Class EvidenceVariable.Characteristic

  • All Implemented Interfaces:
    Visitable
    Enclosing class:
    EvidenceVariable

    public static class EvidenceVariable.Characteristic
    extends BackboneElement
    A characteristic that defines the members of the evidence element. Multiple characteristics are applied with "and" semantics.
    • Method Detail

      • getDescription

        public String getDescription()
        A short, natural language description of the characteristic that could be used to communicate the criteria to an end- user.
        Returns:
        An immutable object of type String that may be null.
      • getDefinition

        public Element getDefinition()
        Define members of the evidence element using Codes (such as condition, medication, or observation), Expressions ( using an expression language such as FHIRPath or CQL) or DataRequirements (such as Diabetes diagnosis onset in the last year).
        Returns:
        An immutable object of type Element that is non-null.
      • getUsageContext

        public List<UsageContext> getUsageContext()
        Use UsageContext to define the members of the population, such as Age Ranges, Genders, Settings.
        Returns:
        An unmodifiable list containing immutable objects of type UsageContext that may be empty.
      • getExclude

        public Boolean getExclude()
        When true, members with this characteristic are excluded from the element.
        Returns:
        An immutable object of type Boolean that may be null.
      • getParticipantEffective

        public Element getParticipantEffective()
        Indicates what effective period the study covers.
        Returns:
        An immutable object of type Element that may be null.
      • getTimeFromStart

        public Duration getTimeFromStart()
        Indicates duration from the participant's study entry.
        Returns:
        An immutable object of type Duration that may be null.
      • getGroupMeasure

        public GroupMeasure getGroupMeasure()
        Indicates how elements are aggregated within the study effective period.
        Returns:
        An immutable object of type GroupMeasure that may be null.
      • accept

        public void accept​(String elementName,
                           int elementIndex,
                           Visitor visitor)
        Description copied from interface: Visitable
        Accept a Visitor and invoke the appropriate visit methods. A typical implementation would look like this:
         if (visitor.preVisit(this)) {
             visitor.visitStart(elementName, elementIndex, this);
             if (visitor.visit(elementName, elementIndex, this)) {
                 // visit children
             }
             visitor.visitEnd(elementName, elementIndex, this);
             visitor.postVisit(this);
         }
         
        Specified by:
        accept in interface Visitable
        Specified by:
        accept in class AbstractVisitable
        Parameters:
        elementName - the name of the element in the context of this visit
        elementIndex - the index of the element in a list or -1 if it is not contained within a List
        visitor - the visitor to use
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class Object
