Method Details

values

public static Datatype[] values()

Returns the list of Datatypes.

Returns:

the list of codes declared in the current JVM.

family

public Datatype[] family()

Returns the list of codes of the same kind as this code list element. Invoking this method is equivalent to invoking values(), except that this method can be invoked on an instance of the parent CodeList class.

Specified by:

family in interface ControlledVocabulary

Specified by:

family in class CodeList<Datatype>

Returns:

all code values for this code list.

valueOf

public static Datatype valueOf(String code)

Returns the datatype that matches the given string, or returns a new one if none match it. This methods returns the first instance (in declaration order) for which the name is equals, ignoring case, to the given name. If no existing instance is found, then a new one is created for the given name.

Parameters:

code - the name of the code to fetch or to create.

Returns:

a code matching the given name.
