public static void closeConnection()

add

public void add(Statement statement)

Description copied from interface: Connection

Adds the given statement to execute within this Connection. This method can be called multiple times with different statements before calling flush(), commit() or rollback().

Parameters:

statement - A statement that should be added to this Connection.

getStatements

public java.util.List<Statement> getStatements()

A list of statements scheduled to be executed.

getExpiry

public java.time.OffsetDateTime getExpiry()

Description copied from interface: Connection

flush

public void flush()

Description copied from interface: Connection

Flushes the Statements currently held by this Connection to Neo4J. Once this method is called any statements issued before a call to this method will have their results available. Note that any reads in this Connection will still only be READ COMMITTED. Writes in this Connection will be UNCOMMITTED until commit() is called. That is this Connection will be fully isolated until commit() is called. Calling Rollback will not roll back statements to this point (like a savepoint) rather it will rollback the entire Connection including any flush()s called previously.

Specified by:

flush in interface Connection

public void commit()

Description copied from interface: Connection
