Expression

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 parameters:
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.

override def equals(obj: Any): Boolean

Compares the receiver object (this) with the argument object (that) for equivalence.

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

  • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
  • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

Value parameters:
that

the object to compare against this object for equality.

Returns:

true if the receiver object is equivalent to the argument; false otherwise.

override def hashCode(): Int

Calculate a hash code value for the object.

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Returns:

the hash code value for this object.
