Oracle® Coherence .NET API Reference Release 3.7.1
E22844-03

PriorityFilter is used to explicitly control the scheduling priority and timeouts for execution of filter-based methods.

Namespace:  Tangosol.Util.Filter
Assembly:  Coherence (in Coherence.dll) Version: 3.7.1.23 (3.7.1.23)

Syntax

C#
public class PriorityFilter : AbstractPriorityTask, 
	IIndexAwareFilter, IEntryFilter, IFilter

Remarks

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:
CopyC#
LikeFilter     filterStandard = new LikeFilter("GetComments", "%fail%");
PriorityFilter filterPriority = new PriorityFilter(filterStandard);
filterPriority.ExecutionTimeoutMillis = PriorityTaskTimeout.None;
filterPriority.RequestTimeoutMillis   = PriorityTaskTimeout.None;
ICollection entries = cache.GetEntries(filterPriority);
 This is an advanced feature which should be used judiciously.
