Type	Description
IEnumerable<IFilterDescriptor>

VennSet

The root vennset item this processor is responsible for

Declaration

IVennSet VennSet { get; }

Type	Description
IVennSet

VennSetQueryableItems

The list of items that are being queried by this vennset

Declaration

IEnumerable<IVennSetQueryableItem> VennSetQueryableItems { get; }

IEnumerable<IVennSetQueryableItem>

Wrapper

The ISQLWrapper that backs this vennset and holds the automatically created sql

Declaration

ISQLWrapper Wrapper { get; }

Property Value

Type	Description
ISQLWrapper
