AbstractGraphDatabase

protected AbstractGraphDatabase(String storeDir)

Method Detail

createStringLogger

protected org.neo4j.kernel.impl.util.StringLogger createStringLogger()

shutdown

public final void shutdown()

Description copied from interface: GraphDatabaseService

Shuts down Neo4j. After this method has been invoked, it's invalid to invoke any methods in the Neo4j API and all references to this instance of GraphDatabaseService should be discarded.

Specified by:

shutdown in interface GraphDatabaseService

close

protected abstract void close()

getStoreDir

public final String getStoreDir()

getConfig

public abstract Config getConfig()

getMessageLog

public final org.neo4j.kernel.impl.util.StringLogger getMessageLog()

beginTx

public Transaction beginTx()

Description copied from interface: GraphDatabaseService

Starts a new transaction and associates it with the current thread.

Specified by:

beginTx in interface GraphDatabaseService

Returns:

a new transaction instance

tx

public abstract TransactionBuilder tx()

Returns a new builder where some aspects of the behavior can be configured. The transaction will ultimately begin when calling TransactionBuilder.begin().

Returns:

a builder for configuring transaction behavior and ultimately begin a transaction.

getManagementBean

@Deprecated
public final <T> T getManagementBean(Class<T> type)

Deprecated. since Neo4j may now have multiple beans implementing the same bean interface, this method has been deprecated in favor of getSingleManagementBean(Class) and getManagementBeans(Class) . Version 1.5 of Neo4j will be the last version to contain this method.

Get a single management bean. Delegates to getSingleManagementBean(Class).

getSingleManagementBean

public final <T> T getSingleManagementBean(Class<T> type)

getManagementBeans

public abstract <T> Collection<T> getManagementBeans(Class<T> type)

getKernelData

public abstract KernelData getKernelData()

isEphemeral

protected boolean isEphemeral()

toString

public String toString()

Overrides:

toString in class Object

getAllNodes

public Iterable<Node> getAllNodes()

Description copied from interface: GraphDatabaseService

Returns all nodes in the graph.

Specified by:

getAllNodes in interface GraphDatabaseService

Returns:

all nodes in the graph.

getRelationshipTypes

public Iterable<RelationshipType> getRelationshipTypes()

Description copied from interface: GraphDatabaseService

Returns all relationship types currently in the underlying store. Relationship types are added to the underlying store the first time they are used in a successfully commited 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).

Specified by:

getRelationshipTypes in interface GraphDatabaseService

Returns:

all relationship types in the underlying store
