__construct(array $objects = []) X-Ref |
The class constructor. param: DataObject[] $objects An array of DataObject objects to bind to the data set. |
__call($method, $arguments = []) X-Ref |
The magic call method is used to call object methods using the iterator. Example: $array = $objectList->foo('bar'); The object list will iterate over its objects and see if each object has a callable 'foo' method. If so, it will pass the argument list and assemble any return values. If an object does not have a callable method no return value is recorded. The keys of the objects and the result array are maintained. param: string $method The name of the method called. param: array $arguments The arguments of the method called. return: array An array of values returned by the methods called on the objects in the data set. |
__get($property) X-Ref |
The magic get method is used to get a list of properties from the objects in the data set. Example: $array = $dataSet->foo; This will return a column of the values of the 'foo' property in all the objects (or values determined by custom property setters in the individual DataObject's). The result array will contain an entry for each object in the list (compared to __call which may not). The keys of the objects and the result array are maintained. param: string $property The name of the data property. return: array An associative array of the values. |
__isset($property) X-Ref |
The magic isset method is used to check the state of an object property using the iterator. Example: $array = isset($objectList->foo); param: string $property The name of the property. return: boolean True if the property is set in any of the objects in the data set. |
__set($property, $value) X-Ref |
The magic set method is used to set an object property using the iterator. Example: $objectList->foo = 'bar'; This will set the 'foo' property to 'bar' in all of the objects (or a value determined by custom property setters in the DataObject). param: string $property The name of the property. param: mixed $value The value to give the data property. return: void |
__unset($property) X-Ref |
The magic unset method is used to unset an object property using the iterator. Example: unset($objectList->foo); This will unset all of the 'foo' properties in the list of DataObject's. param: string $property The name of the property. return: void |
getObjectsKeys($type = 'all') X-Ref |
Gets an array of keys, existing in objects param: string $type Selection type 'all' or 'common' return: array Array of keys |
toArray($associative = true, ...$keys) X-Ref |
Gets all objects as an array param: boolean $associative Option to set return mode: associative or numeric array. param: string ...$keys Unlimited optional property names to extract from objects. return: array Returns an array according to defined options. |
count() X-Ref |
Gets the number of data objects in the set. return: integer The number of objects. |
clear() X-Ref |
Clears the objects in the data set. return: DataSet Returns itself to allow chaining. |
current() X-Ref |
Get the current data object in the set. return: DataObject|false The current object, or false if the array is empty or the pointer is beyond the end of the elements. |
dump($depth = 3, \SplObjectStorage $dumped = null) X-Ref |
Dumps the data object in the set, recursively if appropriate. param: integer $depth The maximum depth of recursion (default = 3). param: \SplObjectStorage $dumped An array of already serialized objects that is used to avoid infinite loops. return: array An associative array of the data objects in the set, dumped as a simple PHP stdClass object. |
jsonSerialize() X-Ref |
Gets the data set in a form that can be serialised to JSON format. Note that this method will not return an associative array, otherwise it would be encoded into an object. JSON decoders do not consistently maintain the order of associative keys, whereas they do maintain the order of arrays. return: array |
key() X-Ref |
Gets the key of the current object in the iterator. return: integer|false The object key on success; false on failure. |
keys() X-Ref |
Gets the array of keys for all the objects in the iterator (emulates array_keys). return: array The array of keys |
walk(callable $funcname) X-Ref |
Applies a function to every object in the set (emulates array_walk). param: callable $funcname Callback function. return: boolean |
next() X-Ref |
Advances the iterator to the next object in the iterator. return: void |
offsetExists($offset) X-Ref |
Checks whether an offset exists in the iterator. param: mixed $offset The object offset. return: boolean |
offsetGet($offset) X-Ref |
Gets an offset in the iterator. param: mixed $offset The object offset. return: DataObject|null |
offsetSet($offset, $object) X-Ref |
Sets an offset in the iterator. param: mixed $offset The object offset. param: DataObject $object The object object. return: void |
offsetUnset($offset) X-Ref |
Unsets an offset in the iterator. param: mixed $offset The object offset. return: void |
rewind() X-Ref |
Rewinds the iterator to the first object. return: void |
valid() X-Ref |
Validates the iterator. return: boolean |
initialise(array $input = []) X-Ref |
Initialises the list with an array of objects. param: array $input An array of objects. return: void |
