In order to make the solving of shortest path problems as general as
possible, the algorithms accept objects handling all relevant tasks regarding
costs of paths.

another.
Outcome of
Evaluator.evaluate(org.neo4j.graphdb.Path).An Evaluator controls what's to be returned from a traversal and also how
pruning is done.
Exposes an
Evaluator as a PathEvaluator.Common
Evaluators useful during common traversals.Instances describe single execution steps in a Cypher query execution plan
Execution plans form a tree of execution steps.
Instances describe statistics from the profiler of a particular step in the execution plan.

graph algorithms for Neo4j.
GraphDatabaseService represents a graph database and is used to create
new transactions with
GraphDatabaseService.beginTx().A group of settings that can represented in multiple instances.
A builder for entering details about an index to create.
Definition for an index.
This class is simply a progress counter of indexing population progress.
Index settings are used for fine-tuning the behaviour of schema indexes.
The index type describes the overall behaviour and performance profile of an index.
Factory for initial state of
TraversalBranches in a traversal.Branch state evaluator for an initial state.
An input position refers to a specific point in a query string.
A label is a grouping facility for
Node where all nodes having a label
are part of the same group.Represents an assigned or removed label for a node.
An acquired lock on an entity for a transaction, acquired from
Transaction.acquireWriteLock(Entity) or
Transaction.acquireReadLock(Entity) this lock
can be released manually using Lock.release().A log into which various levels of messages can be written
Used to obtain a
InternalLog for a specified contextThe procedure mode affects how the procedure will execute, and which capabilities
it requires.
This exception will be thrown when one or less entities were expected,
yet multiple were found.
This defines the name of an input argument for a procedure.

rule.A node in the graph with properties and relationships to other entities.
This exception will be thrown if a request is made to a node, relationship or
property that does not exist.
Representation for notifications found when executing a query.
Thrown when attempting to access or modify the graph outside of a transaction.
Represents a path in the graph.
A PathEvaluator controls what's to be returned from a traversal and also how
pruning is done.

Declares a method as a Procedure, meaning the method can be called from the
cypher query language.
Represents a changed property.
This exception is thrown from the
execute method

A relationship between two nodes in the graph.
A relationship type is mandatory on all relationships and is used to navigate
the graph.
