case class RetractMolecule(txMeta: MoleculeBase) extends Product with Serializable

Wrapper to add retract methods on entity with transaction meta data.

RetractMolecule is created from calling Tx:

val benId = Person.name("Ben").Tx(MyMetaData.action("add member")).save.eid

// Retract entity with tx meta data
benId.Tx(MyMetaData.action("moved away")).retract

// Query for Ben's history and why he was retracted
Person(benId).name.t.op.Tx(MyMetaData.action).getHistory === List(
  ("Ben", 1028, true, "add member"), // Ben added as member
  ("Ben", 1030, false, "moved away") // Ben retracted since he moved away
)
txMeta

A molecule with transaction meta data to be saved with entity retraction
