Parameters

valueProjectors

Type: System.Collections.GenericListIDataValueProjector
The value projectors.

projector

Type: SD.LLBLGen.Pro.ORMSupportClassesIGeneralDataProjector
The projector to use for projecting a plain row onto a new object provided by the projector.

queryToExecute

Type: SD.LLBLGen.Pro.ORMSupportClassesIRetrievalQuery
The query to execute.

performValueProjectionsOnRawRow

Type: SystemBoolean
if set to true the projection method will perform value projections on the plain row prior to using it in the projector and will create a new object row to store the projected values in. If false, the plain row is passed on as-is

postProcessDBNullValues

Type: SystemBoolean
if set to true it will perform a DBNull to null conversion on the row passed to the projector. Only specify this to true if the projector deals with object arrays to the outside. In all other cases make the projectors already convert the DBNull values.

typeConvertersToRun

Type: System.Collections.GenericDictionaryInt32, TypeConverter
The type converters to use for the query. The key is the index in the result row, the value is the type converter to run on that value. These type converters have to run prior to the projectors will run.
