public void populateParamsFromString(Map<String,Object> fieldValuesHolder,
 String stringValue,
 Issue issue)
                              throws FieldValidationException

Description copied from interface: OrderableField

Used to convert from a user friendly string value and put the result into the fieldValuesHolder. This method is useful for places like Jelly where the field value can be a name (e.g. issue type name) and not a regular id that is used in the web pages.

Specified by:

populateParamsFromString in interface OrderableField<Object>

Parameters:

fieldValuesHolder - Map of field Values.

stringValue - user friendly string value

issue - the Issue

Throws:

FieldValidationException - if cannot convert to a value from the given string

updateIssue

public void updateIssue(FieldLayoutItem fieldLayoutItem,
 MutableIssue issue,
 Map fieldValueHolder)

Description copied from interface: OrderableField

Record the value on the issue (not saving it to the database, see updateValue).

Specified by:

updateIssue in interface OrderableField<Object>

Parameters:

fieldLayoutItem - FieldLayoutItem

issue - MutableIssue

fieldValueHolder - Field Value Holder Map

See Also:

• OrderableField.updateValue(com.atlassian.jira.issue.fields.layout.field.FieldLayoutItem, com.atlassian.jira.issue.Issue, com.atlassian.jira.issue.ModifiedValue, com.atlassian.jira.issue.util.IssueChangeHolder)

removeValueFromIssueObject

public void removeValueFromIssueObject(MutableIssue issue)

Description copied from interface: OrderableField

Removes the field value from the given MutableIssue object.

Note that this operation does not actually persist the change, it just clears the value from the given Issue object. The caller will still need to call #updateValue() in order to persist the change.

Some Fields may choose to quietly ignore this request. eg The SecurityLevel Field will not remove Security Level from subtasks because the subtask must always take the Security Level of its parent issue.

Specified by:

removeValueFromIssueObject in interface OrderableField<Object>

Parameters:

issue - The issue object to be effected.

See Also:

• OrderableField.canRemoveValueFromIssueObject(com.atlassian.jira.issue.Issue)
• OrderableField.updateValue(com.atlassian.jira.issue.fields.layout.field.FieldLayoutItem, com.atlassian.jira.issue.Issue, com.atlassian.jira.issue.ModifiedValue, com.atlassian.jira.issue.util.IssueChangeHolder)

canRemoveValueFromIssueObject

public boolean canRemoveValueFromIssueObject(Issue issue)

Description copied from interface: OrderableField

Returns true if a call to OrderableField.removeValueFromIssueObject(com.atlassian.jira.issue.MutableIssue) will actually remove the value.

There a few different reasons why this method may return false:

• The OrderableField can sometimes remove the value, but it decides that it is not relevant for this Issue. eg: Security Level will ignore remove requests on a subtask, as the subtask Security is not set explicitly (it is always inherited from its parent issue).
• It may possible to remove this value, but the OrderableField does not actually do the job, it is done through some special mechanism. eg Attachments.
• This field is some special system field which it is invalid to remove. eg Project. In these cases calling removeValueFromIssueObject() would normally raise an UnsupportedOperationException.

In general it is safe to call removeValueFromIssueObject() even if this method returns false, as the request will be silently ignored. However there are a couple of special fields where calling removeValueFromIssueObject() will throw an UnsupportedOperationException - eg if you try to remove the Project.

Specified by:

canRemoveValueFromIssueObject in interface OrderableField<Object>

Parameters:

issue - The Issue object.

Returns:

true if a call to OrderableField.removeValueFromIssueObject(com.atlassian.jira.issue.MutableIssue) will actually remove the value.

• OrderableField.removeValueFromIssueObject(com.atlassian.jira.issue.MutableIssue)

needsMove

public MessagedResult needsMove(Collection originalIssues,
 Issue targetIssue,
 FieldLayoutItem targetFieldLayoutItem)

Parameters:

originalIssues - Collection of original Issues.

targetIssue - Nonexistent issue object with values representing those of issue(s) after move

populateForMove

public void populateForMove(Map<String,Object> fieldValuesHolder,
 Issue originalIssue,
 Issue targetIssue)

Description copied from interface: OrderableField

Used to populate the fieldValueHolder with parameters for move issue screen. This field is only called if the issue needs to be updated during move, i.e. OrderableField.needsMove(java.util.Collection, com.atlassian.jira.issue.Issue, com.atlassian.jira.issue.fields.layout.field.FieldLayoutItem) returned true, and the remote user (the one performing the move) has the permission to actually update this field.

Specified by:

populateForMove in interface OrderableField<Object>

Parameters:

originalIssue - orignal Issue

targetIssue - target Issue

populateFromIssue

public void populateFromIssue(Map<String,Object> fieldValuesHolder,

 Issue issue,
 ModifiedValue modifiedValue,
 IssueChangeHolder issueChangeHolder)

Description copied from interface: OrderableField

Update the issue in the data store.

Fields that are simply stored in the JIRAISSUE DB table, need not do anything here as this table is written to one time to include all fields that changed. Fields using other DB tables must update that table with the appropriate values.

A sorter to be used when sorting columns in a table. This sort uses the Lucene Document Collection and is therefore a lot faster than sorting the issues in memory.

Specified by:

getSorter in interface NavigableField

Returns:

A sorter that can be used to sort this field, or null depending on the value of NavigableField.getSortComparatorSource()
