    Class TriggerDefinition

    TriggerDefinition Class

    Base StructureDefinition for TriggerDefinition Type: A description of a triggering event. Triggering events can be named events, data events, or periodic, as determined by the type element.

    FHIR Specification

    • Short: Defines an expected trigger for a module
    • Definition: A description of a triggering event. Triggering events can be named events, data events, or periodic, as determined by the type element.
    • Comment: If an event is a named-event, it means the event is completely pre-coordinated, and no other information can be specified for the event. If the event is one of the data- events, the data and condition elements specify the triggering criteria. The data element specifies the structured component, and the condition element provides additional optional refinement of that structured component. If the event is periodic, the timing element defines when the event is triggered. For both data- and periodic events, a name can be provided as a shorthand for the formal semantics provided by the other elements.

    • Definition: The type of triggering event.

    TriggerDefinition.name Element

    FHIR Specification

    • Short: Name or URI that identifies the event
    • Definition: A formal name for the event. This may be an absolute URI that identifies the event formally (e.g. from a trigger registry), or a simple relative URI that identifies the event in a local context.
    • Comment: An event name can be provided for all event types, but is required for named events. If a name is provided for a type other than named events, it is considered to be a shorthand for the semantics described by the formal description of the event.

    TriggerDefinition.timing[x] Element

    @ChoiceDataTypesMeta('TriggerDefinition.timing[x]', ['Timing','Reference','date','dateTime',]

    FHIR Specification

    • Short: Timing of the event
    • Definition: The timing of the event (if this is a periodic trigger).
    • FHIR Types: 'Timing', 'Reference', 'date', 'dateTime',
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true
    data?: DataRequirement[]

    TriggerDefinition.data Element

    FHIR Specification

    • Short: Triggering data of the event (multiple = 'and')
    • Definition: The triggering data of the event (if this is a data trigger). If more than one data is requirement is specified, then all the data requirements must be true.
    • Comment: This element shall be present for any data type trigger.
    • FHIR Type: DataRequirement
    • Cardinality: 0..*
    • isModifier: false
    • isSummary: true
    condition?: Expression

    TriggerDefinition.condition Element

    FHIR Specification

    • Short: Whether the event triggers (boolean expression)
    • Definition: A boolean-valued expression that is evaluated in the context of the container of the trigger definition and returns whether or not the trigger fires.
    • Comment: This element can be only be specified for data type triggers and provides additional semantics for the trigger. The context available within the condition is based on the type of data event. For all events, the current resource will be available as context. In addition, for modification events, the previous resource will also be available. The expression may be inlined, or may be a simple absolute URI, which is a reference to a named expression within a logic library referenced by a library element or extension within the containing resource. If the expression is a FHIR Path expression, it evaluates in the context of a resource of one of the type identified in the data requirement, and may also refer to the variable %previous for delta comparisons on events of type data-changed, data-modified, and data-deleted which will always have the same type.
    • Requirements: Need to be able to formally describe the triggering criteria.
    • FHIR Type: Expression
    • Cardinality: 0..1
    • isModifier: false
    • isSummary: true

    Methods

    • Parse the provided TriggerDefinition JSON to instantiate the TriggerDefinition data model.

      Parameters

        JSON representing FHIR TriggerDefinition

      • OptionaloptSourceField: string

        Optional data source field (e.g. <complexTypeName>.<complexTypeFieldName>); defaults to TriggerDefinition

      this

      PrimitiveTypeError for invalid value

    • Returns boolean

    • Assigns the provided array of Extension values to the extension property.

      Parameters
