Examples of ca.uhn.fhir.context.FhirContext

ca.uhn.fhir.context.FhirContext
The FHIR context is the central starting point for the use of the HAPI FHIR API. It should be created once, and then used as a factory for various other types of objects (parsers, clients, etc.).
Important usage notes:
- Thread safety: This class is thread safe and may be shared between multiple processing threads.
- Performance: This class is expensive to create, as it scans every resource class it needs to parse or encode to build up an internal model of those classes. For that reason, you should try to create one FhirContext instance which remains for the life of your application and reuse that instance. Note that it will not cause problems to create multiple instances (ie. resources originating from one FhirContext may be passed to parsers originating from another) but you will incur a performance penalty if a new FhirContext is created for every message you parse/encode.
