Method Detail

getVariants

public List<String> getVariants(String key,
                       String locale)

Specified by:

getVariants in interface AuthorityVariantsSupport

getMatches

public Choices getMatches(String field,
                 String text,
                 int collection,
                 int start,
                 int limit,
                 String locale)

Description copied from interface: ChoiceAuthority

Get all values from the authority that match the preferred value. Note that the offering was entered by the user and may contain mixed/incorrect case, whitespace, etc so the plugin should be careful to clean up user data before making comparisons. Value of a "Name" field will be in canonical DSpace person name format, which is "Lastname, Firstname(s)", e.g. "Smith, John Q.". Some authorities with a small set of values may simply return the whole set for any sample value, although it's a good idea to set the defaultSelected index in the Choices instance to the choice, if any, that matches the value.

Specified by:

getMatches in interface ChoiceAuthority

Parameters:

field - being matched for

text - user's value to match

collection - database ID of Collection for context (owner of Item)

start - choice at which to start, 0 is first.

limit - maximum number of choices to return, 0 for no limit.

locale - explicit localization key if available, or null

Returns:

a Choices object (never null).

getBestMatch

public Choices getBestMatch(String field,
                   String text,
                   int collection,
                   String locale)

Description copied from interface: ChoiceAuthority

Get the single "best" match (if any) of a value in the authority to the given user value. The "confidence" element of Choices is expected to be set to a meaningful value about the circumstances of this match. This call is typically used in non-interactive metadata ingest where there is no interactive agent to choose from among options.

Specified by:

getBestMatch in interface ChoiceAuthority

Parameters:

field - being matched for

text - user's value to match

collection - database ID of Collection for context (owner of Item)

locale - explicit localization key if available, or null

Returns:

a Choices object (never null) with 1 or 0 values.

getLabel

public String getLabel(String field,
              String key,
              String locale)

Description copied from interface: ChoiceAuthority

Get the canonical user-visible "label" (i.e. short descriptive text) for a key in the authority. Can be localized given the implicit or explicit locale specification. This may get called many times while populating a Web page so it should be implemented as efficiently as possible.

Specified by:

getLabel in interface ChoiceAuthority

Parameters:

field - being matched for

key - authority key known to this authority.

locale - explicit localization key if available, or null

Returns:

descriptive label - should always return something, never null.
