Examples of TwigQueryNode

org.sindice.siren.qparser.json.nodes.TwigQueryNode
This query node represents a twig query that holds a root query's node boolean expression and a list of elements which can be either a {@link ChildQueryNode} or a {@link DescendantQueryNode}.
org.sindice.siren.qparser.keyword.nodes.TwigQueryNode
A {@link TwigQueryNode} represents a structured query, i.e., a {@link TwigQuery}.
It is composed of two nodes, a root and of a direct child.
A node with multiple children can be built by passing an {@link ArrayQueryNode} to the {@link #setChild(QueryNode)}.
A complex twig can be built by chaining multiple {@link TwigQueryNode}.
