Packages that use Visitable | |
---|---|
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.optimize | This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules. |

Classes in org.jboss.dna.graph.query.model that implement Visitable | |
---|---|
class |
AllNodes
A selector that represents a source that returns all nodes. |
class |
And
A constraint that evaluates to true when both of the other constraints evaluate to true. |
class |
ArithmeticOperand
A dynamic operand that represents a (binary) arithmetic operation upon one or more other operands, used in Comparison
and Ordering components. |
class |
Between
A constraint that evaluates to true when the value defined by the dynamic operand evaluates to be within the specified range. |
class |
BindVariableName
A value bound to a variable name used in a Comparison constraint. |
class |
ChildNode
A constraint requiring that the selected node is a child of the node reachable by the supplied absolute path |
class |
ChildNodeJoinCondition
A join condition that evaluates to true only when the named child node is indeed a child of the named parent node. |
class |
Column
|
class |
Command
Represents the abstract base class for all top-level language objects that are the root of a language object tree. |
class |
Comparison
A constraint that evaluates to true when the defined operation evaluates to true. |
class |
Constraint
|
class |
DescendantNode
A constraint requiring that the selected node is a descendant of the node reachable by the supplied absolute path |
class |
DescendantNodeJoinCondition
A join condition that evaluates to true only when the named node is a descendant of another named node. |
class |
DynamicOperand
A dynamic operand used in a Comparison constraint. |
class |
EquiJoinCondition
A join condition that tests whether a property on a node is equal to a property on another node. |
class |
FullTextSearch
A constraint that evaluates to true only when a full-text search applied to the search scope results in positive findings. |
class |
FullTextSearchScore
A dynamic operand that evaluates to the full-text search score of a node given by a selector, used in a Comparison
constraint and Ordering s. |
class |

NodeLocalName
A dynamic operand that evaluates to the local name of a node given by a selector, used in a Comparison constraint. |
class |
NodeName
A dynamic operand that evaluates to the qualified name of a node given by a selector, used in a Comparison constraint. |
class |
NodePath
A dynamic operand that evaluates to the path of a node given by a selector, used in a Comparison constraint. |
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 |
Ordering
A specification of the ordering for the results. |
class |
PropertyExistence
A constraint that evaluates to true only when a named property exists on a node. |
class |
PropertyValue
A dynamic operand that evaluates to the value(s) of a property on a selector, used in a Comparison constraint. |
class |

|
class |
QueryCommand
Represents the abstract base class for all query commands. |
class |
SameNode
A constraint requiring that the selected node is reachable by the supplied absolute path |
class |
SameNodeJoinCondition
A join condition that tests whether two nodes are the same nodes (that is, have the same identifier or have the same relative path from the nearest ancestor with an identifiers). |
class |
Selector
|
class |
SetCriteria
A constraint that evaluates to true when the defined operation evaluates to true. |
class |
SetQuery
This object acts as a Set operator on multiple queries , such as performing UNION, INTERSECT, and EXCEPT
operations. |
class |
