Expression

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. If the element is present, it must have a value for at least one of the defined elements, an @id referenced from the Narrative, or extensions

type Expression implements Element {
  description: String
  name: String
  language: String
  expression: String
  reference: Uri
  extension: [Extension]
  id: String
}

Fields​

Expression.description ● String scalar​

A brief, natural language description of the condition that effectively communicates the intended semantics.

Expression.name ● String scalar​

A short name assigned to the expression to allow for multiple reuse of the expression in the context where it is defined.

Expression.language ● String scalar​

The media type of the language for the expression.

Expression.expression ● String scalar​

An expression in the specified language that returns a value.

Expression.reference ● Uri scalar​

A URI that defines where the expression is found.

Expression.extension ● [Extension] list object​

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.

Expression.id ● String scalar​

Interfaces​

Element interface​

Base definition for all elements in a resource. If the element is present, it must have a value for at least one of the defined elements, an @id referenced from the Narrative, or extensions
