Packages that use Constraint

org.modeshape.graph.query	The Query API provides a mechanism for building and executing queries.
org.modeshape.graph.query.model	The Abstract Query Model is a vocabulary that can be used to construct a language-neutral representation of a query.
org.modeshape.graph.query.optimize	This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules.
org.modeshape.graph.query.parse	This package defines the QueryParser interface, which defines a component that can parse a query represented in a specific language and produce the corresponding abstract query model representation.
org.modeshape.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.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.
org.modeshape.graph.request	Sometimes its useful to work with a graph using objects that represent individual commands on the graph.
