Uses of OptimizerRule in org.modeshape.jcr.query.optimize

Classes in org.modeshape.jcr.query.optimize that implement OptimizerRule

Modifier and Type	Class and Description
class	AddAccessNodes An optimizer rule that inserts an ACCESS above each SOURCE leaf node in a query plan.
class	AddIndexes A rule that adds indexes below PlanNode.Type.SOURCE nodes.
class	AddJoinConditionColumnsToSources An OptimizerRule that adds any missing columns required by the join conditions to the appropriate join source.
class	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.
class	ChooseJoinAlgorithm An optimizer rule that choose the appropriate join algorithm and sets up any prerequisites, based upon the JoinCondition.
class	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.
class	JoinOrder An optimization rule that ensure that the order of the left and right side of a JOIN match certain join criteria, including DescendantNodeJoinCondition and ChildNodeJoinCondition.
class	OrderIndexesByCost
class	PushProjects This rule attempts to ensure the proper location of PlanNode.Type.PROJECT nodes.
class	PushSelectCriteria An optimizer rule that attempts to push the criteria nodes in a canonical plan down as far as possible.
class	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.
class	RaiseVariableName An optimizer rule that moves up higher in the plan any variable name property to the node immediately under a dependent query node.
class	RemoveEmptyAccessNodes An optimizer rule that removes any ACCESS nodes that are known to never return any tuples because of conflicting constraints.
class	ReorderSortAndRemoveDuplicates An optimizer rule that looks for a PlanNode.Type.SORT plan node below a PlanNode.Type.DUP_REMOVE, and swaps them.
class	ReplaceViews An optimizer rule that replaces any SOURCE nodes that happen to be views.
class	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.
class	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).
class	RewritePathAndNameCriteria An optimizer rule that rewrites Constraint trees, moving path-, name-, or depth-oriented criteria to the left-most parts of the constraint tree.
class	RewritePseudoColumns Changes any criteria that writes criteria containing pseudo-columns into standard criteria.
class	RightOuterToLeftOuterJoins An optimizer rule that converts right outer joins into left outer joins.
