NeoService
shell
component is available on the
classpath. This method is identical to invoking
enableRemoteShell( null )
.
enableRemoteShell
in interface NeoService
true
if the shell has been enabled,
false
otherwise (false
usually indicates that
the shell
jar dependency is not on the classpath)public boolean enableRemoteShell(Map<String,Serializable> initialProperties)
NeoService
shell
component is available on the classpath. This will
publish a shell access interface on an RMI registry on localhost (with
configurable port and RMI binding name). It can be accessed by a
client that implements org.neo4j.util.shell.ShellClient
from the Neo4J shell
project. Typically, the
shell
binary package is used (see
neo4j.org/download).
The shell is parameterized by a map of properties passed in to this method. Currently, two properties are used:
port
, an Integer
describing the port of the RMI
registry where the Neo4j shell will be bound, defaults to
1337
name
, the String
under which
the Neo4j shell will be bound in the RMI registry, defaults to
shell

initialProperties
- a set of properties that will be used to
configure the remote shell, or null
if the default
properties should be used
true
if the shell has been enabled,
false
otherwise (false
usually indicates that
the shell
jar dependency is not on the classpath)public Iterable<RelationshipType> getRelationshipTypes()
NeoService
node.createRelationshipTo(...)
. Note that
this method is guaranteed to return all known relationship types, but
it does not guarantee that it won't return more than that (e.g.
it can return "historic" relationship types that no longer have any
relationships in the node space).
