Method Detail

createConnectionAdvice

public Object createConnectionAdvice(org.aspectj.lang.ProceedingJoinPoint proceedingJoinPoint)
                              throws Throwable

Audits the creation of relationships via createConnection(). This method only needs to be run 'after returning'. However, in Java 7 the order in which these methods are returned from Class.getDeclaredMethods (even though there is no order guaranteed) seems to differ from Java 6. SpringAOP depends on this ordering to determine advice precedence. By normalizing all advice into Around advice we can alleviate this issue.

Parameters:

connection -

Throws:

Throwable

updateConnectionAdvice

public Object updateConnectionAdvice(org.aspectj.lang.ProceedingJoinPoint proceedingJoinPoint,
                            String groupId,
                            ConnectionDTO connectionDTO,
                            ConnectionDAO connectionDAO)
                              throws Throwable

Audits the creation and removal of relationships via updateConnection().

Parameters:

proceedingJoinPoint -

connectionDTO -

connectionDAO -

Returns:

Throws:

Throwable

removeConnectionAdvice

public void removeConnectionAdvice(org.aspectj.lang.ProceedingJoinPoint proceedingJoinPoint,
                          String groupId,
                          String id,
                          ConnectionDAO connectionDAO)
                            throws Throwable

Audits the removal of relationships via deleteConnection().

Parameters:

proceedingJoinPoint -

id -

connectionDAO -

Throws:

Throwable

createConnectDetails

public ConnectDetails createConnectDetails(Connection connection,
                                  Collection<Relationship> relationships)
