Method Detail

getComparator

public Comparator getComparator()

Description copied from interface: LuceneFieldSorter

A comparator that can be used to order objects returned by LuceneFieldSorter.getValueFromLuceneField(String).

The Comparator must be reentrant as it could be used by Lucene from multiple threads at once.

Specified by:

getComparator in interface LuceneFieldSorter

isValidValue

public boolean isValidValue(Object value)

Description copied from interface: StatisticsMapper

Check whether this value is valid for this particular search. This is useful if you do not wish to display all the values that are indexed (eg - only show released versions)

Specified by:

isValidValue in interface StatisticsMapper

Parameters:

value - This is the same value that will be returned from LuceneFieldSorter.getValueFromLuceneField(String)

Returns:

true if this value is valid for this particular search

getValueFromLuceneField

public Object getValueFromLuceneField(String documentValue)

Description copied from interface: LuceneFieldSorter

Convert the lucene document field back to the object that you wish to use to display it.

eg. '1000' -> Version 1.

For custom fields, the return value will be passed to CustomFieldSearcherModuleDescriptor.getStatHtml(com.atlassian.jira.issue.fields.CustomField, Object, String)

Specified by:

getValueFromLuceneField in interface LuceneFieldSorter

Parameters:

documentValue - The value of the field in the lucene index

Returns:

The value that will be passed to the display

isFieldAlwaysPartOfAnIssue

public boolean isFieldAlwaysPartOfAnIssue()

Description copied from interface: StatisticsMapper

Check if the field is always part of an issues data. This should only return false in the case of a custom field where the value does not have to be set for each issue.

Specified by:

isFieldAlwaysPartOfAnIssue in interface StatisticsMapper

Returns:

true if this mapper will always be part of an issues data

getSearchUrlSuffix

@Deprecated
public SearchRequest getSearchUrlSuffix(Object value,
                                                    SearchRequest searchRequest)

Deprecated. Use #getSearchRequestAppender().appendInclusiveSingleValueClause()

Description copied from interface: StatisticsMapper

Get a suffix for the issue navigator, which allows for filtering on this value.

eg. a project field would return a SearchRequest object who's getQueryString method will produce pid=10240

Note that values returned from implementations should return values that are URLEncoded.

Specified by:

getSearchUrlSuffix in interface StatisticsMapper

Parameters:

value - This is the same value that will be returned from LuceneFieldSorter.getValueFromLuceneField(String)

searchRequest - is the search request that should be used as the base of the newly generated SearchRequest object. If this parameter is null then the return type will also be null.

Returns:

a SearchRequest object that will generate the correct issue navigator url to search the correct statistics set, null otherwise.
