Constructor Detail

Connection

protected Connection(Properties properties,
                     String url,
                     int defaultHoldability)

Default constructor with properties.

public static boolean hasDebug(Properties properties)

getUserName

public String getUserName()

Get the user of this connection.

Returns:

String

Get the flattening sample rows (-1 if no flattening).

Returns:

int

checkClosed

protected void checkClosed()
                    throws SQLException

Check if this connection is closed or not. If it's closed, then we throw a SQLException, otherwise we do nothing.

Throws:

SQLException

checkAutoCommit

protected void checkAutoCommit()
                        throws SQLException

Method to check if we are into autocommit mode. If we do, then it throw an exception. This method is for using into commit and rollback method.

Throws:

SQLException

checkReadOnly

protected void checkReadOnly(String query)
                      throws SQLException

Check if can execute the query into the current mode (ie. readonly or not). If we can't an SQLException is throw.

Parameters:

query - Cypher query

Throws:

SQLException

checkHoldabilityParams

protected void checkHoldabilityParams(int resultSetHoldability)
                               throws SQLException

Check if the holdability parameter is conform to specification. If it doesn't, we throw an exception. Connection.setHoldability(int)

Parameters:

resultSetHoldability - The holdability value to check

Throws:

SQLException

checkConcurrencyParams

protected void checkConcurrencyParams(int resultSetConcurrency)
                               throws SQLException

Check if the concurrency parameter is conform to specification. If it doesn't, we throw an exception.

Parameters:

resultSetConcurrency - The concurrency value to check

Throws:

SQLException

checkTypeParams

protected void checkTypeParams(int resultSetType)
                        throws SQLException

Check if the resultset type parameter is conform to specification. If it doesn't, we throw an exception.
