known to never return any tuples because of conflicting constraints.

ReplaceViews
An optimizer rule that replaces any SOURCE nodes that happen to be views.

RewriteAsRangeCriteria
An optimizer rule that rewrites two AND-ed Constraints that constraint a dynamic operand to a range of values as a single Between constraint.

RewriteIdentityJoins
An optimizer rule that rewrites JOIN nodes that have equi-join criteria where the columns involved in the equi-join are all identity columns (that is, they form a key for the table).

RewritePathAndNameCriteria
An optimizer rule that rewrites Constraint trees, moving path-, name-, or depth-oriented criteria to the left-most parts of the constraint tree.

RewritePseudoColumns
An optimizer rule that moves up higher in the plan any variable name property to the node immediately under a dependent query node.

RightOuterToLeftOuterJoins
An optimizer rule that converts right outer joins into left outer joins.
