pht\Vector::insertAt — Inserts a value into the vector

Descrierea

public pht\Vector::insertAt ( mixed $value , int $offset ) : void

This method inserts a value at the specified offset into the vector (in linear time). The vector will automatically be resized if it is not large enough.

Parametri

value: The value to be inserted into the vector. This value will be serialised (since it may be passed around between threads).
offset: The offset at which the value will be inserted at. This offset must be within the 0..N range (inclusive), where N is the size of the vector. Inserting at position N is the equivalent of using pht\Vector::push(), and inserting at position 0 is the equivalent of using pht\Vector::unshift(). Attempting to insert at offsets outside of this range will result in an Error exception.

Valorile întoarse

No return value.

Exemple

Example #1 Inserting a value into a vector


<?php

use pht\Vector;

$vector = new Vector();

$vector->insertAt(3, 0); // insert 3 at start
$vector->insertAt(1, 0); // insert 1 at start (before 3)
$vector->insertAt(2, 1); // insert 2 in middle (after 1 and before 3)

var_dump($vector);
