class FluentExtension extends DataExtension (View source)

Basic fluent extension

When determining whether a field is localised, the following config options are checked in order:

  • translate (uninherited, for each class in the chain)
  • field_exclude
  • field_include
  • data_exclude
  • data_include

Traits

Shared functionality between both FluentExtension and FluentFilteredExtension

Constants

SUFFIX

The table suffix that will be applied to create localisation tables

TRANSLATE_NONE

translate config key to disable localisations for this table

INHERITANCE_MODE_EXACT

Content inheritance - content will be served from the following sources in this order: current locale

INHERITANCE_MODE_FALLBACK

Content inheritance - content will be served from the following sources in this order: current locale, fallback locale

INHERITANCE_MODE_ANY

Content inheritance - content will be served from the following sources in this order: current locale, fallback locale, base record

mixed
withOwner(mixed $owner, callable $callback, array $args = [])

Temporarily modify the owner. The original owner is ensured to be restored

public
clearOwner()

Clear the current owner, and restore extension to the state prior to the last setOwner()

public
object
getOwner()

Returns the owner of this extension.

public static 
string
get_classname_without_arguments(string $extensionStr)

Helper method to strip eval'ed arguments from a string that's passed to DataObject::$extensions or Object::add_extension().
