Parameters
- rootNodeParameters
- Type: SD.LLBLGen.Pro.ORMSupportClassesQueryParameters
The parameters. - forceParameterizedPPath
- Type: SystemBoolean
if set to true, it always will use a parameterized prefetch path, no matter what. Used for paging
scenario's - transactionToUse
- Type: SD.LLBLGen.Pro.ORMSupportClassesITransaction
The transaction to use. Is null in adapter scenarios - parameterisedPrefetchPathThreshold
- Type: SystemInt32
The parameterised prefetch path threshold. - fetchNodeFunc
- Type: SystemActionQueryParameters
The fetch node func, used to fetch the data for the current node. - mergeManyToManyFunc
- Type: SystemActionITransaction, IPrefetchPathElementCore, QueryParameters, IEntityCollectionCore
The merge many to many func, which is used in a m:n scenario to merge the fetched
entities into the root entities using a m:n merge which will fetch the intermediate rows to perform the merge.
