Modifier and Type	Interface and Description
interface	Evaluator<T extends org.neo4j.graphdb.PropertyContainer> Tells whether objects match some criteria.

Classes in er.neo4jadaptor.query.neo4j_eval.evaluators that implement HasCost

Modifier and Type	Class and Description
class	AlwaysTrue<T extends org.neo4j.graphdb.PropertyContainer> Evaluates all objects as matching its criteria, without even checking.
class	BoolEvaluator<T extends org.neo4j.graphdb.PropertyContainer> Evaluates candidates to match some or all of some other Evaluators building something equivalent to logical sentences.
class	Comparison<T extends org.neo4j.graphdb.PropertyContainer> Checks if a some of the candidate's property/relationship value is equal/greater/less than some value.
class	Negate<T extends org.neo4j.graphdb.PropertyContainer> Positively evaluates only candidates that do NOT match some other evaluator, making it logical negation.
class	RegexMatch<T extends org.neo4j.graphdb.PropertyContainer> Tells if a value retrieved from a candidate using Retriever matches some regular expression.
