fhir_bundle_list: Create fhir_bundle_list object

In POLAR-fhiR/fhircrackr: Handling HL7 FHIR® Resources in R

Create fhir_bundle_list object

Description

A fhir_bundle_list is a list of fhir_bundle_xml or fhir_bundle_serialized objects. It is usually returned by a call to fhir_search().

Usage

fhir_bundle_list(bundles)

Arguments

bundles

A list of xml_nodes/fhir_bundle_xml objects or of raw/fhir_bundle_serialized objects

Details

The only scenario where one would use this constructor function is when several fhir_bundle or fhir_bundle_list objects should be merged into one big fhir_bundle_list before cracking (see examples).

Examples

#unserialize example bundles
bundles1 <- fhir_unserialize(example_bundles1)
bundles2 <- fhir_unserialize(example_bundles2)

#bind them together in one fhir_bundle_list
bound_bundles <- fhir_bundle_list(c(bundles1, bundles2))
class(bound_bundles)

#bound list contains bundles from both original lists
length(bundles1)
length(bundles2)
length(bound_bundles)



#Create fhir_bundle list from xml objects
b1 <- xml2::read_xml("<Bundle><Resource><item value='1'/></Resource></Bundle>")
b2 <- xml2::read_xml("<Bundle><Resource><item value='2'/></Resource></Bundle>")

fhir_bundle_list(bundles = list(b1, b2))
fhir_bundle_list(bundles = list(fhir_bundle_xml(b1), fhir_bundle_xml(b2)))

r1 <- xml2::xml_serialize(object = b1, connection= NULL)
r2 <- xml2::xml_serialize(object = b2, connection= NULL)

fhir_bundle_list(bundles = list(r1, r2))
