Method Detail

setReferencePosition

public void setReferencePosition(TObjectName referenceObject)

Records the span of the object name this relation was built from, so the serialized source can point at the reference site (the ON/WHERE operand) instead of the shared column model's definition site. Ignores synthesized object names, which have no real source token (their tokens sit at line 1, column 1).
