Method Details

getBatchSize

public Integer getBatchSize()

Description copied from class: ChangeLogConsumerBase

override the batch size configured in config file

Overrides:

getBatchSize in class ChangeLogConsumerBase

Returns:

callAtLeastOnce

public boolean callAtLeastOnce()

some change log consumers might want to be called even if nothing happened in change log e.g. check messages in provisioners

Overrides:

callAtLeastOnce in class ChangeLogConsumerBase

Returns:

main

public static void main(String[] args)

Parameters:

args -

logIntegerIfNotZero

public static void logIntegerIfNotZero(Map<String,Object> debugMap,
 String label,
 Integer theInt)

add something to the log if its not zero (so we dont have noise). Note, if it existed previously, then remove it

Parameters:

debugMap -

label -

theInt -

logObjectIfNotNull

public static void logObjectIfNotNull(Map<String,Object> debugMap,
 String label,
 Object theObject)

add something to the log if its not null (so we dont have noise). Note, if it existed previously, then remove it

Parameters:

debugMap -

label -

theInt -

isDebugConsumer

public boolean isDebugConsumer()

Returns:

getDebugMapOverall

public Map<String,Object> getDebugMapOverall()

getChangeLogProcessorMetadata

public ChangeLogProcessorMetadata getChangeLogProcessorMetadata()

Returns:

metadata

setChangeLogProcessorMetadata

public void setChangeLogProcessorMetadata(ChangeLogProcessorMetadata changeLogProcessorMetadata1)

Parameters:

changeLogProcessorMetadata1 -

processChangeLogEntries

public long processChangeLogEntries(List<ChangeLogEntry> changeLogEntryList,
 ChangeLogProcessorMetadata changeLogProcessorMetadata1)

Description copied from class: ChangeLogConsumerBase

process the change logs

Specified by:

processChangeLogEntries in class ChangeLogConsumerBase

Parameters:

changeLogEntryList - NOTE, DO NOT CHANGE OR EDIT THE OBJECTS IN THIS LIST, THEY MIGHT BE SHARED!

Returns:

which sequence number it got up to (which sequence number was the last one processed). or -1 if none processed

• ChangeLogConsumerBase.processChangeLogEntries(List, ChangeLogProcessorMetadata)

initEsbPublisherBase

public void initEsbPublisherBase()

getEsbPublisherBase

public EsbListenerBase getEsbPublisherBase()

matchesFilter

public static boolean matchesFilter(EsbEvent esbEvent,
 String filterString)

see if the esb event matches an EL filter. Note the available objects are event for the EsbEvent, and grouperUtil for the GrouperUtil class which has a lot of utility methods

Parameters:

filterString -

esbEvent -

Returns:

true if matches, false if doesnt
