public final class IdType
extends UriType
implements org.hl7.fhir.instance.model.api.IPrimitiveType<String>, org.hl7.fhir.instance.model.api.IIdType

This class represents the logical identity for a resource, or as much of that identity is known. In FHIR, every resource must have a "logical ID" which is defined by the FHIR specification as:

Any combination of upper or lower case ASCII letters ('A'..'Z', and 'a'..'z', numerals ('0'..'9'), '-' and '.', with a length limit of 64 characters. (This might be an integer, an un-prefixed OID, UUID or any other identifier pattern that meets these constraints.)

This class contains that logical ID, and can optionally also contain a relative or absolute URL representing the resource identity. For example, the following are all valid values for IdType, and all might represent the same resource:

• 123 (just a resource's ID)
• Patient/123 (a relative identity)
• http://example.com/Patient/123 (an absolute identity)
• http://example.com/Patient/123/_history/1 (an absolute identity with a version id)
• Patient/123/_history/1 (a relative identity with a version id)

Note that the 64 character limit applies only to the ID portion ("123" in the examples above).

In most situations, you only need to populate the resource's ID (e.g. 123) in resources you are constructing and the encoder will infer the rest from the context in which the object is being used. On the other hand, the parser will always try to populate the complete absolute identity on objects it creates as a convenience.

Regex for ID: [a-z0-9\-\.]{1,36}
