Class DataRequirement.DateFilter

  • All Implemented Interfaces:
    Visitable
    Enclosing class:
    DataRequirement
    public static class DataRequirement.DateFilter
extends BackboneElement
    Date filters specify additional constraints on the data in terms of the applicable date range for specific elements. Each date filter specifies an additional constraint on the data, i.e. date filters are AND'ed, not OR'ed.

    • Method Detail

      • getPath

        public String getPath()
        The date-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 date, dateTime, Period, Schedule, or Timing.
        Returns:
        An immutable object of type String that may be null.

      • getSearchParam

        public String getSearchParam()
        A date parameter that refers to a search parameter defined on the specified type of the DataRequirement, and which searches on elements of type date, dateTime, Period, Schedule, or Timing.
        Returns:
        An immutable object of type String that may be null.

      • getValue

        public Element getValue()
        The value of the filter. If period is specified, the filter will return only those data items that fall within the bounds determined by the Period, inclusive of the period boundaries. If dateTime is specified, the filter will return only those data items that are equal to the specified dateTime. If a Duration is specified, the filter will return only those data items that fall within Duration before now.
        Returns:
        An immutable object of type Element 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
