Method Detail

getThisNodesAddress

protected String getThisNodesAddress()

processEntryEventFilter

protected boolean processEntryEventFilter(EventFilter filter,
                                          Data dataKey)

Evaluates filters of EntryEventFilter type.

Parameters:

filter - the filter which must be a EntryEventFilter

dataKey - the event entry key

Returns:

true if the filter matches

evaluateQueryEventFilter

protected boolean evaluateQueryEventFilter(EventFilter filter,
                                           Data dataKey,
                                           Object testValue,
                                           String mapNameOrNull)

Evalues the filter using a CachedQueryEntry together with the value Extractors configured for this map. The filter must be of QueryEventFilter type.

Parameters:

filter - a QueryEventFilter filter

dataKey - the entry key

testValue - the value used to evaluate the filter

mapNameOrNull - the map name. May be null if this is not a map event (e.g. cache event)

Returns:

true if the entry matches the query event filter
