Expression

@POJOBoilerplate
class Expression(val id: Option[String], val name: Option[Id], val language: EXPRESSION_LANGUAGE, val extension: LitSeq[Extension], val reference: Option[UriStr], val expression: Option[String], val description: Option[String], val primitiveAttributes: TreeMap[FHIRComponentFieldMeta[_], PrimitiveElementInfo]) extends Element

Base StructureDefinition for Expression Type: A expression that is evaluated in a specified context and returns a value. The context of use of the expression must specify the context in which the expression is evaluated, and how the result of the expression is used.

Subclass of core.model.Element (Base StructureDefinition for Element Type: Base definition for all elements in a resource.)

Value Params
description
  • A brief, natural language description of the condition that effectively communicates the intended semantics.
expression
  • An expression in the specified language that returns a value.
extension
  • May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
id
  • Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
language
  • The media type of the language for the expression.
name
  • A short name assigned to the expression to allow for multiple reuse of the expression in the context where it is defined.
reference
  • A URI that defines where the expression is found.
Constructor

Introduces the fields name, language, reference, expression, description.

Slower than nodalMap, but should work with subtypes (e.g. PositiveInt). If you must use it, then:

  • T should not be a Choice[_], a LitSeq[_] or an Option[_]
  • It may require a type parameter sometimes (e.g. sampleResource >>[BUNDLE_TYPE] { (_: BUNDLE_TYPE) => BUNDLE_TYPE.SEARCHSET } )

  • T should not be a Choice[_], a LitSeq[_], an Option[_], or any 'subtyped' type (eg PositiveInt). You should ensure, if T is a supertype of multiple valid choice values (e.g. T =:= Object), that the return value of fn retains the same type as the input value.
