IDataAccessAdapterFetchEntityCollection Method (IEntityCollection2, IRelationPredicateBucket, Int32, ISortExpression, IPrefetchPath2, Int32, Int32)

Fetches one or more entities which match the filter information in the filterBucket into the EntityCollection passed. The entity collection object has to contain an entity factory object which will be the factory for the entity instances to be fetched. It will apply paging and it will from there use a prefetch path fetch using the read page. It's important that pageSize is smaller than the set ParameterisedPrefetchPathThreshold. It will work, though if pagesize is larger than the limits set for the ParameterisedPrefetchPathThreshold value, the query is likely to be slower than expected.
