GetAsyncList

trait GetAsyncList[Tpl] extends AnyRef

Default asynchronous data getter methods on molecules returning Future[List[Tpl]].

For expected smaller result sets it's convenient to return Lists of tuples of data. Considered as the default getter, no postfix has been added (getAsync instead of getAsyncList).

val futureList: Future[List[(String, Int)]] = Person.name.age.getAsync
for {
  list <- futureList
} yield {
  list === List(
    ("Ben", 42),
    ("Liz", 37)
  )
}

Each asynchronous getter in this package simply wraps the result of its equivalent synchronous getter (in the get package) in a Future. getAsyncAsOf thus wraps the result of getAsOf in a Future and so on.

def getAsync(n: Int)(implicit conn: Conn): Future[List[Tpl]]
Get Future with List of n rows as tuples matching molecule.
Get Future with List of n rows as tuples matching molecule.

For more info and code examples see equivalent synchronous get method.

Since retrieving a List is considered the default fetch format, the getter method is simply named get (and not getList).
n
Int Number of rows returned
conn
Implicit Conn value in scope
returns
List[Tpl] where Tpl is a tuple of types matching the attributes of the molecule
def getAsync(implicit conn: Conn): Future[List[Tpl]]
Get Future with List of all rows as tuples matching molecule.
Get Future with List of all rows as tuples matching molecule.

For more info and code examples see equivalent synchronous get method.

def getAsyncAsOf(tx: TxReport, n: Int)(implicit conn: Conn): Future[List[Tpl]]
Get Future with List of n rows as tuples matching molecule as of tx.
Get Future with List of n rows as tuples matching molecule as of tx.

Datomic's internal asOf method can take a transaction entity id as argument to retrieve a database value as of that transaction (including).

Instead of supplying the transaction entity id, in Molecule we supply a TxReport that contains the transaction entity id (which is used as argument to Datomic internally). This is more convenient when using Molecule since we get a TxReport from transaction operations like get, update, retract etc.

For more info and code examples see equivalent synchronous getAsOf method.
tx
TxReport (returned from all molecule transaction operations)
n

def getAsyncAsOf(t: Long, n: Int)(implicit conn: Conn): Future[List[Tpl]]
Get Future with List of n rows as tuples matching molecule as of transaction time t.
Get Future with List of n rows as tuples matching molecule as of transaction time t.

Transaction time t is an auto-incremented transaction number assigned internally by Datomic.

t can for instance be retrieved in a getHistory call for an attribute and then be used to get data as of that point in time (including that transaction).

For more info and code examples see equivalent synchronous getAsOf method.
