  8. trait median extends AnyRef

    Median of attribute values.

    Median of attribute values.

    Apply median keyword to attribute to return median of attribute values of entities matching the molecule.

    Match.score.insert(1, 2, 4)
    Match.score(median).get.head === 2

    OBS: When it comes to an even number of values, Datomic has a special implementation of median that is different from the one described on the Wiki entry on the median function.

    Datomic calculates the median of even number of values as the average of the two middle numbers rounded down to nearest whole number

    Match.score.insert(1, 2, 3, 4)
    Match.score(median).get.head === 2 // (2 + 3) / 2 = 2.5 rounded down to 2

    With decimal numbers this can go wrong:

    Match.score.insert(1.0, 2.5, 2.5, 3.0)
    Match.score(median).get.head === 2 // (2.5 + 2.5) / 2 = 2.5 rounded down to 2 (This is wrong and bug report has been filed)

    Turn molecule into input molecule awaiting input.

    Apply input marker ? to attribute to turn molecule into an 'input molecule'.

    // Input molecule created at compile time.
    val ageOfPersons = m(Person.name_(?).age) // awaiting name of type String

    Debug retracting multiple entities with optional transaction meta data.

    Debug retracting multiple entities with optional transaction meta data.

    Without affecting the database, a multiple entity retract action can be debugged by adding a 'D' (for 'Debug') to the retract method.

    Here we debug a possible retraction of two comment entities with transaction meta data asserting that the retraction was done by Ben Goodman:

    debugRetract(Seq(commentEid1, commentEid2), MetaData.user("Ben Goodman"))

    This will print debugging info about the retraction to output (without affecting the database):

    // Get entity id of Ben
    val benId = Person.e.name_("Ben").get.head
    
    // Retract Ben entity directly on his entity id
    benId.retract
    id

    Deletes existing database (!) and creates a new empty db with schema from Schema Transaction file.

    Deletes existing database (!) and creates a new empty db with schema from Schema Transaction file.

    A typical development cycle in the initial stages of creating the db schema:

    1. Edit schema definition file
    2. sbt compile to update boilerplate code in generated jars
    3. Obtain a fresh connection to new empty db with updated schema:
      implicit val conn = recreateDbFrom(YourDomainSchema)
    schema

    Auto-generated YourDomainSchema Transaction object
    (in package yourdomain.schema of generated source jar)

    identifier

    Optional String identifier to name database (default empty string creates a randomUUID)

    protocol

    Datomic protocol. Defaults to "mem" for in-memory database.

    Schema data structure is a java List of Map's of key/value pairs defining the schema.
