Method Detail

createProcessorAdvice

public ProcessorNode createProcessorAdvice(org.aspectj.lang.ProceedingJoinPoint proceedingJoinPoint)
                                    throws Throwable

Audits the creation of processors via createProcessor(). 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:

processor -

Throws:

Throwable

updateProcessorAdvice

public Object updateProcessorAdvice(org.aspectj.lang.ProceedingJoinPoint proceedingJoinPoint,
                           String groupId,
                           ProcessorDTO processorDTO,
                           ProcessorDAO processorDAO)
                             throws Throwable

Audits the configuration of a single processor.

Parameters:

proceedingJoinPoint -

processorDTO -

processorDAO -

Returns:

Throws:

Throwable

removeProcessorAdvice

public void removeProcessorAdvice(org.aspectj.lang.ProceedingJoinPoint proceedingJoinPoint,
                         String groupId,
                         String processorId,
                         ProcessorDAO processorDAO)
                           throws Throwable

Audits the removal of a processor via deleteProcessor().

Parameters:

proceedingJoinPoint -

processorId -

processorDAO -

Throws:

Throwable

generateAuditRecord

public Action generateAuditRecord(ProcessorNode processor,
                         Operation operation)

Generates an audit record for the creation of a processor.

Parameters:

processor -

operation -

Returns:

public Action generateAuditRecord(ProcessorNode processor,
                         Operation operation,
                         ActionDetails actionDetails)

Generates an audit record for the creation of a processor.

Parameters:

processor -

operation -

Returns:

extractConfiguredPropertyValues

private Map<String,String> extractConfiguredPropertyValues(ProcessorNode processor,
                                                 ProcessorDTO processorDTO)

Extracts the values for the configured properties from the specified Processor.

Parameters:

processor -

processorDTO -

Returns:

locatePropertyDescriptor

private PropertyDescriptor locatePropertyDescriptor(Set<PropertyDescriptor> propertyDescriptors,
                                          PropertyDescriptor specDescriptor)

Locates the actual property descriptor for the given spec property descriptor.

Parameters:
