#include <coherence/util/filter/PriorityFilter.hpp>
Inherits AbstractPriorityTask.
For example, let's assume that there is a cache that belongs to a partitioned cache service configured with a request-timeout and task-timeout of 5 seconds. Also assume that we are willing to wait longer for a particular rarely executed parallel query that does not employ any indexes. Then we could override the default timeout values by using the PriorityFilter as follows:
EqualsFilter::Handle hFilterStandard = LikeFilter::create("getComments", "%fail%");
PriorityFilter::Handle hFilterPriority = PriorityFilter::create(hFilterStandard);
hFilterPriority->setExecutionTimeoutMillis(PriorityTask::timeout_none);
hFilterPriority->setRequestTimeoutMillis(PriorityTask::timeout_none);
Set::View vSetEntries = hCache->entrySet(hFilterPriority);
This is an advanced feature which should be used judiciously.
