    Range of transactions (using Datomic's Log.txRange API)

    Range of transactions (using Datomic's Log.txRange API)

    Returns transactions between transaction points in time from (inclusive) and until (exclusive).

    Option args can be

    - Transaction point in time (t) of type Long/Int - Transaction entity id (tx) of type Long - Transaction wall clock time (txInstant) of type java.util.Date

    If from is None, transactions from beginning are fetched.
    If until is None, transaction until end are fetched.

    Molecule doesn't allow both arguments to be None since it would return the whole database. (Use Datomic raw access if that is needed)

    from

    First tx (inclusive). Beginning if None

    until

    Last tx (exclusive). End if None

    returns

    Log builder object to add generic datom attributes

  6. def apply(eids: expression.AttrExpressions.?): AnyRef

    Add entity id(s) input placeholder to the molecule.

    Add entity id(s) input placeholder to the molecule.
