9.  case class GetClassFromContained(targetObject: Expression, containedClass: Class[_]) extends Expression with NonSQLExpression with Product with Serializable

   An Expression extracting an object having the given class definition from a List of FHIR Resources.

10.  case class GetHapiValue(value: Expression, dataType: DataType, hasMethod: String, getMethod: String) extends Expression with NonSQLExpression with Product with Serializable

    Gets value of an element of a HAPI object.

    Gets value of an element of a HAPI object. This is could be composed from If and Invoke expression but having it as a dedicated expression makes the serializer expression more readable and also avoids the problems with 'If' optimisations.

    value

    the expression with the reference to the HAPI object

    dataType

    the data type of the element to get

    hasMethod

    the name of method to check if the element is present, e.g. hasNameElement()

    getMethod

    the name of method to get the value of the element, e.g. getNameElement()

    returns

    the value of the element or null if the element is not present or the object is null

11.  case class InstanceOf(value: Expression, checkedType: Class[_]) extends Expression with NonSQLExpression with Product with Serializable

    Determines if the given value is an instanceof a given class

    Determines if the given value is an instanceof a given class

    value

    the value to check

    checkedType

    the class to check the value against

12.  case class ObjectCast(value: Expression, resultType: DataType) extends Expression with NonSQLExpression with Product with Serializable

    Casts the result of an expression to another type.

    Casts the result of an expression to another type.

    value

    The value to cast

    resultType

    The type to which the value should be cast

13.  case class RegisterFid(targetObject: Expression, fidValue: Expression) extends Expression with NonSQLExpression with Product with Serializable

    Registers the mapping of a deserialized object to its _fid value.

    Registers the mapping of a deserialized object to its _fid value. The mapping is saved in '_fid_mapping' immutable state variable. Evaluates as identity.

    targetObject

    the expression, which value should be registered.

    fidValue

    the fid value to use.
