Type Parameters:

KeyType - Type of the key object for the map being queried

ValueType - Type of the value object for the map being queried

AttributeType - Type of the attribute referenced by the attribute path

MatchType - Type of the object being compared to

public interface ContinuousQueryFilter<KeyType,ValueType,AttributeType,MatchType>
extends Serializable

An interface which provides an abstraction to check if an object matches the criteria defined in a filter. Filters are invoked within the eXtreme Scale containers hosting partitions for the map on which the query is defined. All implementations must extend AbstractCQFilter.
