public abstract class AbstractSingleFieldType

extends AbstractCustomFieldType

A abstract class that simplifies creating a CustomField that stores a single values via ofbiz. Possible values to store are:

• Short text (< 255 chars) FIELD_TYPE_STRING
• Long text (unlimited) FIELD_TYPE_TEXT
• Floating point values FIELD_TYPE_NUMBER
• Date values FIELD_TYPE_DATE

A custom field value has 3 states that it can be represented as.

In Memory Object

This is used as the primary version of the custom field value. This is what is passed to the view layer. An example would be a User or a GenericValue representing a project.

String representation

When editing a custom field value, it needs to be send to the web browser and received in text format. The in Memory Object mentioned above must have a text representation of itself, and be able to parse it. This is the value passed to the edit template. An example would be a username, or project id.

Database representation (required if storing in a database)

A custom field can be stored in a database, and there needs to be a way of getting from the object value to the database value. An example of this would be the project id.

Method Detail

getValueFromIssue

public java.lang.Object getValueFromIssue(CustomField field,
                                          org.ofbiz.core.entity.GenericValue issue)

Description copied from interface: CustomFieldType

Retrieves the Object representing the current CustomField value for the given issue. See CustomFieldType.getValueFromCustomFieldParams(com.atlassian.jira.issue.customfields.view.CustomFieldParams) for more detailed notes.

Parameters:

field - Custom field for which to retrieve the value

issue - Issue from which to retrieve the value

Returns:

Transport Object matching the Object parameter of CustomFieldType.createValue(com.atlassian.jira.issue.fields.CustomField, org.ofbiz.core.entity.GenericValue, java.lang.Object), CustomFieldType.updateValue(com.atlassian.jira.issue.fields.CustomField, org.ofbiz.core.entity.GenericValue, java.lang.Object)

See Also:

CustomFieldType.getValueFromCustomFieldParams(com.atlassian.jira.issue.customfields.view.CustomFieldParams)

remove

public java.util.Set remove(CustomField field)

called when removing a field. return issue IDs affected.

Subclasses should override this if they have specific cleanup that they need to do (such as removing select list values)

Parameters:

field - The custom field that is being removed, so any data stored for any issues for that field can be deleted.

Returns:

Set of issue ids that has been affected

createValue

public void createValue(CustomField field,
                        org.ofbiz.core.entity.GenericValue issue,
                        java.lang.Object value)

at this point we know that the value doesn't exist, and that is not null.

updateValue

public void updateValue(CustomField customField,
                        org.ofbiz.core.entity.GenericValue issue,
                        java.lang.Object value)

the value does exist, and the new value is different than the existing one.

setDefaultValue

public void setDefaultValue(CustomField field,
                            java.lang.Object value)

Description copied from interface: CustomFieldType

Sets the default value for a Custom Field

Parameters:

field - CustomField for which the default is being stored

value - Transport Object representing the value instance of the CustomField

getDefaultValue

public java.lang.Object getDefaultValue(CustomField field)

Description copied from interface: CustomFieldType
