Method Detail

getAllPopulatedChildElementsOfType

public <T extends IBase> List<T> getAllPopulatedChildElementsOfType(IBaseResource theResource,
                                                                    Class<T> theType)

Returns a list containing all child elements (including the resource itself) which are non-empty and are either of the exact type specified, or are a subclass of that type.

For example, specifying a type of StringDt would return all non-empty string instances within the message. Specifying a type of IResource would return the resource itself, as well as any contained resources.

Note on scope: This method will descend into any contained resources (IResource.getContained()) as well, but will not descend into linked resources (e.g. BaseResourceReferenceDt.getResource()) or embedded resources (e.g. Bundle.entry.resource)

Parameters:

theResource - The resource instance to search. Must not be null.

theType - The type to search for. Must not be null.

Returns:

Returns a list of all matching elements

getAllResourceReferences

public List<ResourceReferenceInfo> getAllResourceReferences(IBaseResource theResource)

getDefinition

public BaseRuntimeChildDefinition getDefinition(Class<? extends IBaseResource> theResourceType,
                                                String thePath)

getValues

public List<Object> getValues(IBaseResource theResource,
                              String thePath)

getValues

public <T> List<T> getValues(IBaseResource theResource,
                             String thePath,
                             Class<T> theWantedClass)

visit

public void visit(IBaseResource theResource,
                  IModelVisitor theVisitor)

Visit all elements in a given resource

Note on scope: This method will descend into any contained resources (IResource.getContained()) as well, but will not descend into linked resources (e.g. BaseResourceReferenceDt.getResource()) or embedded resources (e.g. Bundle.entry.resource)

Parameters:

theResource - The resource to visit

theVisitor - The visitor

getSingleValueOrNull

public Object getSingleValueOrNull(IBase theTarget,
                                   String thePath)

getSingleValueOrNull

public <T> T getSingleValueOrNull(IBase theTarget,
                                  String thePath,
                                  Class<T> theWantedType)

cloneInto

public void cloneInto(IBase theSource,
                      IBase theTarget,
                      boolean theIgnoreMissingFields)

Clones all values from a source object into the equivalent fields in a target object

Parameters:

theSource - The source object (must not be null)

theTarget - The target object to copy values into (must not be null)

theIgnoreMissingFields - The ignore fields in the target which do not exist (if false, an exception will be thrown if the target is unable to accept a value from the source)
