Class RecordDependency

For a soft link (IsSoftLink), the name of the sibling discriminator column that says which entity FieldName points at - the value of EntityIDFieldName on the payload field. Undefined for hard foreign keys.

The name of the entity that is the "parent" in the relationship

The name of the field in the related entity that is the foreign key field back to the primary key of the "parent" entity

True when this dependency is a polymorphic (soft) link rather than a hard foreign key - that is, when FieldName is the RecordID-shaped payload column of an EntityID/RecordID pair declared via EntityFieldInfo.EntityIDFieldName.

The distinction matters because the two kinds of link store the target differently: a hard foreign key holds the bare primary key value, while a polymorphic link holds the canonical CompositeKey.ToRecordID() encoding (ID|<guid>). Anything that rewrites the link - record merge, most importantly - has to write the right one, so this flag is what tells it which.

Optional, and absent/false means "hard foreign key", so callers written before polymorphic links were detected keep their existing behavior.

The value of the primary key field in the parent record. MemberJunction supports composite(multi-field) primary keys. However, foreign keys only support links to single-valued primary keys in their linked entity.

The name of the entity that is the "child" in the relationship
