FHIR JSon

Since Camel 2.21

The FHIR-JSON Data Format leverages HAPI-FHIR’s JSON parser to parse to/from JSON format to/from a HAPI-FHIR’s IBaseResource.

FHIR JSON Format Options

The FHIR JSon dataformat supports 13 options, which are listed below.

Name Default Java Type Description

Name	Default	Java Type	Description
fhirVersion	`R4`	`Enum`	The version of FHIR to use. Possible values are: DSTU2,DSTU2_HL7ORG,DSTU2_1,DSTU3,R4,R5. Enum values: DSTU2 DSTU2_HL7ORG DSTU2_1 DSTU3 R4 R5
prettyPrint	`false`	`Boolean`	Sets the pretty print flag, meaning that the parser will encode resources with human-readable spacing and newlines between elements instead of condensing output as much as possible.
serverBaseUrl		`String`	Sets the server’s base URL used by this parser. If a value is set, resource references will be turned into relative references if they are provided as absolute URLs but have a base matching the given base.
omitResourceId	`false`	`Boolean`	If set to true (default is false) the ID of any resources being encoded will not be included in the output. Note that this does not apply to contained resources, only to root resources. In other words, if this is set to true, contained resources will still have local IDs but the outer/containing ID will not have an ID.
encodeElementsAppliesToChildResourcesOnly	`false`	`Boolean`	If set to true (default is false), the values supplied to setEncodeElements(Set) will not be applied to the root resource (typically a Bundle), but will be applied to any sub-resources contained within it (i.e. search result resources in that bundle).
encodeElements		`Object`	If provided, specifies the elements which should be encoded, to the exclusion of all others. Valid values for this field would include: Patient - Encode patient and all its children Patient.name - Encode only the patient’s name Patient.name.family - Encode only the patient’s family name .text - Encode the text element on any resource (only the very first position may contain a wildcard) .(mandatory) - This is a special case which causes any mandatory fields (min 0) to be encoded.
dontEncodeElements		`Object`	If provided, specifies the elements which should NOT be encoded. Valid values for this field would include: Patient - Don’t encode patient and all its children Patient.name - Don’t encode the patient’s name Patient.name.family - Don’t encode the patient’s family name .text - Don’t encode the text element on any resource (only the very first position may contain a wildcard) DSTU2 note: Note that values including meta, such as Patient.meta will work for DSTU2 parsers, but values with subelements on meta such as Patient.meta.lastUpdated will only work in DSTU3 mode.
stripVersionsFromReferences	`false`	`Boolean`	If set to true (which is the default), resource references containing a version will have the version removed when the resource is encoded. This is generally good behaviour because in most situations, references from one resource to another should be to the resource by ID, not by ID and version. In some cases though, it may be desirable to preserve the version in resource links. In that case, this value should be set to false. This method provides the ability to globally disable reference encoding. If finer-grained control is needed, use setDontStripVersionsFromReferencesAtPaths(List).
overrideResourceIdWithBundleEntryFullUrl	`false`	`Boolean`	If set to true (which is the default), the Bundle.entry.fullUrl will override the Bundle.entry.resource’s resource id if the fullUrl is defined. This behavior happens when parsing the source data into a Bundle object. Set this to false if this is not the desired behavior (e.g. the client code wishes to perform additional validation checks between the fullUrl and the resource id).
summaryMode	`false`	`Boolean`	If set to true (default is false) only elements marked by the FHIR specification as being summary elements will be included.
suppressNarratives	`false`	`Boolean`	If set to true (default is false), narratives will not be included in the encoded values.
dontStripVersionsFromReferencesAtPaths		`Array`	If supplied value(s), any resource references at the specified paths will have their resource versions encoded instead of being automatically stripped during the encoding process. This setting has no effect on the parsing process. This method provides a finer-grained level of control than setStripVersionsFromReferences(String) and any paths specified by this method will be encoded even if setStripVersionsFromReferences(String) has been set to true (which is the default).
contentTypeHeader	`true`	`Boolean`	Whether the data format should set the Content-Type header with the type from the data format. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON.

fhirVersion

R4

Enum

The version of FHIR to use. Possible values are: DSTU2,DSTU2_HL7ORG,DSTU2_1,DSTU3,R4,R5.

Enum values:

DSTU2
DSTU2_HL7ORG
DSTU2_1
DSTU3
R4
R5

prettyPrint

false

Boolean

Sets the pretty print flag, meaning that the parser will encode resources with human-readable spacing and newlines between elements instead of condensing output as much as possible.

serverBaseUrl

String

Sets the server’s base URL used by this parser. If a value is set, resource references will be turned into relative references if they are provided as absolute URLs but have a base matching the given base.

omitResourceId

false

Boolean

If set to true (default is false) the ID of any resources being encoded will not be included in the output. Note that this does not apply to contained resources, only to root resources. In other words, if this is set to true, contained resources will still have local IDs but the outer/containing ID will not have an ID.

encodeElementsAppliesToChildResourcesOnly

false

Boolean

If set to true (default is false), the values supplied to setEncodeElements(Set) will not be applied to the root resource (typically a Bundle), but will be applied to any sub-resources contained within it (i.e. search result resources in that bundle).

encodeElements

Object

If provided, specifies the elements which should be encoded, to the exclusion of all others. Valid values for this field would include: Patient - Encode patient and all its children Patient.name - Encode only the patient’s name Patient.name.family - Encode only the patient’s family name .text - Encode the text element on any resource (only the very first position may contain a wildcard) .(mandatory) - This is a special case which causes any mandatory fields (min 0) to be encoded.

dontEncodeElements

Object

If provided, specifies the elements which should NOT be encoded. Valid values for this field would include: Patient - Don’t encode patient and all its children Patient.name - Don’t encode the patient’s name Patient.name.family - Don’t encode the patient’s family name .text - Don’t encode the text element on any resource (only the very first position may contain a wildcard) DSTU2 note: Note that values including meta, such as Patient.meta will work for DSTU2 parsers, but values with subelements on meta such as Patient.meta.lastUpdated will only work in DSTU3 mode.

stripVersionsFromReferences

false

Boolean

If set to true (which is the default), resource references containing a version will have the version removed when the resource is encoded. This is generally good behaviour because in most situations, references from one resource to another should be to the resource by ID, not by ID and version. In some cases though, it may be desirable to preserve the version in resource links. In that case, this value should be set to false. This method provides the ability to globally disable reference encoding. If finer-grained control is needed, use setDontStripVersionsFromReferencesAtPaths(List).

overrideResourceIdWithBundleEntryFullUrl

false

Boolean

If set to true (which is the default), the Bundle.entry.fullUrl will override the Bundle.entry.resource’s resource id if the fullUrl is defined. This behavior happens when parsing the source data into a Bundle object. Set this to false if this is not the desired behavior (e.g. the client code wishes to perform additional validation checks between the fullUrl and the resource id).

summaryMode

false

Boolean

If set to true (default is false) only elements marked by the FHIR specification as being summary elements will be included.

suppressNarratives

false

Boolean

If set to true (default is false), narratives will not be included in the encoded values.

dontStripVersionsFromReferencesAtPaths

Array

If supplied value(s), any resource references at the specified paths will have their resource versions encoded instead of being automatically stripped during the encoding process. This setting has no effect on the parsing process. This method provides a finer-grained level of control than setStripVersionsFromReferences(String) and any paths specified by this method will be encoded even if setStripVersionsFromReferences(String) has been set to true (which is the default).

contentTypeHeader

true

Boolean

Whether the data format should set the Content-Type header with the type from the data format. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON.
