T
- Transport Object For a single Transport Objects this will be the same as S.
Otherwise, the transport Object currently supports Collection<S>
, Map<String,S>
or Map<String, Collection<S>>
.
N.B. Support for CustomFieldParams
as the Transport Object has been deprecated since 5.0.S
- Singular Form of the Transport object T.@PublicApi
@PublicSpi
public interface CustomFieldType<T,S>
This interface represents a particular type of CustomField
. It encapsulates all logic dealing with values
of a Custom Field, such as creation, update and removal of values, storage & retrieval of defaults and validation of
values.
A value instance of a custom field is represented as an Object
, from hereon in referred to as a
Transport Object. These may be of singular types (eg. Number
, String
) or
Multi-Dimensional (eg. Collection
of Strings, Map
of Date Objects, CustomFieldParams
of Option
). Most methods in the interface expect/returns Transfer Objects (e.g.
Persistence Methods (createValue(com.atlassian.jira.issue.fields.CustomField, com.atlassian.jira.issue.Issue, T)
, updateValue(com.atlassian.jira.issue.fields.CustomField, com.atlassian.jira.issue.Issue, T)
) and Transfer Object Getters
getValueFromIssue(com.atlassian.jira.issue.fields.CustomField, com.atlassian.jira.issue.Issue)
and getValueFromCustomFieldParams(com.atlassian.jira.issue.customfields.view.CustomFieldParams)
.
However, two special conversion methods (getSingularObjectFromString(java.lang.String)
& getStringFromSingularObject(S)
) act on the Singular Object level. Thus, even when the
Transfer Object type is a Collection of Number, getSingularObjectFromString would still return a single Number
object.
Implementing classes should clearly document the exact structure of the Transport Object in the Class javadoc header. If the Transport Object is Multi-Dimensional, the type of the Singular Object should also be specified. This is especially relevant for complex custom field types (CascadingSelectCFType for example)
