pht\Vector::updateAt

(PECL pht >= 0.0.1)

pht\Vector::updateAtUpdates a value in the vector

Description

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

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

Since the pht\Vector class supports array access, updating values can also be performed using the array subset notation ([]).

Parameters

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 updated at. This offset must be within the 0..(N-1) range (inclusive), where N is the size of the vector. Attempting to update at offsets outside of this range will result in an Error exception.

Return Values

No return value.

Examples

Example #1 Updating a value in a vector

<?php

use pht\Vector;

$vector = new Vector();

$vector[] = 1;
$vector[] = 2;

$vector->updateAt(30);
$vector[1] = 4;

var_dump($vector);

The above example will output:

object(pht\Vector)#1 (2) {
  [0]=>
  int(3)
  [1]=>
  int(4)
}
