Member Function Documentation

◆ add()

ilBuddySystemArrayCollection::add ( mixed $element )

Adds an element at the end of the collection.

-param T $element

Here is the caller graph for this function:

◆ clear()

ilBuddySystemArrayCollection::clear ( )

Clears the list.

Implements ilBuddySystemCollection.

     }

◆ contains()

ilBuddySystemArrayCollection::contains ( mixed $element )

-param T $element

Returns: bool true if the collection contains the element, false otherwise.

Implements ilBuddySystemCollection.

Definition at line 118 of file class.ilBuddySystemArrayCollection.php.

     }

◆ containsKey()

ilBuddySystemArrayCollection::containsKey ( string|int $key )

isset is used for performance reasons (array_key_exists is much slower).

array_key_exists is only used in case of a null value (see https://www.php.net/manual/en/function.array-key-exists.php Example #2 array_key_exists() vs isset()).

Parameters

int	$offset	The offset to start from.
int \| null	$length	The maximum number of elements to return, or null for no limit.
