Method Detail

expand

public static ValueSet expand(ValueSet valueSet)

Expand the given value set per the algorithm here: http://hl7.org/fhir/valueset.html#expansion

Parameters:

valueSet - the value set to be expanded

Returns:

the expanded value set, or the original value set if already expanded or unable to expand

getCodeSetMap

public static java.util.Map<java.lang.String,java.util.Set<java.lang.String>> getCodeSetMap(ValueSet valueSet)

Get the code set map for the given value set.

Parameters:

valueSet - the value set

Returns:

the code set map for the given value set, or an empty map if no such code set map exists

clearCache

public static void clearCache(ValueSet valueSet)

Clear the code set map cache for the given value set.

Parameters:

valueSet - the value set

getContains

public static java.util.List<ValueSet.Expansion.Contains> getContains(ValueSet.Expansion expansion)

Get a list containing ValueSet.Expansion.Contains instances where all structural hierarchies have been flattened.

Parameters:

expansion - the expansion containing the list of Contains instances to flatten

Returns:

flattened list of Contains instances for the given expansion

getValueSet

public static ValueSet getValueSet(java.lang.String url)

Get the value set associated with the given url from the FHIR registry.

Parameters:

url - the url of the value set (with optional version postfix and optional fragment id for contained resources)

Returns:

the value set associated with the given input parameter, or null if no such value set exists

isExpandable

public static boolean isExpandable(ValueSet valueSet)

isExpanded

public static boolean isExpanded(ValueSet valueSet)

validateCode

                                   Code code)

validateCode

public static boolean validateCode(ValueSet valueSet,
                                   Coding coding)
