public virtual bool FetchEntity(

	IPrefetchPath2 prefetchPath,
	Context contextToUse,
	ExcludeIncludeFieldsList excludedIncludedFields
)

Parameters

entityToFetch
Type: SD.LLBLGen.Pro.ORMSupportClassesIEntity2
The entity object in which the fetched entity data will be stored. The primary key fields have to have a value.
prefetchPath
Type: SD.LLBLGen.Pro.ORMSupportClassesIPrefetchPath2
The prefetch path to use for this fetch, which will fetch all related entities defined by the path as well.
contextToUse
Type: SD.LLBLGen.Pro.ORMSupportClassesContext
The context to add the entity to if the fetch was succesful, and before the prefetch path is fetched. This ensures that the prefetch path is fetched using the context specified and will re-use already loaded entity objects.
excludedIncludedFields
Type: SD.LLBLGen.Pro.ORMSupportClassesExcludeIncludeFieldsList
The list of IEntityField2 objects which have to be excluded or included for the fetch. If null or empty, all fields are fetched (default). If an instance of ExcludeIncludeFieldsList is passed in and its ExcludeContainedFields property is set to false, the fields contained in excludedIncludedFields are kept in the query, the rest of the fields in the query are excluded.

Return Value

Type: Boolean
true if the Fetch was succesful, false otherwise
