org.jboss.dna.graph.query.model.Constraint

Packages that use Constraint

org.jboss.dna.graph.query.model	The Abstract Query Model is a vocabulary that can be used to construct a language-neutral representation of a query.
org.jboss.dna.graph.query.plan	This package defines the Planner interface, the CanonicalPlanner implementation, and the PlanNode class that is used to represent a canonical query plan.
org.jboss.dna.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.
org.jboss.dna.graph.request	Sometimes its useful to work with a graph using objects that represent individual commands on the graph.

Uses of Constraint in org.jboss.dna.graph.query.model

Subclasses of Constraint in org.jboss.dna.graph.query.model

class	And A constraint that evaluates to true when both of the other constraints evaluate to true.
class	Between A constraint that evaluates to true when the value defined by the dynamic operand evaluates to be within the specified range.
class	ChildNode A constraint requiring that the selected node is a child of the node reachable by the supplied absolute path
class	Comparison A constraint that evaluates to true when the defined operation evaluates to true.
class	DescendantNode A constraint requiring that the selected node is a descendant of the node reachable by the supplied absolute path
class	FullTextSearch A constraint that evaluates to true only when a full-text search applied to the search scope results in positive findings.
class	Not A constraint that negates another constraint.
class	Or A constraint that evaluates to true when either of the other constraints evaluates to true.
class	PropertyExistence A constraint that evaluates to true only when a named property exists on a node.
class	SameNode A constraint requiring that the selected node is reachable by the supplied absolute path
class	SetCriteria A constraint that evaluates to true when the defined operation evaluates to true.

Methods in org.jboss.dna.graph.query.model that return Constraint

Constraint	Query.getConstraint() Get the constraints, if there are any.
Constraint	Not.getConstraint() The constraint being negated.
Constraint	Or.getLeft() Get the left-hand constraint.
Constraint	And.getLeft() Get the constraint that is on the left-hand-side of the AND operation.
Constraint	Or.getRight() Get the right-hand constraint.
Constraint	And.getRight() Get the constraint that is on the right-hand-side of the AND operation.

Methods in org.jboss.dna.graph.query.model with parameters of type Constraint

Query

Query.constrainedBy(Constraint constraint) Create a copy of this query, but one that uses the supplied constraint.
