ca.uhn.fhir.rest.server.provider

Class HashMapResourceProvider<T extends org.hl7.fhir.instance.model.api.IBaseResource>

java.lang.Object

ca.uhn.fhir.rest.server.provider.HashMapResourceProvider<T>

Type Parameters:

T - The resource type to support

All Implemented Interfaces:

IResourceProvider

public class HashMapResourceProvider<T extends org.hl7.fhir.instance.model.api.IBaseResource>
extends Object
implements IResourceProvider

This class is a simple implementation of the resource provider interface that uses a HashMap to store all resources in memory.

This class currently supports the following FHIR operations:

• Create
• Update existing resource
• Update non-existing resource (e.g. create with client-supplied ID)
• Delete
• Search by resource type with no parameters
