    • 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 java.lang.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 java.lang.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, non-whole-system history, or non-conditional update/delete operation.
      • getFhirVersionId

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

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

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