Class DataRequirement.CodeFilter

  • All Implemented Interfaces:
    Visitable
    Enclosing class:
    DataRequirement
    public static class DataRequirement.CodeFilter
extends BackboneElement
    Code filters specify additional constraints on the data, specifying the value set of interest for a particular element of the data. Each code filter defines an additional constraint on the data, i.e. code filters are AND'ed, not OR'ed.

    • Method Detail

      • getPath

        public String getPath()
        The code-valued attribute of the filter. The specified path SHALL be a FHIRPath resolveable on the specified type of the DataRequirement, and SHALL consist only of identifiers, constant indexers, and .resolve(). The path is allowed to contain qualifiers (.) to traverse sub-elements, as well as indexers ([x]) to traverse multiple-cardinality sub- elements (see the [Simple FHIRPath Profile](fhirpath.html#simple) for full details). Note that the index must be an integer constant. The path must resolve to an element of type code, Coding, or CodeableConcept.
        Returns:
        An immutable object of type String that may be null.

      • getSearchParam

        public String getSearchParam()
        A token parameter that refers to a search parameter defined on the specified type of the DataRequirement, and which searches on elements of type code, Coding, or CodeableConcept.
        Returns:
        An immutable object of type String that may be null.

      • getValueSet

        public Canonical getValueSet()
        The valueset for the code filter. The valueSet and code elements are additive. If valueSet is specified, the filter will return only those data items for which the value of the code-valued element specified in the path is a member of the specified valueset.
        Returns:
        An immutable object of type Canonical that may be null.

      • getCode

        public List<Coding> getCode()
        The codes for the code filter. If values are given, the filter will return only those data items for which the code- valued attribute specified by the path has a value that is one of the specified codes. If codes are specified in addition to a value set, the filter returns items matching a code in the value set or one of the specified codes.
        Returns:
        An unmodifiable list containing immutable objects of type Coding that may be empty.

      • 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
