Constructor Detail

VersionStatisticsMapper

public VersionStatisticsMapper(java.lang.String clauseName,
                               java.lang.String documentConstant,
                               VersionManager versionManager,
                               boolean includeArchived)
Method Detail

getComparator

public java.util.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(java.lang.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 java.lang.Object getValueFromLuceneField(java.lang.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.

This does the reverse of what IssueDocument does.

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

getSearchUrlSuffix

public SearchRequest getSearchUrlSuffix(java.lang.Object value,
                                        SearchRequest searchRequest)
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.

getClauseName

protected java.lang.String getClauseName()

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

getDocumentConstant

public java.lang.String getDocumentConstant()
Description copied from interface: LuceneFieldSorter
Get the constant that this field is indexed with.

Specified by:
