Getting Started In One Minute Guide

From NeoWiki

This is a compressed summary of the slightly more verbose Getting Started Guide. Please refer to it if something here is unclear.

• If you don't use Maven: Download the Neo release and add the Neo and JTA jars to your classpath.
• If you do use Maven: Check the Maven2 info here and add it to your pom.xml.
• Declare your relationship types and start Neo (the complete code is here: One Minute Guide Complete Code):

public enum MyRelationshipTypes implements RelationshipType
{
    KNOWS
}
...
NeoService neo = new EmbeddedNeo( "var/base" ); 

• Create a small node space:

Node firstNode = neo.createNode();
Node secondNode = neo.createNode();
Relationship relationship = firstNode.createRelationshipTo( secondNode, MyRelationshipTypes.KNOWS );

firstNode.setProperty( "message", "Hello, " );
secondNode.setProperty( "message", "world!" );
relationship.setProperty( "message", "brave Neo " );

• Recall that Neo is fully transactional, so wrap everything in transactions:

Transaction tx = Transaction.begin();
try
{
   // all Neo operations that work with the node space, for example:
   // Node firstNode = neo.createNode();
   // ... etc ...
   tx.success();
}
finally
{
   tx.finish();
   neo.shutdown();
}

• Print the result and you're done:

System.out.print( firstNode.getProperty( "message" ) );
System.out.print( relationship.getProperty( "message" ) );
System.out.print( secondNode.getProperty( "message" ) );
