Class FHIRPersistenceEvent

  • public class FHIRPersistenceEvent
extends Object
    This class represents an event fired by the FHIR persistence interceptor framework.

    • Field Detail

      • PROPNAME_PERSISTENCE_IMPL

        public static final String PROPNAME_PERSISTENCE_IMPL
        This property is of type FHIRPersistence and is the handle to the persistence layer implementation being used by the FHIR Server while processing the current request. Persistence interceptors can use this handle to invoke persistence operations.

      • PROPNAME_RESOURCE_LOCATION_URI

        public static final String PROPNAME_RESOURCE_LOCATION_URI
        This property is of type String and contains the location URI that can be used to retrieve the resource via a GET request.

        Constant Field Values

      • PROPNAME_RESOURCE_TYPE

        public static final String PROPNAME_RESOURCE_TYPE
        This property is of type String and contains the resource type associated with a create, update, read, vread, history, search, or delete operation. For other operations, this property will be null.
        See Also:
        Constant Field Values

      • PROPNAME_RESOURCE_ID

        public static final String PROPNAME_RESOURCE_ID
        This property is of type String and contains the resource id associated with an update, read, vread, history, or delete operation. For update and delete it may be null (i.e. for conditional updates/deletes) For other operations, this property will be null.

    • Constructor Detail

      • FHIRPersistenceEvent

        public FHIRPersistenceEvent()
        Default ctor.

      • FHIRPersistenceEvent

        public FHIRPersistenceEvent​(Resource fhirResource,
                            Map<String,​Object> properties)
        Ctor which accepts the FHIR resource and a collection of properties.
        Parameters:
        fhirResource - the FHIR resource associated with the event
        properties - the set of properties associated with the event.

    • Method Detail

      • getFhirResource

        public Resource getFhirResource()
        Returns the resource associated with the REST API request that triggered the interceptor invocation. This will be non-null before and after a create or update operation, and will be non-null after a read, vread, history or search operation.

      • setFhirResource

        public void setFhirResource​(Resource resource)
        Sets the specific resource in 'this'. Interceptor implementations should *not* call this method. This method is reserved for use by the FHIR Server.

      • getPrevFhirResource

        public Resource getPrevFhirResource()
        Returns the "previous" resource associated with the REST API request that triggered the interceptor invocation. This field is set only for an "update" operation and represents the existing version of the resource prior to the new resource being stored.

      • setPrevFhirResource

        public void setPrevFhirResource​(Resource prevFhirResource)
        Sets the "previous" resource associated with an "update" request.
        Parameters:
        prevFhirResource - the existing most recent version of the resource prior to the update operation being processed.

      • isPrevFhirResourceSet

        public boolean isPrevFhirResourceSet()
        This method returns true if and only if the "previous resource" field has in fact been set. This flag exists so that we can differentiate between these two scenarios:
        • The "previous resource" field is explicitly set to null.
        • The "previous resource" field is not explicitly set at all.
        Returns:
        true if the "previous resource" field is set (including the situation where it is set to null); false otherwise

      • getFhirResourceType

        public String getFhirResourceType()
        Returns the resource type associated with the FHIR REST API request that triggered the interceptor invocation. This will be non-null for a create, update, read, vread, history, search, or delete operation.

      • getFhirResourceId

        public String getFhirResourceId()
        Returns the resource id associated with the FHIR REST API request that triggered the interceptor invocation. This will be non-null for a read, vread, history, or non-conditional update/delete operation.

      • getFhirVersionId

        public String getFhirVersionId()
        Returns the version id associated with the FHIR REST API request that triggered the interceptor invocation. This will be non-null for a vread operation.

      • isStandardResourceType

        public boolean isStandardResourceType()
        Returns true if and only if the resource type value contained in the persistence event represents a standard FHIR resource type.

      • getPersistenceImpl

        public FHIRPersistence getPersistenceImpl()
        Returns the FHIRPersistence instance currently being used by the FHIR REST API layer to process the current request.

      • getProperty

        public Object getProperty​(String propertyName)
        Retrieves the named property from the set of properties available to the interceptor.
        Parameters:
        propertyName - the name of the property to retrieve.

      • getProperties

        public Map<String,​Object> getProperties()
        Retrieves the set of properties associated with the event that triggered the interceptor invocation.
