Méthodes publiques

Méthode	Description
cycle ( array \| Iterator \| IteratorAggregate \| Enumerable $source ) : Enumerable	Cycles through the source sequence.
emptyEnum ( ) : Enumerable	Returns an empty sequence.
from ( array \| Iterator \| IteratorAggregate \| Traversable \| Enumerable $source ) : Enumerable	Converts source into Enumerable sequence.
generate ( callable $funcValue, mixed $seedValue = null, callable \| null $funcKey = null, mixed $seedKey = null ) : Enumerable	Generates a sequence by mimicking a for loop.
matches ( string $subject, string $pattern, integer $flags = PREG_SET_ORDER ) : Enumerable	Searches subject for all matches to the regular expression given in pattern and enumerates them in the order specified by flags.

Method Details

cycle() public static méthode

Syntax: cycle (source)

Source keys are discarded.

public static cycle ( array \| Iterator \| IteratorAggregate \| Enumerable $source ) : Enumerable
$source	array \| Iterator \| IteratorAggregate \| Enumerable	Source sequence.
Résultat	Enumerable	Endless list of items repeating the source sequence.

emptyEnum() public static méthode

Syntax: emptyEnum ()

public static emptyEnum ( ) : Enumerable
Résultat	Enumerable

from() public static méthode

Syntax: from (source)

Result depends on the type of source:

array: Enumerable from ArrayIterator;
Enumerable: Enumerable source itself;
Iterator: Enumerable from Iterator;
IteratorAggregate: Enumerable from Iterator returned from getIterator() method;
Traversable: Enumerable from the result of foreach over source.

public static from ( array \| Iterator \| IteratorAggregate \| Traversable \| Enumerable $source ) : Enumerable
$source	array \| Iterator \| IteratorAggregate \| Traversable \| Enumerable	Value to convert into Enumerable sequence.
Résultat	Enumerable

generate() public static méthode

Syntax: generate (funcValue {(v, k) ==> value} [, seedValue [, funcKey {(v, k) ==> key} [, seedKey]]])

If seedValue is null, the first value will be the result of calling funcValue on seedValue and seedKey. The same applies for seedKey.

public static generate ( callable $funcValue, mixed $seedValue = null, callable \| null $funcKey = null, mixed $seedKey = null ) : Enumerable
$funcValue	callable	{(v, k) ==> value} State update function to run on value after every iteration of the generator loop. Default: value.
$seedValue	mixed	Initial state of the generator loop for values. Default: null.
$funcKey	callable \| null	{(v, k) ==> key} State update function to run on key after every iteration of the generator loop. Default: increment.
$seedKey	mixed	Initial state of the generator loop ofr keys. Default: 0.
Résultat	Enumerable

matches() public static méthode

Syntax: matches (subject, pattern [, flags])

range() public static méthode

Syntax: range (start, count [, step])

Keys in the generated sequence are sequental: 0, 1, 2 etc.

Example: range(3, 4, 2) = 3, 5, 7, 9.

public static range ( integer $start, integer $count, integer $step = 1 ) : Enumerable
$start	integer	The value of the first integer in the sequence.
$count	integer	The number of integers to generate.
$step	integer	The difference between adjacent integers. Default: 1.
Résultat	Enumerable	A sequence that contains a range of integral numbers.

rangeDown() public static méthode

Syntax: rangeDown (start, count [, step])

Keys in the generated sequence are sequental: 0, 1, 2 etc.

Example: rangeDown(9, 4, 2) = 9, 7, 5, 3.

$start	integer	The value of the first integer in the sequence.
$count	integer	The number of integers to generate.
$step	integer	The difference between adjacent integers. Default: 1.
Résultat	Enumerable	A sequence that contains a range of integral numbers.

rangeTo() public static méthode

Syntax: rangeTo (start, end [, step])

Keys in the generated sequence are sequental: 0, 1, 2 etc.

Example: rangeTo(3, 9, 2) = 3, 5, 7, 9.

public static rangeTo ( integer $start, integer $end, integer $step = 1 ) : Enumerable
$start	integer	The value of the first integer in the sequence.
$end	integer	The value of the last integer in the sequence (not included).
$step	integer	The difference between adjacent integers. Default: 1.
Résultat	Enumerable	A sequence that contains a range of integral numbers.

repeat() public static méthode

Syntax: repeat (element)

Generates an endless sequence that contains one repeated value.

Syntax: repeat (element, count)
