Detailed Description

Provides methods to call appropriate getter/setter on an object given the property name. It does this following these rules:

  • ‪if the target object is an instance of ArrayAccess, it gets/sets the property
  • ‪if public getter/setter method exists, call it.
  • ‪if public property exists, return/set the value of it.
  • ‪else, throw exception

only to be used within Extbase, not part of TYPO3 Core API.

)
staticprivate

◆ getProperty()

static mixed TYPO3\CMS\Extbase\Reflection\ObjectAccess::getProperty ( object|array  $subject,
string  $propertyName 
)
static

Get a property of a given object. Tries to get the property the following ways:

  • ‪if the target is an array, and has this property, we call it.
  • ‪if public getter method exists, call it.
  • ‪if the target object is an instance of ArrayAccess, it gets the property on it if it exists.
  • ‪if public property exists, return the value of it.
  • ‪else, throw exception
Parameters
object | array$subject‪Object or array to get the property from
string$propertyName‪name of the property to retrieve

◆ getPropertyInternal()

static mixed TYPO3\CMS\Extbase\Reflection\ObjectAccess::getPropertyInternal ( object|array  $subject,
string  $propertyName 
)
static

Gets a property of a given object or array. This is an internal method that does only limited type checking for performance reasons. If you can't make sure that $subject is either of type array or object and $propertyName of type string you should use getProperty() instead.

getProperty()
Parameters
object | array$subject‪Object or array to get the property from
string$propertyName‪name of the property to retrieve
Exceptions

◆ getPropertyPath()

static mixed TYPO3\CMS\Extbase\Reflection\ObjectAccess::getPropertyPath ( object|array  $subject,
string  $propertyPath 
)
static

Gets a property path from a given object or array.

If propertyPath is "bla.blubb", then we first call getProperty($object, 'bla'), and on the resulting object we call getProperty(..., 'blubb')

For arrays the keys are checked likewise.

Parameters
object | array$subject‪Object or array to get the property path from
string$propertyPath
Returns
‪mixed Value of the property

  • ‪if the target object is an instance of ArrayAccess, it sets the property on it without checking if it existed.
  • ‪else, return FALSE
