Parameters
- defaultValueProvider
- Type: SD.LLBLGen.Pro.ORMSupportClassesIEntityFieldCore
The default value provider object.This object produces the value returned by ProjectEntityProperty if ValueFilter isn't set or resolves to true
for the entity passed into ProjectEntityProperty. Can't be null - projectedResultName
- Type: SystemString
Name for the projection result. Projection result consumers can use this name to further handle the projection result.
Can't be null / empty string - valueFilter
- Type: SD.LLBLGen.Pro.ORMSupportClassesIPredicate
The value filter which can be used to select between the DefaultValueProducer and the AlternativeValueProducer. If set to null,
alternativeValueProducer is ignored. - alternativeValueProducer
- Type: SD.LLBLGen.Pro.ORMSupportClassesIEntityFieldCore
The alternative value producer. Only used if ValueFilter is set to a valid filter and that filter resolves to false for the
entity passed into ProjectEntityProperty. Can't be null if valuefilter is specified - valueType
- Type: SystemType
Type of the value returned by the value producers. This can be different from the actual value produced as you can change
the type in an override of ValuePostProcess. If not set, it is set by ProjectEntityProperty to the type of the value producer selected - setUsingCTorHint
- Type: SystemBoolean
Flag which hints the projector engine how to set the destination element: via the constructor (true) or on another way
(false). This flag can be ignored by the projector engine if values can better be set otherwise.
