Abstract Value Members

  1. abstract def allowsNull: Boolean

    Whether Java nulls are allowed to be directly set as object properties.

    Whether Java nulls are allowed to be directly set as object properties. This is desired for compatibility with Java classes, but in Scala, we have Option, therefore we need to fail fast if one wants to assign a Cassandra null value to a non-optional property.

  2. abstract def constructor: Seq[ColumnRef]

    A sequence of column references associated with parameters of the main constructor.

    A sequence of column references associated with parameters of the main constructor. If the class contains multiple constructors, the main constructor is assumed to be the one with the highest number of parameters. Multiple constructors with the same number of parameters are not allowed.

  3. abstract def setters: Map[String, ColumnRef]

    Maps a setter method name to a column reference
