getDefaultValue

@Nullable
V getDefaultValue(Issue issue)

The value that should be set on the issue if the field is not shown for some reason.

For example: The user does not have permission to see the field, or the field is not part of the create screen.

Parameters:

issue - the Issue.

Returns:

The default value. It can be null, or an empty collection.

createValue

void createValue(Issue issue,
                 V value)

Create the value of the issue in the data store.

Parameters:

issue - Issue this field is part of

value - Value to store in this field (eg. Collection for Version fields). Cannot be null.

updateValue

void updateValue(FieldLayoutItem fieldLayoutItem,
                 Issue issue,
                 ModifiedValue modifiedValue,
                 IssueChangeHolder issueChangeHolder)

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.

Parameters:

fieldLayoutItem - for this field within this context

issue - Issue this field is part of

modifiedValue - new value to set field to. Cannot be null.

issueChangeHolder - an object to record any changes made to the issue by this method.

updateIssue

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

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

Parameters:

fieldLayoutItem - FieldLayoutItem

issue - MutableIssue

fieldValueHolder - Field Value Holder Map

See Also:

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

void removeValueFromIssueObject(MutableIssue issue)

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.

Parameters:

issue - The issue object to be effected.

See Also:

canRemoveValueFromIssueObject(com.atlassian.jira.issue.Issue), 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

boolean canRemoveValueFromIssueObject(Issue issue)

Returns true if a call to 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.

Parameters:

issue - The Issue object.

Returns:

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

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

needsMove

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

Used to determine if the field needs input from user to be moved to the new project and/or issue type. This method is called only if the field is visible in the target project/issue type.

Parameters:

originalIssues - Collection of original Issues.

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

targetFieldLayoutItem - FieldLayoutItem

Returns:

A MessagedResult with result=true if the field needs input to be moved.

populateForMove

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

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. 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.

Parameters:

fieldValuesHolder - Map of field Values.

originalIssue - orignal Issue

targetIssue - target Issue

hasValue

boolean hasValue(Issue issue)

Determines if the field has a value for the given issue.

Parameters:

issue - the Issue.

Returns:

true if the given Issue has a value for this field.

availableForBulkEdit

String availableForBulkEdit(BulkEditBean bulkEditBean)

Determines whether the field is available for bulk editing given the BulkEditBean.

Parameters:

bulkEditBean - holds the state of the bulk-edit wizard (e.g. the selected issues for bulk editing)

Returns:

null if the field is available for bulk-editing or an i18n key of the error message to show as why the field is not available.

getValueFromParams

V getValueFromParams(Map params)
              throws FieldValidationException

Get a field value from the map of parameters passed. The params map may contain other parameters that are not relevant to this custom field.

Parameters:

params - the map of parameters.

Returns:

Value for this field from the map of parameters.

Throws:

FieldValidationException - if there is a problem with Field Validation.

populateParamsFromString

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

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.

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
